11,218-acre King Sound. Sector 27 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 27 trip-scale surveyed footprint within King Sound. A strongly tidal Kimberley sound of island passages, turbid channels, mud banks and river-fed southern arms. The displayed footprint is not a legal boundary or a claim of complete named-water coverage. The water tops out around 76 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:
Drawn out, this is 11,217 acres of water rimmed by 39.1 miles of bank. That shoreline is heavily fingered (development index 2.6) — bays, points and pockets everywhere, which multiplies the fishable edge. The basin spans about 12.2 mi end to end and 3.9 mi across at its widest. For a second option, King Sound - Sector 28 lies 14 mi southeast.
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.

When the water first warms, barramundi slide up into 2 to 18 ft. There's no big seasonal slide here — summer means 2 to 18 ft, winter 11 to 35 ft. Start at Sharp break. It's a drop-off holding about 11 ft of water and rates good come fall. The feeding windows run early morning and the evening.

Come spring, look for golden snapper tight to the bank in 8 to 35 ft. Through summer count on 8 to 35 ft; the winter hold is 20 to 76 ft. If you only fish one area, make it Sharp break: a drop-off around 11 ft that scores good in fall. Best bite is early morning and the evening.

The spring pattern is a shallow one: black jewfish in 8 to 35 ft. The depth story barely changes: 8 to 35 ft through summer, 18 to 76 ft in winter. The spot to know is Sharp break, a drop-off in about 11 ft of water that rates good for black jewfish in fall. Plan around early morning and the evening in the warm months.

Spring puts queenfish in skinny water — 3 to 25 ft is the zone. Summer fish stay in 3 to 25 ft, and winter fish hold in 15 to 55 ft. Fall queenfish concentrate at Sharp break, a prime-rated drop-off around 11 ft. 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 King Sound - Sector 27 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.

King Sound - Sector 27 is about 76 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.
