7,781-acre King Sound. Sector 29 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 29 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 36 ft. The depth chart comes from Geoscience Australia / AusSeabed bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Every species below gets its seasonal read from the same numbers driving the chart.
On the chart, King Sound - Sector 29 draws 7,781 acres inside 19.6 miles of shoreline. The shoreline is moderately structured (index 1.6) — enough points and pockets to pattern. Littoral water — the productive band under ~15 ft — makes up 51% of this chart. Figure 6.3 mi of water from one end to the other, 3.4 mi at the beam. The nearest mapped water is King Sound - Sector 22, 9 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.

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 29 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 29 is about 36 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.
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 King Sound - Sector 29. 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 34 ft of water that rates prime for black jewfish in fall. Open the map above to see every rated spot for each 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.
