18,466-acre Western Port. South 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. South 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 109 ft. The depth chart comes from Geoscience Australia / AusSeabed bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Western Port - South runs 18,465 acres with 48.1 miles of edge. The 2.5 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Littoral water — the productive band under ~15 ft — makes up 55% of this chart. The basin spans about 12 mi end to end and 7 mi across at its widest. For a second option, Western Port - Central lies 8 mi 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.

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 - South 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.
