This Port Phillip and Western Port Regional Catchment Strategy is a guide to conserving our region’s land, waters and biodiversity so they continue to sustain and enrich life, economies, health and social wellbeing for this and future generations.
Researching and compiling this region-scale Strategy is a major responsibility of the Port Phillip & Westernport Catchment Management Authority. This fourth edition builds on 25 years of learning and experience in supporting collaborative achievement by Councils, Government agencies, public utilities, community organisations, businesses, farmers, landholders and citizens.
This Strategy recognises Traditional Owners as the voice for their Country and their rights to pursue their aspirations for its waterways, land and biodiversity.
Background and purpose of this strategy
This Regional Catchment Strategy’s overarching aim is to foster collaboration towards its vision of a healthy and resilient environment and well-managed natural resources.
To do this, the Strategy describes our region’s land, water, biodiversity, coastal and marine environments:
- Water supply, waterways, wetlands and groundwater
- Native vegetation and native animals
- Land use, soil health and agriculture
- Coasts, estuaries and marine environments
- Community connections and volunteering.
It explains why and where the values of these natural resources are persisting, declining or sustained. It illustrates how the use and condition of a natural resource can affect the others around or connected to it. It describes the pervasive challenge posed by climate change.
The Strategy recognises the long and proud history of environmental stewardship by Traditional Owners and how their knowledge and practice need to be restored to natural resource management.
The strategy describes the current conservation policies and plans of some fifty agencies and organisations. It then uses these to express a region-scale vision and a comprehensive set of targets for the future condition of the region’s natural resources. The targets are designed to be pursued as common goals by multiple organisations working together.
The strategy then provides a Prospectus of project proposals that can contribute to achieving the Strategy’s targets and vision.
This Regional Catchment Strategy was developed in accordance with the requirements of national and state legislation and policies for biodiversity, land and water resources. In particular, it was prepared under the provisions of the Victorian Catchment and Land Protection Act 1994 in line with two of its key purposes:
- To set up a framework for the integrated management and protection of catchments
- To encourage community participation in the management of land and water resources.
The Port Phillip and Western Port region
The Port Phillip and Western Port region is home to more than five million people and includes all of urban Melbourne, growth centres on the urban fringe, highly productive farming land, forested parks and ranges, and a network of rivers, wetlands and estuaries which flow to our two valuable bays – Port Phillip Bay and Western Port.
The region supports a range of non-urban land uses located on or near the urban fringe that are critical to the functioning of urban Melbourne. These include tourism, airports, water treatment plants, extractive industries, waste and resource recovery operations and renewable energy infrastructure. It is important to ensure these uses are located in areas that have as little impact as possible on biodiversity and other natural and cultural values.
The impact of growing populations on land, waterways and the bays and the competition for space between rural, urban and coastal land uses, industry, infrastructure, recreation and conservation pose complex challenges for sustainable use of the region’s natural resources and biodiversity.
Climate change will exacerbate these and other environmental pressures, such as drought, wildfire, weeds and pest animals on natural habitats and biodiversity. Climate change is likely to be making obsolete and perilous the trade-offs between development and conservation used in previous ‘balanced decision-making’.
This region is the Country of the Bunurong, Wurundjeri Woi-wurrung and Wadawurrung people. They have lived in and been connected to the land, water, plants and animals of this area for many thousands of years, and continue to do so.
The Bunurong, Wurundjeri Woi-wurrung and Wadawurrung people are acknowledged as the Traditional Owners of these lands and waters. They are recogniosed as the voice for their Country.

Vision for the region
A healthy and resilient environment in the Port Phillip & Western Port region
In 2050, people and organisations across the Port Phillip & Western Port region will be collaborating to protect and improve the extent, quality and diversity of its environmental assets. There will be shared leadership in planning, decision making, action, monitoring and reporting that ensures targets for all environmental assets are set and pursued to contribute to the natural ecosystems being healthy and resilient.

Themes of this strategy
Building blocks of a healthy and resilient environment
The 15 ‘Themes’ that are the focus of this Regional Catchment Strategy are building blocks of a healthy and resilient environment for this region.
There is an analysis for each of:
- Water – Water supply and use, Waterways, Wetlands, Groundwater
- Biodiversity – Native vegetation, Native animals
- Land – Land use, Soil health, Sustainable agriculture
- Coastal and marine environments – Coasts, Estuaries, Marine environments
- Community sectors – Traditional Owners and Aboriginal Victorians, Communities
There is also a section recognising the significant and pervasive issue of Climate change.
For each theme, there is information on:
- The main policy and planning that is in place for that theme
- The current condition and trends
- Major threats and drivers of change
- The vision and targets for future condition
- Partners and supporters to help achieve the targets
- A list of some projects that can help us move forward.
Integration and partnerships in your local area
The following nine ‘Local Areas’ are described in this Regional Catchment Strategy with explanation of how the themes come together and interact in each place.
- Bass Coast, South Gippsland & islands
- Casey, Cardinia & Baw Baw
- Mornington Peninsula
- Yarra Ranges & Nillumbik
- Urban Melbourne
- Macedon Ranges, Hume, Mitchell & Whittlesea
- Moorabool, Melton, Wyndham & Greater Geelong
- Port Phillip Bay
- Western Port.
The purposes of describing the region in this way are to:
- Recognise the significant differences between different parts of this large region
- Break the Regional Catchment Strategy down to sub-regional level so it is more meaningful and useful for local residents and communities
- Consider how the themes of natural resource management interact in each particular area
- Enable the vision, knowledge and priorities of local organisations and communities to be highlighted
- Promote the value of organisations and communities working together at local scale.
The section on each Local Area includes:
- Overview of the community and environmental values of the area
- Current condition of the environment and significant trends
- Major challenges and drivers of change
- Vision and targets for the future
- Organisations that support the directions of this strategy
- Priority projects that can help us move forward.
The following long-term targets (at the year 2050 or further) will contribute to achieving the vision for this region and help ensure this region remains healthy and prosperous for future generations.
1.1 Water supply and use
Adequate and stable water supplies have been secured for households, businesses, farms, Traditional Owners and the environment. Various water supply options have been effectively harnessed including stormwater harvesting, manufactured water and recycled water use. Water is shared, distributed and used efficiently by all users.
1.2 Water for the environment
The environmental water reserve has been increased by at least 1-5 GL/yr in the Westernport catchment, 15-25 GL/yr in the Yarra catchment and 10-20 GL/yr in each of the Maribyrnong and Werribee catchments, and an average score of HIGH has been achieved for each of those catchments.
1.4 Water for agriculture
Significant volumes of recycled water and stormwater have boosted agricultural water supply and security in the region’s irrigation districts, green wedges, peri-urban and rural areas. Major irrigation systems have been modernised to ensure efficient water delivery and use, and new irrigation networks have been established in suitable areas.
5.1 New parks
At least 6,500 hectares of new suburban parks established in the region by 2027. At least 15,000 hectares of a new Western Grassland Reserve and 1,200 hectares of a new Grassy Eucalypt Woodland Protected Area established in this region by 2037. Significant areas of additional new parks established across this region by 2050 providing improved security, extent and quality of native habitat.
7.1 Land use
While planned urban development progresses in the region, the extent and quality of native vegetation, significant landscapes, cultural heritage values and environmental assets are retained. Water supply catchments, state significant infrastructure, extractive resources, open space areas and agriculture are carefully planned for and protected. Sufficient extent and quality of native vegetation and agriculture is retained, including in the Green Wedges, to support healthy ecosystems and agricultural industries.
13.1 Traditional Owners as the ‘voice’ for waterways and Country
Traditional Owners are the strong and respected voice for Country, with fundamental roles and influence in planning, decision making and action across the region in land, biodiversity and water management. The value of traditional ecological knowledge held by the region’s Traditional Owners is embraced and influential in modern decisions and practices.
16.2 Regional investment in natural resource management
The collective investment in natural resource management in the region by key organisations is regularly estimated, has had sustained growth over time, and benefits are being achieved through shared investment, partnerships and increased efficiency.
Systematic and comprehensive links between the Regional Regular, comprehensive reporting on the condition of the region’s natural resources has been undertaken and has influenced the scope and scale of programs to ensure the region’s natural resources are protected and retained in suitable condition.
A Prospectus accompanies this Regional Catchment Strategy. The Prospectus is akin to a ‘stakeholder billboard’ on which organisations summarise their most important, desirable, practical and/or innovative project proposals that can individually and collectively contribute to achieving the strategy’s targets. It is a starting point from which:
- Stakeholders can build a case for funding from within their own organisations (eg. within annual Council budgeting processes) by showing that the project is aligning with regional, state and/or national priorities
- Stakeholders can identify similar or complementary project ideas listed by other organisations and then make a connection and potentially expand or merge their proposals
- Potential investors from the public, private or philanthropy sectors can efficiently browse project ideas across the region (and the connection of each to themes, areas, investment priorities) and identify those they wish to pursue by following up with the project proponent and partners
- Organisations such as Melbourne Water (as the Regional Catchment Strategy coordinator) and/or others can sort the list when a new funding opportunity emerges and create a ‘short list’ of ideas that meet the funding criteria and can be further developed and promoted.
