25,956-acre Geographe Bay. Sector 09 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. Sector 09 trip-scale surveyed footprint within Geographe Bay. A broad southwest-facing bay with long sand flats, seagrass, artificial structure and headland transitions. The displayed footprint is not a legal boundary or a claim of complete named-water coverage. The water tops out around 159 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.
Traced from the shoreline, Geographe Bay - Sector 09 runs 25,953 acres with 57.7 miles of edge. An index of 2.6 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. 9% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. The basin spans about 15.6 mi end to end and 5.3 mi across at its widest. The nearest mapped water is Geographe Bay - Sector 05, 13 mi to the north.
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.

In spring, mulloway run shallow here, mostly 5 to 30 ft. Summer pushes them deeper, 14 to 100 ft, and winter fish settle into 18 to 100 ft. Sharp break is the standout, a drop-off at roughly 80 ft, rated good for summer mulloway. Time it for early morning and the evening.

Start shallow in spring: yellowtail kingfish sit in 8 to 45 ft that time of year. Summer pushes them deeper, 20 to 130 ft, and winter fish settle into 27 to 130 ft. The spot to know is Shoreline point, a point in about 35 ft of water that rates prime for yellowtail kingfish in spring. Warm-month bites cluster around 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 Geographe Bay - Sector 09 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.
