Fishing Outer Harbor & North Haven
The local marine system is driven by strong tidal currents flushing out of the Port River, pushing rich bait schools past the rock breakwaters into Gulf St Vincent. Summer and autumn deliver explosive action for trophy Mulloway, Sand Flathead, Blue Swimmer Crabs, and Silver Trevally. Note that under 2026 PIRSA regulations, Southern Calamari and Garfish are closed in Gulf St Vincent until April 2027, and Snapper remains under a strict zero-retention (0-bag) closure.
Land-based fishers can work the massive Outer Harbor breakwall, North Haven marina rock walls, and Snagger Point. Soaking whole pilchards or live mullet on heavy running setups from the breakwall pulls trophy Mulloway, Sand Flathead, and Gummy Sharks. Dropping light bait rigs beside Port River pylons yields Silver Trevally, Tommy Ruff, and Black Bream.
Boaters launching from Outer Harbor Boat Ramp or North Haven Boat Ramp enjoy high-capacity multi-lane facilities protected by breakwaters. Trolling shallow-diving minnow lures around the Port River entrance markers targets Australian Salmon, Snook, and sea-run fish. Heading out to the 8 to 12-meter depth lines off the Semaphore artificial reefs yields limits of Sand Flathead and Silver Trevally.
Top 10 Species
Landbased
- OUTER HARBOR BREAKWALL: Massive granite rock breakwater extending into deep shipping channel waters. Cast 28g metal spinners into current seams for Australian Salmon and Snook. Soaking whole pilchards or fresh mullet on heavy bottom setups pulls trophy Mulloway, Sand Flathead, and Gummy Sharks.
- NORTH HAVEN MARINA BREAKWALL: Sheltered rock wall protecting the marina entrance offering deep casting into tidal currents. Cast 28g to 40g metal spinners or white soft plastics far out into current seams for Australian Salmon and Snook. Sturdy non-slip footwear and caution are required near granite boulders.
- SNAGGER POINT FORESHORE: Rocky outcrop near the harbour mouth featuring clear sand gaps and ribbon weed. Wader fishers cast fresh ghost shrimp or cockles on light running sinker rigs into sandy gutters for Yellowfin Whiting and Sand Flathead. Early morning high tides before boat traffic increases deliver active bites.
- PORT RIVER MOUTH JETTY: Industrial timber jetty structure sitting over deep estuarine current. Drop light patternoster rigs baited with peeled prawns beside pylons for Silver Trevally, Tommy Ruff, and Black Bream. High water flow brings fish tight against the structure to ambush moving bait.
- LARGS BAY JETTY: Historic timber jetty located just south of North Haven extending over shallow sand flats. Drop light patternoster rigs baited with peeled prawns or cockles for Silver Trevally and Tommy Ruff. Wader fishers working the surrounding sandbars pull legal Sand Flathead.
Offshore
- SEMAPHORE ARTIFICIAL REEFS: Purpose-built concrete reef modules sitting in 8 to 12 meters depth off Outer Harbor. Drift or anchor over the structure casting soft plastics or live bait rigs for Mulloway, Silver Trevally, and King George Whiting. Using high-definition fishfinders helps pinpoint tight schools holding over the modules.
- PORT RIVER DREDGED CHANNEL: Deep commercial shipping channel reaching 12 to 20 meters depth leading into the port. Set heavy anchors on the channel slope at night with fresh fish fillets or whole fish heads for large Gummy Sharks and Mulloway. Heavy running sinker rigs are required against strong tidal flow.
- NORTH HAVEN WEED MEADOWS: Wide shallow basin holding dense submerged ribbon weed in 3 to 8 meters depth. Drift across clear sand gaps casting light whiting rigs baited with fresh ghost shrimp for Sand Flathead and Yellowfin Whiting. Clear water days with light winds deliver ideal conditions.
- OUTER GULF CRAB FLATS: Vast shallow mud and sand flats sitting in 2 to 6 meters depth across Gulf St Vincent. Drop crab net hoops baited with fish frames in clear sand channels for Blue Swimmer Crabs during summer. The clear water over sand gaps also yields consistent Sand Flathead.
- BARKER INLET ENTRANCE BAR: Shallow sandbar drop-off straight outside the river entrance dropping into 5 meters depth. Slow-troll small 60mm shallow-diving minnows or pitch micro soft-vibes along outer clay bends for Sand Flathead and Australian Salmon. Keep your lure swimming close to bottom clay ledges.

Local Bait Tips
