2017 (actual) moderate low moderatemoderatemoderate low high high high
Current trajectory low high low low low very lowmoderatemoderatemoderate
Waterway Values (10‐50 year targets)• Birds are currently moderate, with 249 species recorded, of which 131 are expected in riparian habitats. Of note is the
Ramsar‐listed Western Port; riparian areas in forested headwaters; Tootgarook Swamp on the Mornington Peninsula; and bird colonies on Phillip Island. The current trajectory is low; and target is to maitain at moderate.
• Fish are currently high, with 18 native freshwater species and eight exotic species recorded in the catchment; includes nationally significant species Dwarf galaxias, Australian grayling , Australian mudfish and pale mangrove goby. The current trajectory is high; and target is to improve to high.
• Frogs are currently moderate, with up to 14 species of frogs expected to occur across the catchment; this includes threatened species such as the Growling Grass Frog and the Southern Toadlet.The current trajectory is low; and target is to maitain at moderate.
• Macroinvertebrates are currently moderate, with scores higher in forested headwaters and lower in areas affected by urbanisation.The current trajectory is low; and target is to maitain at moderate.
• Platypus are currently moderate, with poplulations occurring in rivers and creeks in the Bunyip, Tarago and Lang Lang river systems. The current trajectory is low; and target is to maitain at moderate.
• Vegetation is currently low, but varies from very low to very high, with much of the high areas being in forested upper catchments, along the coast of Western Port, and in the large regional parks. The current trajectory is very low; and target is to improve to moderate.
• Amenity, which is based on level of satisfaction, is currently high but likely to decline with increased urbanisation; target is to improve to very high.
• Community connection, which is based on level of satisfaction, is currently high but likely to decline with increased urbanisation; target is to maitain at high.
• Recreation, which is based on level of satisfaction, is currently high but likely to decline with increased urbanisation; target is to maintin at high.
• Cultural The traditional lands of the Boon Wurrung and Bunurong are in the south and central areas of the catchment, and these lands meet those of the Gunai Kurnai to the far east, and Wurundjeri to the north. More than 2000 Aboriginal sites have been recorded, with most of these occurring near waterways and along the coast .
• Economic Primary industries include dairy farming, beef production, poultry, horticulture and quarrying.
• Stakeholders and the broader community are knowledgeable, engaged and working together to value and improve waterways• creating a legacy of stewardship
• Diverse and abundant native animals and plants are supported through connected habitats within and along waterways and across landscapes• only local indigenous plant species along all streams• impact of feral animals on waterways eliminated
• Waterways across the catchment are managed for long term ecological resilience, balancing the needs for regional flood mitigation, agriculture, industry and urbanisation• water reuse systems offset losses due to climate change• balanced management of natural and modified waterways for fluvial processes
• Waterways across the catchment are managed to maintain and improve coastal and marine ecosystems in Western Port and Port Phillip Bay
Vision: Waterways are highly valued and sustained by an informed and engaged community working together to protect and improve their value.
Westernport Catchment
Goals
Very Low Low Moderate High Very High
Performance objectives (achieve in 1‐10 years)• Improve condition and extent of riparian vegetation in rural and urban areas by protecting high
quality vegetation, managing threats and building resilience • Improve environmental flows and protect drought refuges in the context of climate change• Provide connectivity for fish along major waterways through removal of barriers• Reduce nutrient and sediment runoff from rural land and areas of urban development; ensure no net
increase in nutrient and sediment loads to protect the health of Port Phillip and Western Port Bays• Protect and improve high quality wetlands within the catchment and fill knowledge gaps for
remaining wetlands to inform future management actions• Reduce impacts of stormwater on waterways; focus on urban growth and rural townships• Protect and improve signficant environmental and social values of estuaries, including managing
impacts of climate change• Traditional Owners are supported to recognise, protect and promote intangible and tangible cultural
values and to have a role in protecting and improving waterways• Provide systems to share knowledge and information between communities and stakeholders; to
empower communities to participate and influence waterways management• Protect vegetation, amenity and other social values along the urban creeks • Improve understanding of existing rules around land management practices and increase resourcing
for enforcement, capacity building and behaviour change• Address significant risks to values from pollution (water quality) from emerging contaminants of
concern such as microplastics, pesticides and pharmaceuticals

Western Port Ramsar Site comprises a large proportion of the Western Port embayment to the north of Phillip Island. The site consists of large shallow intertidal areas, dissected by deeper channels and covers approximately 60,000 hectares. The Western Port Ramsar Site contains one of the largest expanses of saltmarsh in Victoria, covering an area of just over 1,100 hectares within the Ramsar site boundary. A total of 115 waterbird species have been recorded within the Western Port Ramsar Site, and it regularly supports 12 species listed under international migratory bird agreements JAMBA, CAMBA and ROKAMBA. The Western Port Ramsar Site provides significant foraging area for a variety of shorebird species as well as important roosting (nesting) sites.

The Balcombe Creek estuary is in Mt Martha. The entrance is downstream of the Nepean Highway and is open intermittently to Port Phillip Bay. The concrete spillway at Briars Park Wildlife Sanctuary limits upstream connectivity and extent but unsure if tidal influence extends to the barrier. The estuary maintains a more natural connection between the floodplain and the waterway. The riparian area has dense covers of Swamp paperbark and Woolly Tea‐tree.

The Bass River estuary has a permanent, natural mouth opening to Western Port and extends up to the Bass Township. The estuary has a sinuous platform comprised of silts and clays, underlain by lagoon and swamp deposits. The estuary is surrounded by flat, open land and is well‐mixed. The estuary provides important habitats for native fish and bird populations and as a fish nursery for shark and whiting.

The Bunyip River estuary is continuously open to Western Port and discharges near Koo Wee Rup. The area of the estuary can be up to 194 m2 and the upper extent is limited by the Water Tower weir. Prior to European settlement, the Bunyip Estuary area was part of the Koo‐Wee‐Rup Swamp, but is now a heavily modified channelised estuary ‐ trapezoidal drain with levees upstream of highway, more natural downstream.The estuary is generally well‐mixed but can be stratified close to high tide. The riparian vegetation is commonly coastal saltmarsh, estuarine wetland and swamp scrub.

The Chinamans Creek estuary flows through the township of Rosebud and discharges into Port Phillip Bay near Tootgarook. When the estuary is open the entrance is approximately 5 m wide but can extend up to approximately 15 m wide further upstream. The creek was constructed to drain Tootgarook Swamp and does not follow a natural drainage line. The riparian vegetation is primarily swamp marsh with some coastal alkaline scrub and patchy coast banksia woodland near the coast.

Merricks Creek estuary enters Western Port near Somers, and has an entrance width that ranges from 0 to 20 m. Areas on seaward side maintain a more natural connection between the floodplain and the waterway, however flows in Merricks Creek have been reduced through the many farm dams. The estuarine reach is subject to sediment deposition, both along its length and at the creek mouth where the mouth often becomes blocked during periods of low flow, fish kills are not uncommon.

Tooradin Road Drain flows into Western Port near Tooradin. The drain has been straightened and channelised and would have historically been part of the Koo‐Wee‐Rup Swamp. Reduced lateral connectivity due to floodgate designed to protect areas from tidal inundation. Some connectivity on lower eastern banks to small patches of saltmarsh; western banks and upstream areas little to no connectivity due to levee banks and elevated landfill.

Estuarine wetland connectivity is currently very high, trending to very low; with a feasible chance of moderate
The Watson Creek estuary enters Western Port at Watsons Inlet near Somerville and flows into Yaringa Marine National Park. The channel of upper estuary well defined; limited connectivity to floodplain under high fluvial flows. Watson Inlet has relatively undisturbed mangrove (Avicennia marina) and saltmarsh habitats of State geomorphological significance. Proximity to Ramsar site. Areas of vegetation with high environmental significance occur in the estuary and adjacent floodplain to the shore of Western Port.
