64,342-acre Geographe Bay. Sector 13 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 13 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 186 ft. The depth chart comes from Geoscience Australia / AusSeabed bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here's the year, species by species, as the scoring engine sees it.
Geographe Bay - Sector 13 maps at 64,355 acres behind 80.2 miles of shoreline — one island included. An index of 2.3 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. 6% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. The basin spans about 18.9 mi end to end and 13.7 mi across at its widest. Hamelin Bay - Northwest sits 12 mi south — the closest neighbouring chart.
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 mulloway on Geographe Bay - Sector 13 hold shallow, usually 5 to 30 ft. They move out to 14 to 100 ft in summer and finish the year down in 18 to 100 ft. Put Sharp break first on the milk run — a drop-off near 63 ft that grades good for summer. The feeding windows run 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 13 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.

Shoreline point is the top-rated area: a point in about 21 ft of water that rates prime for yellowtail kingfish in spring. Scroll up to the map for the complete spot list by species and season.
For mulloway, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
