8,196-acre Hamelin Bay. West 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. West trip-scale surveyed footprint within Hamelin Bay. A compact southwest bay with reefs, sand, historic jetty structure and exposed Indian Ocean swell. The displayed footprint is not a legal boundary or a claim of complete named-water coverage. The water tops out around 102 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.
The outline encloses 8,197 acres, worked by 16.5 miles of shoreline. Its 1.3 shoreline index means few bank features; the contours below do the pattern work. 10% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Figure 6.2 mi of water from one end to the other, 3.7 mi at the beam. Its nearest charted neighbour, Hamelin Bay - Northeast, is 7 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.

No facility from the cited Western Australia Department of Transport Public Boat Ramps (DOT-033) 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 Western Australia waters are set by the WA DPIRD (current recreational-fishing rules) — and special regulations can apply to Hamelin Bay - West specifically, so confirm the current rules before you fish. Check WA DPIRD's live regional guide, licences, demersal-management measures, species limits, seasonal and spatial closures, marine parks, protected species and permitted gear before every trip. Species available to target can change by bioregion and date; a regional occurrence record is not an open-season signal. A directly measured contour, fishing spot or access lead never grants fishing, retention, port entry, parking or launching permission.
