The Thrill of the Chase: Southern Bluefin Tuna
Catching Southern Bluefin Tuna (SBT) offers one of Australia’s most electrifying offshore fishing experiences. From Portland and Port Fairy in Victoria to Robe and Port MacDonnell in South Australia, these oceanic predators keep reels screaming and hearts pounding.
🌊 Where to Find Them
Southwest Victoria: Famed barrel tuna hunts near Port Fairy and Portland peak in late autumn and winter.
South Australia: For catching Southern Bluefin Tuna. Early season hotspots like Robe and Port MacDonnell fire up when warm currents draw bait inshore.
SBT can be found close to headlands (20–30m) or beyond the shelf, depending on current lines and bait movement.
🔍 Finding Tuna
Monitor sea surface temperature (SST) charts and bait-rich eddies.
Watch for diving birds, bait balls, sonar arches, and surface boils.
If nothing’s showing, start trolling a spread of skirted and diving lures to locate fish.
🛥️ Trolling Tactics
Use 6–8 ft medium to heavy-action rods paired with 20–37kg trolling outfits.
Run a 5–6 lure spread: skirts, deep divers, bibbed minnows, and stickbaits.
Troll around headland drop-offs, bait schools, and shelf contours for best results.
🎯 Alternative Methods
Lure Casting: Effective when fish are busting on top. Cast stickbaits or sub-surface minnows.
Cubing: Use cut pilchards in a slick, drifting unweighted baits through the trail.
Jigging: Drop metal jigs into sonar-marked schools for fast vertical action.
🎣 Gear Tip
School-Size Tuna:
Spin reel (5000–8000), 30 lb braid, 40–60 lb fluorocarbon leader
Barrel Tuna:
80–130 lb mono or braid, wind-on leaders, quality crimped rigs
Use gimbal belts and harnesses to manage long battles
🚨 Water Safety & Offshore Awareness
Heading offshore in pursuit of SBT is incredibly rewarding, but it’s not without its risks. Here’s how to stay safe on the Southern Ocean:
✅ Safety Essentials
Life Jackets: Wear them at all times—conditions can change quickly.
EPIRB: A registered, GPS-equipped EPIRB is a non-negotiable for offshore trips.
Marine Radio: Keep a working VHF radio to contact Coast Guard or other vessels in an emergency.
PLBs (Personal Locator Beacons): Great for deckies or solo crew in case of man-overboard.
🌊 Plan & Prepare
Check weather forecasts and tides—monitor wind speed and swell height closely.
Always log on with Marine Rescue and tell someone onshore your expected return time.
Ensure your vessel has reliable GPS, sonar, and enough fuel (and backup) to return safely.
🧰 Smart Extras when out catching Southern Bluefin Tuna
Bring extra layers, waterproof gear, and sun protection.
Carry a first aid kit, fresh water, and dry bags for comms and electronics.
Invest in a quality sea anchor or drogue for stability in rough water if motor fails.
🧠 Bonus Tip: Stay Mobile & Observant
Some days SBT are 5km off Port Fairy, others they’re 40km out past Robe. Flexibility is key—watch the signs and don’t hesitate to move if things are quiet.
