7,969-acre Western Port. Southeast 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. Southeast 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 110 ft. The depth chart comes from Geoscience Australia / AusSeabed bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here is how the season plays out for each species, straight from the data behind the map.
Western Port - Southeast maps at 7,969 acres behind 28.8 miles of shoreline. That shoreline is heavily fingered (development index 2.3) — bays, points and pockets everywhere, which multiplies the fishable edge. About 29% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. End to end it runs roughly 11.1 mi, about 2.9 mi across. Its nearest charted neighbour, Western Port - South, is 10 mi to the northwest.
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.

When the water first warms, australasian snapper slide up into 6 to 35 ft. Summer is a 15 to 110 ft game here, winter a 19 to 110 ft one. Start at Sharp break. It's a drop-off holding about 65 ft of water and rates prime come summer. The feeding windows run early morning and the evening.

When the water first warms, king george whiting slide up into 3 to 18 ft. By summer they slide out to 8 to 45 ft, and by winter most fish are in 11 to 45 ft. If you only fish one area, make it Sharp break: a drop-off around 24 ft that scores good in summer. In summer the feeding windows fall in early morning and the evening.

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 - Southeast 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.

Western Port - Southeast is about 110 ft (34 m) deep at its deepest point. The depth chart comes from Geoscience Australia / AusSeabed bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Official coastal monitoring from Victorian Fisheries Authority regional evidence informs the australasian snapper, king george whiting, sand flathead, black bream, australian salmon, silver trevally, gummy shark, yellowtail kingfish roster for Western Port - Southeast. The mixed roster combines exact-water records where available with habitat-filtered regional evidence; not every species is documented at this exact water, and it is not a promise of equal abundance or a catch on a particular trip.
Sharp break is the top-rated area: a drop-off in about 65 ft of water that rates prime for australasian snapper in summer. The interactive chart above rates every spot for each species and season.
