59,332-acre Exmouth Gulf. Sector 19 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 19 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 35 ft. The depth chart comes from Geoscience Australia / AusSeabed bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here's the year, species by species, as the scoring engine sees it.
The outline encloses 59,327 acres, worked by 49.7 miles of shoreline. A middling shoreline index (1.5) gives it some bays to work without being a maze. Roughly 77% of the water is 15 ft or less, the band where the food chain lives. Figure 13.7 mi of water from one end to the other, 13.5 mi at the beam. Exmouth Gulf - Sector 15 sits 12 mi north — 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.

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 25 ft of water that rates good for barramundi in fall. 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 19 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 19 is about 35 ft (11 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.
