34,034-acre Starvation Boat Harbour 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. Trip-scale surveyed footprint within Starvation Boat Harbour. An official Australian harbour evaluated inside a compact 24-kilometre trip-planning window centred on the Composite Gazetteer feature. The public outline is limited to retained direct AusBathyTopo survey cells, not a legal or navigational boundary. The displayed footprint is not a legal boundary or a claim of complete named-water coverage. The water tops out around 117 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.
Traced from the shoreline, Starvation Boat Harbour runs 34,031 acres with 44.1 miles of edge. Index 1.7 on the shoreline: a few honest points and pockets, nothing labyrinthine. Littoral water — the productive band under ~15 ft — makes up 12% of this chart. End to end it runs roughly 16.5 mi, about 5.5 mi across. For a second option, Hellfire Bay lies 91 mi east.
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.

The spring pattern is a shallow one: mulloway in 5 to 30 ft. As the season builds they drop to 14 to 100 ft, wintering in 18 to 100 ft. Top water on the chart: Sharp break, a drop-off in the 50 ft range, good in summer. Time it for early morning and the evening.

Spring puts yellowtail kingfish in skinny water — 8 to 45 ft is the zone. As the season builds they drop to 18 to 117 ft, wintering in 24 to 117 ft. Spring yellowtail kingfish concentrate at Shoreline point, a prime-rated point around 37 ft. Warm-month bites cluster around early morning and the evening.

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. Check the official portal, live site signs, tides, ramp condition, vessel suitability, fees, parking, working-port restrictions and landowner permissions before travel: https://catalogue.data.wa.gov.au/dataset/boat-ramps
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 Starvation Boat Harbour 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.

Starvation Boat Harbour is about 117 ft (36 m) deep at its deepest point. The depth chart comes from Geoscience Australia / AusSeabed bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Official coastal monitoring from Western Australia Department of Primary Industries and Regional Development regional evidence informs the mulloway, yellowtail kingfish, tailor, silver trevally, gummy shark, king george whiting roster for Starvation Boat Harbour. The mixed roster combines exact-water records where available with habitat-filtered regional evidence; not every species is documented at this exact water, and it is not a promise of equal abundance or a catch on a particular trip.
Shoreline point is the top-rated area: a point in about 37 ft of water that rates prime for yellowtail kingfish in spring. Every other rated spot, per species and season, is on the map above.
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.
Fishing on Starvation Boat Harbour is regulated by the WA DPIRD (current recreational-fishing rules). Check the official Western Australia regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
