64,055-acre Hamelin 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 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 249 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.
Drawn out, this is 64,054 acres of water rimmed by 39.7 miles of bank. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline. Roughly 1% of the water is 15 ft or less, the band where the food chain lives. End to end it runs roughly 10.7 mi, about 10.4 mi across. For a second option, Hamelin Bay - West lies 7 mi southeast.
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.

Access data: Western Australia Department of Transport Public Boat Ramps (DOT-033). Confirm conditions and fees locally before you launch.
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 - Northeast 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.
