27,308-acre Champion Bay. Northwest 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. Northwest trip-scale surveyed footprint within Champion Bay. Geraldton's urban bay of reefs, shipping approaches, beaches and island-facing current lines. The displayed footprint is not a legal boundary or a claim of complete named-water coverage. The water tops out around 144 ft. The depth chart comes from Geoscience Australia / AusSeabed bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Species by species, here's what the data says the year looks like.
Champion Bay - Northwest maps at 27,310 acres behind 41.1 miles of shoreline. A middling shoreline index (1.8) gives it some bays to work without being a maze. Littoral water — the productive band under ~15 ft — makes up 13% of this chart. The basin spans about 13 mi end to end and 7.8 mi across at its widest. Its nearest charted neighbour, Champion Bay - Northeast, is 10 mi to the south.
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.

Early season mulloway use the shallows, holding in 5 to 30 ft. Expect a summer slide to 14 to 100 ft, then a winter hold in 18 to 100 ft. Put Sharp break first on the milk run — a drop-off near 71 ft that grades good for summer. In summer the feeding windows fall in early morning and the evening.

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 Champion Bay - Northwest 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.
