72,774-acre Hellfire Bay 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 Hellfire Bay. An official Australian bay 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 164 ft. The depth chart comes from Geoscience Australia / AusSeabed bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Every species below gets its seasonal read from the same numbers driving the chart.
On the chart, Hellfire Bay draws 72,784 acres inside 64.2 miles of shoreline. Index 1.7 on the shoreline: a few honest points and pockets, nothing labyrinthine. Roughly 4% of the water is 15 ft or less, the band where the food chain lives. End to end it runs roughly 17.5 mi, about 13.2 mi across. Closest neighbour on DepthScout: Starvation Boat Harbour, 91 mi west of here.
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. Midsummer fish sit out in 14 to 100 ft before dropping to 18 to 100 ft for winter. The spot to know is Sharp break, a drop-off in about 40 ft of water that rates good for mulloway in summer. Plan around early morning and the evening in the warm months.

Spring puts yellowtail kingfish in skinny water — 8 to 45 ft is the zone. Warm water sends them out to 20 to 130 ft; cold water stacks them in 27 to 130 ft. Shoreline point is the standout, a point at roughly 42 ft, rated prime for spring yellowtail kingfish. Plan around early morning and the evening in the warm months.

Spring tailor on Hellfire Bay hold shallow, usually 3 to 25 ft. They move out to 11 to 65 ft in summer and finish the year down in 15 to 65 ft. Put Sharp break first on the milk run — a drop-off near 40 ft that grades prime for summer. The feeding windows run early morning and the evening.

Come spring, look for silver trevally tight to the bank in 4 to 30 ft. They move out to 14 to 80 ft in summer and finish the year down in 18 to 80 ft. If you only fish one area, make it Sharp break: a drop-off around 40 ft that scores prime in summer. Best bite is 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 Hellfire Bay 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.

Hellfire Bay is about 164 ft (50 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 Hellfire Bay. 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 42 ft of water that rates prime for yellowtail kingfish in spring. The map above holds the full rated-spot list for every 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.
Fishing on Hellfire Bay 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.
