9,924-acre Storm Bay. Sector 04 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 04 trip-scale surveyed footprint within Storm Bay. The exposed bay south of Hobart connecting the Derwent, D'Entrecasteaux Channel and Tasman Peninsula. The displayed footprint is not a legal boundary or a claim of complete named-water coverage. The water tops out around 325 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.
Storm Bay - Sector 04 maps at 9,924 acres behind 51.1 miles of shoreline. That shoreline is heavily fingered (development index 3.7) — bays, points and pockets everywhere, which multiplies the fishable edge. Littoral water — the productive band under ~15 ft — makes up 11% of this chart. Figure 15.4 mi of water from one end to the other, 4.3 mi at the beam. Great Oyster Bay - Sector 10 sits 17 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.

Come spring, look for sand flathead tight to the bank in 8 to 35 ft. They move out to 16 to 80 ft in summer and finish the year down in 8 to 35 ft. If you only fish one area, make it Sharp break: a drop-off around 60 ft that scores good in summer. Best bite is early morning and the evening.

The spring pattern is a shallow one: australian salmon in 4 to 30 ft. As the season builds they drop to 14 to 80 ft, wintering in 4 to 30 ft. Top water on the chart: Sharp break, a drop-off in the 60 ft range, prime in summer. Time it for early morning and the evening.

No facility from the cited Marine and Safety Tasmania boating 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 Tasmania waters are set by the Fishing Tasmania (current recreational sea-fishing rules) — and special regulations can apply to Storm Bay - Sector 04 specifically, so confirm the current rules before you fish. Check Fishing Tasmania's live sea-fishing rules and licensing pages before every trip. Current species limits, licences for particular fisheries, seasonal and area closures, marine reserves, protected species, gear controls and biosecurity measures may apply. A directly measured depth footprint, fishing-spot marker or access lead is planning context only and never grants permission to fish, keep catch, enter private or port land, park or launch.

Storm Bay - Sector 04 is about 325 ft (99 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 Tasmania Department of Natural Resources and Environment regional evidence informs the sand flathead, australian salmon, silver trevally, gummy shark, yellowtail kingfish roster for Storm Bay - Sector 04. 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.
Sharp break is the top-rated area: a drop-off in about 60 ft of water that rates prime for australian salmon in summer. Open the map above to see every rated spot for each species and season.
For sand flathead, 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.
