Flood early warning system
This project will install a flood forecasting system to provide early warning during flood events in the Dumaresq Creek catchment. The system will provide predictive information on flows, depths, and velocities of events to the council and the NSW State Emergency Service. This will enable early action during flood events that may impact private property, businesses, public roads, utilities infrastructure and pose a risk to the public.
Guyra flood study
Guyra is a township on the northern tablelands, which is the 'top of the hill' and is not directly impacted by a named watercourse. Overland flow paths collect water and discharge into several water courses, effectively acting as the head of the catchment. This flood study will facilitate strategic planning for the growth of Guyra. This study will identify properties at risk from overland flows and flood paths.
Ballina Shire Council: Ballina Island and West Ballina – local stormwater drainage management study and plan
The Ballina Island and West Ballina area is susceptible to local overland flooding. A detailed investigation of overland flooding risk was completed for the council in 2021. It focused on local overland flood behaviour and recommended floodplain mitigation measures. The associated 2-dimensional hydrodynamic model (TUFLOW) of the trunk drainage system provided inundation mapping of local storm events and backwater inundation (high tide scenarios). This project addresses strategy 7 in the plan, which recommended commissioning a local stormwater drainage management study and plan.
Blacktown City Council: Wianamatta South Creek catchment flood study review
The project will undertake an independent review of the Wianamatta South Creek catchment flood study, to incorporate local information of newly developed areas within the South Creek catchment. The Wianamatta South Creek catchment flood study has been prepared by Infrastructure NSW, based on the council's 2015 South Creek flood study. The review of the flood study will ensure that the work has made the best use of information, the assumptions can be justified, and that the council can use the spatial flood information and modelling tools as a suitable foundation for developing a floodplain management plan.
Cabonne Council
Cabonne Council received funding for 2 projects.
Canowindra floodplain risk management study and plan review
Canowindra was significantly impacted by flooding in November 2022, resulting in substantial damage to private properties and infrastructure. The Canowindra floodplain risk management study and plan (FRMSP) was completed in 2007. Since the completion of the Canowindra floodplain risk management study and plan, the township has been impacted by flooding in 2010, 2012, 2016 and 2022. The nature and extent of flooding in Canowindra needs to be reviewed, including the calibration and verification of the flooding that has occurred since 2007; particularly the major flooding experienced in November 2022. This updated information will facilitate a review and update of the flood mitigation options and ensure council continues to implement the most appropriate options.
Eugowra floodplain risk management study and plan review
Eugowra was devastatingly impacted by flooding in November 2022, substantially damaging private properties and infrastructure. The Eugowra floodplain risk management study and plan (FRMSP) was completed in 2010. Since the completion of the Eugowra floodplain risk management study and plan, Eugowra has been impacted by flooding in 2005, 2012, 2016 and 2022. The nature and extent of flooding in Eugowra needs to be reviewed and updated, including the calibration and verification of the flooding that has occurred since 2010; particularly the major flooding experienced in November 2022. This updated information will facilitate a review and update of the flood mitigation options recommended for this area.
Central Darling Shire Council: Central Darling Shire floodplain risk management study and plan
This project will deliver a comprehensive floodplain risk management study and plan for the Central Darling Shire, focusing on the townships of Wilcannia, Menindee, Tilpa and The Sunset Strip. The project will build on the work done in the Darling River flood mapping project. It will enable the Central Darling Shire to accurately plan for and deliver future infrastructure developments whilst taking the necessary steps to provide appropriate mitigation for the impact of floods. It will also review the NSW State Emergency Service flood emergency sub-plan for the Shire.
City of Newcastle: Hexham and Woodberry swamp flood study
Hexham and Woodberry swamp are located on the lower Hunter River floodplain, within the local government areas of City of Newcastle, Cessnock and Maitland councils. The local catchments for Hexham and Woodberry swamp are experiencing significant development pressure from upper catchment development, redevelopment, and densification in low-lying areas adjacent to the wetlands. Of the 8 main tributaries that flow into Hexham Swamp, flood modelling has only been undertaken for the local catchments of Ironbark and Dark Creek, in 2008. Flood impacts and behaviour across the remaining tributaries of Hexham and Woodberry swamp is based on Hunter River flood modelling. The flood study aims to identify local catchment flood risk and behaviours, taking into consideration significant infrastructure projects and developments that have occurred, to inform future development, appropriate planning controls, and future mitigation measures.
Council of the City of Parramatta: Upper Devlins Creek flood study and floodplain risk management study and plan
This location is the only remaining area within City of Parramatta for which no flood study has been completed. This project will enable the council to apply a consistent approach over the entire council area for floodplain management.
Council of the City of Sydney: Update of Darling Harbour and City area flood study
The existing flood studies for the City area and Darling Harbour catchments were completed in 2014. Since then, major public infrastructure and private development have changed large parts of these catchments. Updating the flood studies will capture these major changes and provide a contemporary definition of flood behaviour in the highly urbanised catchments. Assessment of the risk of estuarine inundation will also be included, defining risk from an additional source compared to the existing flood studies. This will increase the reliability of flood information for strategic land use planning across the study areas and the assessment of proposed developments on flood-prone land, particularly for ongoing major developments in the Sydney central business district and for future development in Pyrmont.
Dubbo Regional Council: Wellington flood study
Most of Wellington is considered flood-free, but when flooding occurs, it results from floodwaters overtopping the banks of the Bell River, with areas around the main commercial precinct and some low-lying properties becoming inundated. This project will update the flood study, which was completed in 1995.
Dungog Shire Council: Clarence Town flood study
Clarence Town is a small township located on the Williams River, 25 kilometres south of Dungog and 55 kilometres north of Newcastle. Flood studies have previously been completed for the local Clarence Town catchment (2012) and the wider Williams River catchment (2009). The primary objective of the flood studies was to define the flood behaviour of Clarence Town and the Williams River by establishing appropriate numerical models. This project aims to minimise the flood risk and allow development on land compatible with the land's hazard.
Goulburn Mulwaree Council: Goulburn overland flooding risk study and management plan project
This two-stage project will inform the council's planning and engineering processes in relation to the impacts of overland flooding, including potential risk to life and property damage for Goulburn. Stage one will involve completing a flood study to provide a basis to define overland flood behaviour for Goulburn. The flood study will examine past overland flood events and evaluate overland flood assessments for a range of designed storms events under existing conditions. Stage 2 will develop an associated floodplain risk management study and plan to inform the council on managing future overland flood risk impacts.
Griffith City Council: Review of Lake Wyangan flood study and floodplain risk management study and plan
The Lake Wyangan flood study was undertaken with limited historical flood information. Soon after its completion, the March 2012 flood event occurred. The 2012 flood event information was incorporated into the floodplain risk management study and plan (2013) enabling the design flood level estimations to be consistent. However, since then the Lake Wyangan catchment has experienced 2 more flood events in 2016 and 2022, these flood events were a result of a prolonged wet period with saturated soil conditions and an accumulation of several minor storm events. Additionally, significant agricultural development has occurred in the last 10 years around Dickie Road. These are the main reasons for the review of the floodplain risk management study and plan.
Lachlan Shire Council: Lachlan River flood study – Condobolin to Lake Brewster
The Lachlan River downstream of Condobolin has no flood information or flood planning levels. This includes the townships of Lake Cargelligo, Curlew Waters, Euabalong, Euabalong West, Murrin Bridge and rural properties along the floodplain. The flooding event experienced in late 2022, was the largest on record. Completing a flood study for this section of the Lachlan River, after such a significant event, will provide benefits for infrastructure and housing planning.
Leeton Shire Council: flood study review and update
The project area includes the towns of Leeton, Whitton, Yanco, Murrari and the main irrigation channel originating at the Murrumbidgee River. The previous flood study was completed in 2015, after the March 2012 floods. The council will use improved study results to build community resilience through awareness of and preparedness for flood events, as well as influencing future town planning and ensuring new development areas have appropriate flood protection and emergency evacuation routes. The flood study will also be used to assess the stormwater drainage capacity of existing infrastructure within the towns and provide a basis upon which drainage augmentation works can be undertaken.
Liverpool City Council: Review of Liverpool overland flow path study for urban catchment area – stage one, Cabramatta Creek catchment
In 2006, council completed a broad overland flow path study of the entire local government area to identify and prioritise sub-catchments prone to overland flooding. Subsequently, the council undertook detailed overland flow path and risk management studies of the high-priority urban sub-catchment areas. Over the past decade, extensive development has occurred across the Liverpool local government area. Landform has been changed due to the construction of new residential developments, subdivision of lands, and construction of roads and infrastructures. In addition to physical changes in landform, rainfall pattern and intensity have also been changed due to the impact of climate change. It has become necessary to review the local government area wide overland flow path study using the latest LiDAR data and newly adopted hydrological methodology Australian rainfall and runoff 2019. The study will identify overland flow paths within the study area and prioritise local sub-catchments for further detailed studies.
Maitland City Council: Maitland local government area – floodplain risk management study and plan
Maitland Council will comprehensively review and update the existing Hunter River floodplain risk management study and plan (2015). The project objective is to develop a new local government area-wide floodplain risk management study and plan, incorporating the results of recent flood studies to ensure that the risks of both riverine and local catchment flooding are appropriately managed across the entire local government area.
Murray River Council
Murray River Council received funding for 3 projects.
Moama major overland flow flood study
Murray River Council is currently undertaking the cross-border Echuca-Moama flood study. The proposed Moama major overland flow flood study will compliment that study and provide vital information on how overland flows impact the town. Residential development in Moama is flood-sensitive; therefore, this study will help the council implement measures that foster flood resilience for the community.
Moulamein flood study review
This project will review the Moulamein flood study (2019) and validate it to the November 2022 flood event. The Moulamein township is at the confluence of the Billabong Creek and Edward River and has been subjected to recurrent riverine flooding. In recent years, Moulamein was impacted by floods in 2016 and more severely by the 2022 flood. The 2022 flood event far exceeded the 1% annual exceedance probability event and is the biggest in recorded history at the Moulamein gauge. Once the flood study is updated and adopted, the council, NSW State Emergency Service and other government agencies will have access to an appropriate tool for sustainable resilience and the town's preparedness when the next flood hits.
River Estate levee upgrade – Barham
The River Estate levee encloses a residential estate at Barham. The levee was subject to a structural integrity audit in 2019 as part of implementing the Barham floodplain risk management study and plan (2017). The audit report identified that the existing levee does not comply with current standards for urban levees in New South Wales. A detailed design of the levee upgrade was completed in April 2022. This project will reconstruct the existing levee to the adopted design crest level.
Orange City Council ultimate flood modification scheme: feasibility and design project
This project will undertake the next major step of the Blackmans Swamp and Ploughmans Creek floodplain risk management study and plan. It will assess the feasibility of constructing Orange's ultimate flood modification scheme, including preparation of concept designs for 8 individual flood modification schemes: Cutcliffe Park detention basin, Kenna Street stormwater drainage upgrade, Orange Agricultural Institute dam modification, Moulder Park detention basin, Ridley oval detention basin, Glenroi oval detention basin, East Orange Creek channel works and Blackmans Swamp Creek channel widening.
Penrith City Council
Penrith City Council received funding for 2 projects.
Claremont Creek catchment flood study
The council will undertake a detailed local overland flow study for the Claremont Creek catchment and adjoining South Creek and Upper Surveyors Creek locality. The study area contains several overland flow paths and flows from the catchment area contributing to Claremont Creek, South Creek and Ropes Creek. The study area comprises 1,606 hectares within Claremont Meadows, a large part of Orchard Hills and parts of Werrington, Kingswood and Caddens. The study will define the flood behaviour under current floodplain conditions. All potential flooding mechanisms will be included in the analysis of flood behaviour, including local overland flow and creek flooding. This flood study will form the basis for the future flood planning of the study area.
Jamison Road and Stafford Street retarding basins, Kingswood – investigation and detailed design
The College, Orth and Werrington creeks floodplain risk management plan (2021) recommends upgrading the Jamison Road existing retarding basin and constructing a new retarding basin at Stafford Street, Kingswood. These flood mitigation measures are part of combined flood mitigation measures that aim to provide greater attenuation of flows during more significant floods in the catchment. The project will complete detailed design plans for these 2 retarding basins ready for construction.
Richmond Valley Council floodplain risk management plan
This project will produce a floodplain risk management plan (FRMP) for the Richmond Valley, with the overall objective of improved management of flood risk into the future.
The Richmond Valley FRMP will outline a range of measures to manage existing, future, and residual flood risk effectively and efficiently. The FRMP will also present a prioritised strategy to guide the implementation of the proposed measures; to build a more resilient community, with reduced impacts from flooding on individual owners and occupiers of flood prone property.
Snowy Valleys Council: Brungle flood study
This flood study will focus on the village of Brungle, which is partially located on the Tumut River floodplain (including the anabranch of Nimbo Creek) and the tributary of Brungle Creek. This flood study will initially develop a hydraulic model of the Tumut River floodplain that will connect to the Tumut flood study upstream and the Gundagai flood study downstream. A detailed hydraulic model will then be developed to define the flood risks and provide a tool suitable to progress to a floodplain risk management study and plan.
Sutherland Shire Council: Woronora River flood study
The Woronora River flood study (1991) is over 30 years old. This project will complete a flood study using the latest hydrologic and hydraulic modelling techniques, Australian rainfall and runoff 2019 guidelines and sea level rise policy. The flood study will determine revised flood behaviour, hazard and risk to life and property. The study will be used to improve the application of the council's flood related development controls, providing flood information to community, and for emergency response management planning.
Tenterfield Shire Council: Urbenville and Woodenbong floodplain risk management study
This project continues the work undertaken to prepare flood mapping for the 2 shires of Tenterfield and Kyogle. The towns of Urbenville, Muli Muli an Aboriginal community, and Woodenbong share the Tooloom Creek catchment. Undertaking the risk management study jointly allows a greater understanding of the issues faced by border villages and enhanced cooperation in the face of natural disasters, such as flooding.
The Council of Camden: Addendum to Nepean River floodplain risk management study and plan to support emergency management planning
The study area is the Nepean River catchment in Camden local government area. This project will review the Nepean River floodplain risk management study and plan to support emergency management planning. The Nepean River catchment is vulnerable to flooding and subject to rapid development and the community has faced difficulties with emergency management during 3 flood events in 2022. The purpose of this study is to:
- provide key consideration for emergency response strategy including evacuation capability, emergency management for fast responding catchments
- identify areas with no defined emergency management strategy
- address emergency management principles in floodplain risk management decisions based on emergency management guideline to support emergency management planning
- provide the community with awareness, understanding of how flooding impacts them and the response arrangements during floods.
The Council of the Municipality of Kiama
The Council of the Municipality of Kiama received funding for 2 projects.
Jamberoo floodplain risk management study and plan
This project will progress the Jamberoo flood investigation (Gerringong Jamberoo flood investigation – catchment simulation solutions 2022) to the floodplain risk management stage. A floodplain risk management plan will review flood measures, including options to improve flood-resistant access, confirm the suitability of the proposed flood mitigation measures, conduct an analysis using Australian rainfall and runoff 2019, establish flood planning levels and develop emergency control plans.
Spring Creek flood study and flood risk management plan
This project will update and review the existing study, to include the methodology of Australian rainfall and runoff 2019. Following the study, the council will progress to a flood risk management plan. The intended outcome is to improve flood-resistant access across Spring Creek at Dido Street and Jamberoo Road, provide suitable flood mitigation measures, establish flood planning levels and provide appropriate flood information to the NSW State Emergency Service to inform the emergency response plan.
Tweed Shire Council: Tweed coastal creeks floodplain risk management study and plan update
Since the completion of the Tweed coastal creeks flood study and floodplain risk management study and plan several years ago, the Tweed region has suffered two devastating floods of record, being the March 2017 event and the February–March 2022 flood events.
The Tweed coastal creeks floodplain risk management study and plan update will revise the coastal creeks flood models, revisit the risk management study, and update the risk management plan, which will help council to better manage flood risk in the area.
Upper Lachlan Shire Council: Supply and installation of flood warning systems at Crookwell, Collector, Gunning and Taralga
There is a major issue with flash flooding of the townships of Crookwell, Collector, Gunning and Taralga. The State Emergency Service (SES) and council do not have adequate time to conduct evacuation and flood damage reduction measures. This project includes the following benefits:
- automated warning provided to SES and council, which improves reliability and ability to respond and reduces reliance on personnel to monitor conditions
- real-time rainfall and water level data hosted by the Bureau of Meteorology to assist the SES, council and the community with decision-making
- historical data recording to assist with greater accuracy of flood predictions, modelling and understanding potential impacts on the community.
Warrumbungle Shire Council: Coolah catchment flood study
Coolah Catchment is a small catchment area often subject to heavy rainfall and flash flooding. The village of Coolah is at the bottom of the catchment, and the flooding is often quick and short, creating considerable damage to properties and infrastructure. Through this flood study, the council will capture data to enable flood modelling, including analysis of tributary catchments to determine flows for required events, including 1%, 2% and probable maximum flood, as well as more frequent events.
Wingecarribee Shire Council: Review of Bowral floodplain risk management study and plan
A floodplain risk management study and plan was completed in 2009 for the Mittagong Creek catchment in Bowral. This review will assess the earlier recommendations and suggest new options to further mitigate flooding in the catchment. It is intended that the review will use current modelling techniques to identify alternative measures and new flooding information that reflects the change in land use over the last 14 years. The review will model mainstream flooding and overland flow using 1-dimensional/2-dimensional techniques to better represent the complex interactions in the catchment.

Project details
Ballina Shire Council
Alstonville, Lennox Head and Wardell overland flood study
This project will develop a 2-dimensional hydraulic model of the urban areas of Alstonville, Lennox Head and Wardell to analyse and map local overland flooding extents. The flood study and extents mapping will be used to implement development controls, inform land-use planning, and identify feasible infrastructure upgrades and structural protection measures available to reduce the impacts of overland flooding to Alstonville, Lennox Head and Wardell.
Bayside Council
Mascot, Rosebery and Eastlakes flood study review
The Mascot, Rosebery and Eastlakes catchment includes the suburbs of Mascot, Rosebery, Eastlakes and Pagewood. This catchment is affected by overland flooding and mainstream flooding.
Flood modelling for this catchment was completed based on parameters available in 2013. Since then, LiDAR information, building footprints, roads, and rainfall guidelines have changed significantly. This project will review and update the current flood study based on the latest information.
Bega Valley Shire Council
Wolumla flood study and floodplain risk management plan
Wolumla Creek is a tributary of the Bega River. Two regional roads transit the Wolumla Creek catchment. Detailed flood information is needed for emergency response and infrastructure planning.
An overland flow study covering the township of Wolumla will provide information on flood risk. The study area will encompass the Wolumla Creek catchment focusing on the localities of Wolumla, South Wolumla and Frog's Hollow.
The floodplain risk management plan will provide the council with some definitive actions to manage the flood risk within the catchment and deliver information to inform the council's future land-use and emergency response planning.
Blacktown City Council
Eastern Creek floodplain risk management study and plan
The Eastern Creek lower catchment comprises large areas significantly impacted by the Hawkesbury Nepean flooding. This area is of significant importance because it includes the North West growth area, the Western Sydney employment area and the Greater Penrith to Eastern Creek investigation area.
A floodplain risk management study and plan are the next steps for the Eastern Creek catchment, following the completion of the Eastern Creek flood study in 2019. This project will investigate a suite of flood management measures and evaluate options that could be implemented to manage the existing, future and continuing flood risk.
Broken Hill City Council
Broken Hill flood study
This project will complete a flood study of the Broken Hill local government area to determine and define the overall flood risk to the community. The flood risk will be identified through the development of a state-of-the-art flood model that will be used to determine:
- the degree of hazard the community is exposed to
- the scale of the population at risk
- gaps in flood information needed to manage flooding
- the potential need for flood mitigation works to reduce risks to the community in the area
- the potential for redevelopment and new development.
Byron Shire Council
Belongil and Tallow flood risk management study and plan update
The Belongil and Tallow Creek floodplain risk management study and plan are more than 5-years old and require updating, due to the development pressure in these catchments and recent flood events. This project will update the floodplain risk management study and plan to align them with current Australian standards.
Byron Shire overland flow path study
This project will undertake shire-wide overland flow path flooding and drainage studies to identify and prioritise flooding and drainage improvement mitigation upgrade works for the shire. The project will identify and prioritise potential mitigation works with the highest benefit-cost ratio to aid strategic land-use planning.
Camden Council
Investigation and design for building a levee from Saunders Road and along McCrae Drive
The draft Nepean River floodplain risk management plan recommends a flood protection levee west of McCrae Drive from Saunders Avenue to Cunningham Place as a high-ranked flood management measure for the Nepean River catchment. This project will investigate whether the proposed levee is a viable option to reduce flood levels for properties along McCrae Drive.
Update Nepean River flood study to include precinct development and urban land release
This project will update the Nepean River flood study to include changes in the catchment, such as precinct development and urban land release. The Nepean River flood study was based on LiDAR information captured in 2011, and there has been significant development in the catchment since then. The study will assess the cumulative impact of development on flooding, to address this issue in emergency management and land-use planning. It will help to understand the flood behaviour and risk and provide up-to-date flood information to the public.
Carrathool Shire Council
Hillston eastern levee upgrade feasibility study
The current Hillston floodplain risk management study and plan highlight the benefit of restoring and upgrading the eastern levee at Hillston; this option would potentially protect up to 73 buildings from above floor-level flooding during a 1% annual exceedance probability flood event. This site is also the location of a proposed heavy vehicle bypass. A feasibility study to investigate the possibility of incorporating a dual levee and heavy vehicle bypass at this location will be undertaken as part of the project.
Central Coast Council
Somersby and Kariong catchments overland flood study
The overland flood study area consists of the Somersby and Kariong catchments. The catchments drain to the Hawkesbury River via Mooney Mooney Creek and other smaller tributaries. Council currently has very limited flooding information for these catchments. This study will produce a 2-dimensional hydraulic model and inform planning decisions about the growth in this area, which has been identified as a regionally significant growth area.
City of Canterbury Bankstown Council
Floodplain risk management study and plan for sub-catchments of the Duck River
Duck River is one of the major tributaries of the Parramatta River and drains water from 2 sub-catchments: Wolumba and Duck River. The total catchment area is approximately 9.17 square kilometres and will accommodate substantial growth and development over the coming years. Significant floods have occurred in the Duck River catchment, including in March 2022.
This project will undertake Australian rainfall and runoff 2019 sensitivity analyses for the 2 sub-catchments and prepare a consolidated floodplain risk management plan for the Duck River catchment.
Clarence Valley Council
Esk River flood monitoring project
This project will install a remotely monitored flood gauge in the Esk River on Iluka Road.
Iluka Road provides the only access to the town of Iluka, and flooding of the Esk River has caused the road to be closed on multiple occasions. Council relies on community reports to know when the road has been cut by floodwater. The flood gauge will enable the council to advise the Iluka community about road closures.
Coffs Harbour City Council
Bonville Creek flood study
The Bonville Creek catchment covers an area of approximately 115 square kilometres. Two major tributaries join Bonville and Pine creeks from the south, and Middle Creek from the north. The existing flood study for the catchment was completed in 1995. There is ongoing development pressure in the catchment. This study will provide up-to-date, detailed and accurate flood mapping. This will provide a sound base for implementing flood planning controls and better inform strategic plans for improving flood immunity.
Coonamble Shire Council
Coonamble stage 4a levee – high bank stabilisation along Castlereagh River
This project will stabilise the high bank of the Coonamble levee adjacent to the Castlereagh River and the Sir Edward Hollstrom Bridge using oversized rock.
