15,257-acre Storm Bay. Sector 10 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 10 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 293 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, Storm Bay - Sector 10 draws 15,258 acres inside 58.1 miles of shoreline. With a shoreline index of 3.4, this water is all arms and coves — edge habitat well beyond its acreage. Roughly 6% of the water is 15 ft or less, the band where the food chain lives. Call it 15.1 mi long by 3.5 mi wide at the broadest reach. For a second option, Storm Bay - Sector 11 lies 11 mi east.
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.
| Species | Evidence basis | Count / date |
|---|---|---|
| sand flathead (Sand Flathead) | official species listing | — |
| gummy shark (Gummy Shark) | official species listing | — |
Official species-evidence source.
In spring, sand flathead run shallow here, mostly 8 to 35 ft. Midsummer fish sit out in 16 to 80 ft before dropping to 8 to 35 ft for winter. Fish it in early morning and the evening and you'll meet the bite.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 35 ft | dawn & dusk | open water | see map |
| Summer | 16 to 80 ft | dawn & dusk | open water | see map |
| Fall | 8 to 56 ft | dawn & dusk | open water | see map |
| Winter | 8 to 35 ft | dawn | open water | see map |
Early season gummy shark use the shallows, holding in 8 to 40 ft. Expect a summer slide to 18 to 120 ft, then a winter hold in 8 to 40 ft. Put Sharp break first on the milk run — a drop-off near 142 ft that grades good for summer. In summer the feeding windows fall in 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. Check the official portal, live site signs, tides, ramp condition, vessel suitability, fees, parking, working-port restrictions and landowner permissions before travel: https://mast.tas.gov.au/recreational/boating-facilities/
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 10 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 10 is about 293 ft (89 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, gummy shark roster for Storm Bay - Sector 10. 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 142 ft of water that rates good for gummy shark in summer. Every other rated spot, per species and season, is on the map above.
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.
Fishing on Storm Bay - Sector 10 is regulated by the Fishing Tasmania (current recreational sea-fishing rules). Check the official Tasmania regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
