58,824-acre Hanover 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 Hanover 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 337 ft. The depth chart comes from Geoscience Australia / AusSeabed bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here is how the season plays out for each species, straight from the data behind the map.
Traced from the shoreline, Hanover Bay runs 58,815 acres with 112.8 miles of edge — 2 islands included. The 3.3 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. The shallow band under 15 ft claims about 14% of the surface — that's where the groceries are. Figure 18.1 mi of water from one end to the other, 12.2 mi at the beam. The nearest mapped water is Prince Frederick Harbour, 35 mi to the northeast.
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.

Come spring, look for barramundi tight to the bank in 2 to 18 ft. Through summer count on 2 to 18 ft; the winter hold is 11 to 35 ft. If you only fish one area, make it Sharp break: a drop-off around 30 ft that scores good in winter. Best bite is early morning and the evening.

When the water first warms, golden snapper slide up into 8 to 35 ft. There's no big seasonal slide here — summer means 8 to 35 ft, winter 21 to 80 ft. Start at Sharp break. It's a drop-off holding about 30 ft of water and rates good come fall. The feeding windows run early morning and the evening.

Start shallow in spring: black jewfish 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 90 ft covers winter. Top water on the chart: Sharp break, a drop-off in the 30 ft range, good in fall. Fish it in early morning and the evening and you'll meet the bite.

Come spring, look for king threadfin tight to the bank in 2 to 16 ft. Through summer count on 2 to 16 ft; the winter hold is 10 to 35 ft. If you only fish one area, make it Sharp break: a drop-off around 30 ft that scores good in winter. Best bite is early morning and the evening.

In spring, queenfish run shallow here, mostly 3 to 25 ft. Summer keeps them at 3 to 25 ft, and they winter in 15 to 55 ft. Sharp break is the standout, a drop-off at roughly 30 ft, rated prime for fall queenfish. Time it for 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 Hanover 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.

Hanover Bay is about 337 ft (103 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 Hanover 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.
Sharp break is the top-rated area: a drop-off in about 30 ft of water that rates prime for queenfish in fall. 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 Hanover 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.
