24,205-acre Western Port. Southwest Australian saltwater fishing map showing only directly measured AusBathyTopo 2026 cells, source-qualified fishing spots, official regional fish evidence, seasonal forage context, access guidance and current-rule links. Southwest trip-scale surveyed footprint within Western Port. A tidal bay of branching channels, extensive flats, islands and high-current ocean entrances. The displayed footprint is not a legal boundary or a claim of complete named-water coverage. The water tops out around 184 ft. The depth chart comes from Geoscience Australia / AusSeabed bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The rest of this page walks each species through its year, using the map's own scoring.
The drawn water covers 24,206 acres wrapped in 43.7 miles of bank. A middling shoreline index (2) gives it some bays to work without being a maze. The shallow band under 15 ft claims about 12% of the surface — that's where the groceries are. Call it 12.4 mi long by 7.2 mi wide at the broadest reach. If the bite dies, Western Port - West is 6 mi to the north.
Regional occurrence does not mean equal abundance, child-specific catch rate, retention permission or a promised catch. Live state, territory, Commonwealth, protected-area and local rules always control. The roster may combine exact-water monitoring with habitat-filtered official regional evidence; it does not imply that every species is equally abundant throughout the mapped section.

No facility from the cited Victorian recreational boating facilities source was spatially attached within 3 km of this directly measured map footprint during the 2026-09-08 audit. This is an evidence gap, not a claim that public access is absent.

Private land and private launches need the owner's permission — please ask first.
Season dates, license requirements, and size and bag limits for Victoria waters are set by the Victorian Fisheries Authority (current recreational-fishing guide) — and special regulations can apply to Western Port - Southwest specifically, so confirm the current rules before you fish. Check the live Victorian recreational-fishing guide and licence requirements before every trip. Size and possession limits, closed seasons and waters, marine parks, protected species, permitted equipment and local port or council directions may all apply. A directly measured bathymetry footprint, fishing-spot marker or nearby access lead is planning context only; it never grants fishing, retention, entry, parking or launching permission.
