150,923-acre Exmouth Gulf. Sector 11 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. Sector 11 trip-scale surveyed footprint within Exmouth Gulf. A large tropical gulf with mangrove shallows, tidal channels, reefward points and deeper northern access. The displayed footprint is not a legal boundary or a claim of complete named-water coverage. The water tops out around 74 ft. The depth chart comes from Geoscience Australia / AusSeabed bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What the data behind the map says about each species, season by season:
Exmouth Gulf - Sector 11 maps at 150,922 acres behind 61.1 miles of shoreline. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline. The shallow band under 15 ft claims about 4% of the surface — that's where the groceries are. Call it 16.4 mi long by 14.5 mi wide at the broadest reach. Its nearest charted neighbour, Exmouth Gulf - Sector 12, is 12 mi to the 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.

Start shallow in spring: barramundi sit in 2 to 18 ft that time of year. They don't go far with the seasons — 2 to 18 ft covers summer, 11 to 35 ft covers winter. The spot to know is Sharp break, a drop-off in about 32 ft of water that rates good for barramundi in winter. 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 Exmouth Gulf - Sector 11 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.

Exmouth Gulf - Sector 11 is about 74 ft (23 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 Exmouth Gulf - Sector 11. 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.
Deepest basin is the top-rated area: a deep basin in about 73 ft of water that rates prime for black jewfish in winter. Every other rated spot, per species and season, is on the map above.
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.
