6,572-acre Spencer Gulf. Sector 34 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 34 trip-scale surveyed footprint within Spencer Gulf. Australia's long western gulf, divided from upper tidal flats through major bays and channels to its offshore-facing mouth. The displayed footprint is not a legal boundary or a claim of complete named-water coverage. The water tops out around 80 ft. The depth chart comes from Geoscience Australia / AusSeabed bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The season-by-season read for each species follows, from the map's own numbers.
On the chart, Spencer Gulf - Sector 34 draws 6,572 acres inside 21 miles of shoreline. The shoreline is moderately structured (index 1.8) — enough points and pockets to pattern. Roughly 21% of the water is 15 ft or less, the band where the food chain lives. End to end it runs roughly 5.3 mi, about 2.6 mi across. Closest neighbour on DepthScout: Spencer Gulf - Sector 33, 7 mi west of here.
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 South Australian boat ramps and marine facilities 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.

Private land and private launches need the owner's permission — please ask first.
Season dates, license requirements, and size and bag limits for South Australia waters are set by the PIRSA (current recreational species limits) — and special regulations can apply to Spencer Gulf - Sector 34 specifically, so confirm the current rules before you fish. Check PIRSA's live species lookup, closures and SA Fishing app before every trip. Snapper remains absent from these page rosters because the current management closure prohibits targeting and catch-and-release in the affected South Australian waters through the stated closure period. Verify all size, boat and possession limits, protected areas, gear controls and local access directions. A contour, spot or access lead never grants fishing, retention, entry, parking or launching permission.
