98,978-acre Perkins Bay. North 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. North trip-scale surveyed footprint within Perkins Bay. A broad northwest Tasmanian bay around Stanley and Smithton, with sand banks, channels and Bass Strait exchange. The displayed footprint is not a legal boundary or a claim of complete named-water coverage. The water tops out around 136 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.
The drawn water covers 98,961 acres wrapped in 54.5 miles of bank. Its 1.2 shoreline index means few bank features; the contours below do the pattern work. 2% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Figure 13.8 mi of water from one end to the other, 12.4 mi at the beam. Perkins Bay - West sits 10 mi south — 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 61 ft that scores good in summer. Best bite is 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 Perkins Bay - North 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.

Perkins Bay - North is about 136 ft (41 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, black bream, australian salmon, silver trevally, gummy shark, yellowtail kingfish roster for Perkins Bay - North. 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 61 ft of water that rates prime for australian salmon in summer. The interactive chart above rates every 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.
Fishing on Perkins Bay - North 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.
