20,960-acre Portland Bay. Northeast 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. Northeast trip-scale surveyed footprint within Portland Bay. A southwest Victorian bay with harbor walls, reefs, beach contours and exposed Southern Ocean approaches. The displayed footprint is not a legal boundary or a claim of complete named-water coverage. The water tops out around 176 ft. The depth chart comes from Geoscience Australia / AusSeabed bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What follows comes from the same scoring engine that paints the spots above.
Traced from the shoreline, Portland Bay - Northeast runs 20,960 acres with 37.3 miles of edge. The shoreline is moderately structured (index 1.8) — enough points and pockets to pattern. Littoral water — the productive band under ~15 ft — makes up 13% of this chart. Call it 11.1 mi long by 5.6 mi wide at the broadest reach. For a second option, Portland Bay - West lies 7 mi east.
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.

Spring puts australasian snapper in skinny water — 6 to 35 ft is the zone. Warm water sends them out to 16 to 120 ft; cold water stacks them in 21 to 120 ft. Sharp break is the standout, a drop-off at roughly 67 ft, rated prime for summer australasian snapper. Plan around early morning and the evening in the warm months.

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.

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 Portland Bay - Northeast 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.
