66,177-acre Vansittart 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 Vansittart 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 126 ft. The depth chart comes from Geoscience Australia / AusSeabed bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Below is the species-by-species picture, pulled from the same data the map uses.
Vansittart Bay maps at 66,176 acres behind 93.1 miles of shoreline, broken up by 2 islands. An index of 2.6 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Roughly 23% of the water is 15 ft or less, the band where the food chain lives. The basin spans about 17.6 mi end to end and 14.3 mi across at its widest. Prince Frederick Harbour sits 99 mi southwest — 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.

The spring pattern is a shallow one: barramundi in 2 to 18 ft. The depth story barely changes: 2 to 18 ft through summer, 11 to 35 ft in winter. The spot to know is Shoreline point, a point in about 4 ft of water that rates good for barramundi in spring. Plan around early morning and the evening in the warm months.

Start shallow in spring: golden snapper sit in 8 to 35 ft that time of year. They don't go far with the seasons — 8 to 35 ft covers summer, 21 to 80 ft covers winter. Top water on the chart: Sharp break, a drop-off in the 47 ft range, good in fall. Fish it in early morning and the evening and you'll meet the bite.

When the water first warms, black jewfish slide up into 8 to 35 ft. There's no big seasonal slide here — summer means 8 to 35 ft, winter 21 to 90 ft. Start at Sharp break. It's a drop-off holding about 47 ft of water and rates good come fall. The feeding windows run early morning and the evening.

The spring pattern is a shallow one: king threadfin in 2 to 16 ft. The depth story barely changes: 2 to 16 ft through summer, 10 to 35 ft in winter. The spot to know is Shallow measured flat, a feeding flat in about 4 ft of water that rates prime for king threadfin in spring. Plan around early morning and the evening in the warm months.

Early season queenfish use the shallows, holding in 3 to 25 ft. Even in summer they hold at 3 to 25 ft; winter keeps them in 15 to 55 ft. Put Sharp break first on the milk run — a drop-off near 47 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening.

The spring pattern is a shallow one: giant trevally in 4 to 30 ft. The depth story barely changes: 4 to 30 ft through summer, 18 to 80 ft in winter. The spot to know is Shoreline point, a point in about 4 ft of water that rates prime for giant trevally in spring. Plan around early morning and the evening in the warm months.

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 Vansittart 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.

Vansittart Bay is about 126 ft (38 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 barramundi, golden snapper, black jewfish, king threadfin, queenfish, giant trevally, mangrove jack, narrow-barred spanish mackerel, coral trout roster for Vansittart 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.
Shallow measured flat is the top-rated area: a feeding flat in about 4 ft of water that rates prime for king threadfin in spring. Scroll up to the map for the complete spot list by species and season.
For barramundi, 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 Vansittart 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.
