Tasmania East Coast Fishing — A Complete Guide
Tasmania East Coast fishing — St Helens, Eaglehawk Neck, Hobart. Southern bluefin tuna, striped marlin, mako shark, flathead, calamari. Seasonal calendar + spots.
Tasmania's east coast — from St Helens in the north to Eaglehawk Neck and Hobart in the south — has the best of AU's southern game fishing. Southern bluefin tuna run hard Apr–Jul, striped marlin show in summer (a southern range record), and mako sharks are reliable year-round. Inshore: world-class calamari, flathead, snapper at the northern range, and rock-fishing for trumpeter + morwong.
The geography
- East Australian Current extension: EAC water reaches Tasmania in summer + autumn — the southern range of warm-water species. Tasman Sea on the east side.
- Continental shelf: Sits 15–40 km offshore. Drop-off to deep water close in.
- Major ports: St Helens (north-east), Bicheno, Triabunna, Eaglehawk Neck (Tasman Peninsula), Hobart (Derwent estuary).
- Tasman Peninsula: Premium SBT + game-fishing zone with deep water close in (10 km).
Top species + when they bite
- Southern Bluefin Tuna — Apr–Jul. Eaglehawk Neck + St Helens. Iconic TAS fishery.
- Striped Marlin — Summer (Dec–Mar). Southern range; St Helens area.
- Yellowfin Tuna — Summer pulses on EAC extension. Less reliable than SBT.
- Mako Shark — Year-round. Berley specialists. Eaglehawk Neck reliable.
- Albacore — Convergence-front fish. Late summer + autumn.
- Flathead — Iconic TAS species. Sand flats + bays. Year-round.
- Calamari (Squid) — World-class TAS calamari. Year-round on jigs.
- Snapper (northern range) — Northern + east coast in summer; warm-water visitor.
- Striped Trumpeter + Morwong — Reef fish. Bottom + rock-fishing.
Famous spots
- Eaglehawk Neck (Tasman Peninsula) — Premier SBT + striped marlin water; deep water 10 km offshore.
- St Helens — Northeast TAS; SBT + mako + striped marlin in summer.
- The Hippolyte Rocks (off Tasman Peninsula) — Iconic offshore stack; bottom + game fish.
- Maria Island — Sheltered fishing for flathead + bottom + calamari.
- Storm Bay (Hobart) — Wide bay south of Hobart; tuna + flathead + calamari.
- Bicheno reefs — Mid-east coast bottom + snapper grounds.
- St Helens shelf break — Deep water close in; SBT + mako.
Conditions to watch
Cool-temperate to cold conditions — water 11–19°C through the year. Westerlies dominant; the famous Roaring Forties bring sustained heavy weather. Tasman Sea past the shelf is open ocean — sea state can build very fast. East coast is more sheltered than the west but check forecasts carefully. Whale season + abundant marine wildlife requires care + distance.
Reading BiteCast for Tasmania East Coast
- SST (sea-surface temperature) — SBT specialists: 14–18°C is the working band Apr–Jul. Filter for sharp temperature breaks.
- Altimetry + Eddies — EAC extension eddies arrive in summer + autumn. Warm-core eddy edges = pelagic stack.
- Subsurface temperature — 100 m subsurface critical for SBT trolling depth.
- Chlorophyll — Productivity edges off shelf hold baitfish + SBT.

Frequently asked
When is the Tasmania SBT season?
April through July is the recognised window with peak in May–June. Eaglehawk Neck and St Helens are the recognised hubs. Fish are typically 40–80 kg with bigger fish 100+ kg in good years. Most serious SBT fishing is charter-based.
Can you really catch striped marlin in Tasmania?
Yes — Tasmania's east coast (St Helens area) is the southern recognised range for striped marlin. Summer (Dec–Mar) when EAC extension water pushes south. Numbers are lower than Sydney/Bermagui but the Tasmania captures are special precisely because they're the southern edge.
What's the rock-fishing scene like in Tasmania?
Excellent — the rocky coastline holds striped trumpeter, morwong, wrasse, blackback salmon, and calamari. Always check rock-fishing safety advice; the southern coast is exposed and people die from being washed off rocks every year.
Where is the Hippolyte Rocks?
Iconic offshore stack ~10 km east of the Tasman Peninsula near Eaglehawk Neck. Bottom fishing for striped trumpeter, snapper, morwong; surface fishing for SBT + striped marlin in season. Charter-only access for most.
