66,653-acre Gunters Bay 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. Trip-scale surveyed footprint within Gunters Bay. An official Australian bay evaluated inside a compact 24-kilometre trip-planning window centred on the Composite Gazetteer feature. The public outline is limited to retained direct AusBathyTopo survey cells, not a legal or navigational boundary. The displayed footprint is not a legal boundary or a claim of complete named-water coverage. The water tops out around 62 ft. The depth chart comes from Geoscience Australia / AusSeabed bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Species by species, here's what the data says the year looks like.
Gunters Bay maps at 66,666 acres behind 70.3 miles of shoreline, with a single island in the mix. A middling shoreline index (1.9) gives it some bays to work without being a maze. Roughly 34% of the water is 15 ft or less, the band where the food chain lives. The basin spans about 18.7 mi end to end and 13.6 mi across at its widest. Its nearest charted neighbour, Burgess Bay, is 19 mi to the southeast.
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.

When the water first warms, sand flathead slide up into 8 to 35 ft. Summer is a 12 to 62 ft game here, winter an 8 to 35 ft one. Start at Deepest basin. It's a deep basin holding about 61 ft of water and rates prime come summer. The feeding windows run early morning and the evening.

|---|---|---|---|---|
| Spring | 8 to 35 ft | dawn & dusk | Shallow measured flat (7 ft) | see map |
| Summer | 12 to 62 ft | dawn & dusk | Deepest basin (61 ft) | see map |
| Fall | 8 to 56 ft | dawn & dusk | Sharp break (52 ft) | see map |
| Winter | 8 to 35 ft | dawn | Shallow measured flat (7 ft) | see map |
Spring puts black bream in skinny water — 2 to 16 ft is the zone. Warm water sends them out to 7 to 35 ft; cold water stacks them in 2 to 16 ft. Sharp break is the standout, a drop-off at roughly 34 ft, rated good for summer black bream. Plan around early morning and the evening in the warm months.

Start shallow in spring: australian salmon sit in 4 to 30 ft that time of year. Summer pushes them deeper, 11 to 62 ft, and winter fish settle into 4 to 30 ft. The spot to know is Sharp break, a drop-off in about 52 ft of water that rates prime for australian salmon in summer. Warm-month bites cluster around early morning and the evening.

Spring puts silver trevally in skinny water — 4 to 30 ft is the zone. Warm water sends them out to 11 to 62 ft; cold water stacks them in 14 to 62 ft. Sharp break is the standout, a drop-off at roughly 52 ft, rated prime for summer silver trevally. Plan around early morning and the evening in the warm months.

Spring puts gummy shark in skinny water — 8 to 40 ft is the zone. Warm water sends them out to 9 to 62 ft; cold water stacks them in 8 to 40 ft. Deepest basin is the standout, a deep basin at roughly 61 ft, rated prime for summer gummy shark. Plan around early morning and the evening in the warm months.

Early season yellowtail kingfish use the shallows, holding in 8 to 45 ft. Expect a summer slide to 10 to 62 ft, then a winter hold in 13 to 62 ft. Put Shoreline point first on the milk run — a point near 23 ft that grades prime for spring. 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 Gunters Bay 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.

Gunters Bay is about 62 ft (19 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 Gunters Bay. 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.
Deepest basin is the top-rated area: a deep basin in about 61 ft of water that rates prime for sand flathead 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.
Fishing on Gunters Bay 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.
