76,271-acre Great Musselroe Bay. Northwest 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. Northwest trip-scale surveyed footprint within Great Musselroe Bay. A northeast Tasmanian bay of beaches, reef points, shallow banks and exposed Bass Strait approaches. The displayed footprint is not a legal boundary or a claim of complete named-water coverage. The water tops out around 203 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.
Great Musselroe Bay - Northwest maps at 76,251 acres behind 55.9 miles of shoreline. Its 1.4 shoreline index means few bank features; the contours below do the pattern work. The shallow band under 15 ft claims about 7% of the surface — that's where the groceries are. Call it 14.9 mi long by 14.6 mi wide at the broadest reach. If the bite dies, Great Musselroe Bay - North is 12 mi to the 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.

Early season sand flathead use the shallows, holding in 8 to 35 ft. Expect a summer slide to 16 to 80 ft, then a winter hold in 8 to 35 ft. Put Sharp break first on the milk run — a drop-off near 67 ft that grades good for summer. In summer the feeding windows fall in early morning and the evening.

Start shallow in spring: black bream sit in 2 to 16 ft that time of year. Summer pushes them deeper, 7 to 35 ft, and winter fish settle into 2 to 16 ft. The spot to know is Offshore hump, an offshore hump in about 21 ft of water that rates good for black bream in summer. Warm-month bites cluster around early morning and the evening.

In spring, australian salmon run shallow here, mostly 4 to 30 ft. Midsummer fish sit out in 14 to 80 ft before dropping to 4 to 30 ft for winter. Summer australian salmon concentrate at Sharp break, a prime-rated drop-off around 67 ft. Fish it in early morning and the evening and you'll meet the bite.

Start shallow in spring: silver trevally sit in 4 to 30 ft that time of year. Summer pushes them deeper, 14 to 80 ft, and winter fish settle into 18 to 80 ft. The spot to know is Sharp break, a drop-off in about 67 ft of water that rates prime for silver trevally in summer. Warm-month bites cluster around early morning and the evening.

Start shallow in spring: gummy shark sit in 8 to 40 ft that time of year. Summer pushes them deeper, 18 to 120 ft, and winter fish settle into 8 to 40 ft. The spot to know is Sharp break, a drop-off in about 110 ft of water that rates prime for gummy shark in summer. Warm-month bites cluster around early morning and the evening.

Come spring, look for yellowtail kingfish tight to the bank in 8 to 45 ft. They move out to 20 to 130 ft in summer and finish the year down in 27 to 130 ft. If you only fish one area, make it Shoreline point: a point around 23 ft that scores prime in spring. 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 Great Musselroe Bay - Northwest 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.

Great Musselroe Bay - Northwest is about 203 ft (62 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 Great Musselroe Bay - Northwest. 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 67 ft of water that rates prime for australian salmon in summer. The map above holds the full rated-spot list for every 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.
