40,582-acre Alexandra 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 Alexandra 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 102 ft. The depth chart comes from Geoscience Australia / AusSeabed bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The season-by-season read for each species follows, from the map's own numbers.
Drawn out, this is 40,578 acres of water rimmed by 45.4 miles of bank. The shoreline is moderately structured (index 1.6) — enough points and pockets to pattern. The shallow band under 15 ft claims about 4% of the surface — that's where the groceries are. Tip to tip the water measures near 15.9 mi with a 6.8-mi widest point. Closest neighbour on DepthScout: Cedar Bay, 25 mi north 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.

Early season barramundi use the shallows, holding in 2 to 18 ft. Even in summer they hold at 2 to 18 ft; winter keeps them in 11 to 35 ft. The chart's best answer is Shoreline point — point, 7 ft, good for spring. Best bite is early morning and the evening.

Spring golden snapper on Alexandra Bay hold shallow, usually 8 to 35 ft. Depth-wise the year is flat: 8 to 35 ft in summer, 21 to 80 ft once it turns cold. Put Sharp break first on the milk run — a drop-off near 67 ft that grades good for winter. The feeding windows run early morning and the evening.

In spring, black jewfish run shallow here, mostly 8 to 35 ft. Summer keeps them at 8 to 35 ft, and they winter in 21 to 90 ft. Winter black jewfish concentrate at Sharp break, a good-rated drop-off around 82 ft. Fish it in early morning and the evening and you'll meet the bite.

Early season king threadfin use the shallows, holding in 2 to 16 ft. Even in summer they hold at 2 to 16 ft; winter keeps them in 10 to 35 ft. The chart's best answer is Shoreline point — point, 7 ft, good for spring. Best bite is early morning and the evening.

The spring pattern is a shallow one: queenfish in 3 to 25 ft. The depth story barely changes: 3 to 25 ft through summer, 15 to 55 ft in winter. Top water on the chart: Shoreline point, a point in the 7 ft range, good in spring. Time it for early morning and the evening.

Early season giant trevally use the shallows, holding in 4 to 30 ft. Even in summer they hold at 4 to 30 ft; winter keeps them in 18 to 80 ft. The chart's best answer is Shoreline point — point, 7 ft, prime for spring. Best bite is early morning and the evening.

No facility from the cited Queensland recreational boating facilities 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.

Private land and private launches need the owner's permission — please ask first.
Season dates, license requirements, and size and bag limits for Queensland waters are set by the Queensland Government (current recreational-fishing rules) — and special regulations can apply to Alexandra Bay specifically, so confirm the current rules before you fish. Check Queensland's live tidal-water size and possession limits, closed seasons and closed waters before every trip. During a closed season, official guidance can prohibit targeting a species even for catch-and-release. Also verify marine-park zoning, protected and no-take species, gear rules, bait-movement controls and local access directions. A mapped survey footprint or fishing spot is not legal permission to fish, retain catch, enter, park or launch.

Alexandra Bay is about 102 ft (31 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 Queensland Department of Primary Industries regional evidence informs the barramundi, golden snapper, black jewfish, king threadfin, queenfish, giant trevally, mangrove jack, narrow-barred spanish mackerel, coral trout roster for Alexandra 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 7 ft of water that rates prime for giant trevally in spring. The map above holds the full rated-spot list for every 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 Alexandra Bay is regulated by the Queensland Government (current recreational-fishing rules). Check the official Queensland regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
