Fishing Marion Bay & Innes National Park
The regional marine environment is driven by heavy Southern Ocean swells and cold upwellings that wash towering limestone sea cliffs. Summer and autumn bring explosive action for Yellowtail Kingfish, Samson Fish, Southern Calamari, and Sand Flathead. The wild ocean beaches of Pondalowie and Browns Beach produce Australia's finest land-based Australian Salmon fishing.
Land-based fishers can work Marion Bay Jetty, Stenhouse Bay jetty, and national park surf beaches. Casting size 3.0 or 3.5 squid jigs off Marion Bay Jetty yields top-quality Southern Calamari. Setting up heavy surf rod stands on Browns Beach using 40g to 60g metal spinners or whole pilchards on ganged hooks pulls massive Australian Salmon.
Boaters launching from Marion Bay Boat Ramp or Pondalowie Bay Ramp enjoy direct access to Investigator Strait and the Wedge Island group. Trolling large skirted lures or slow-boating live baits around Cape Spencer targets trophy Yellowtail Kingfish and Samson Fish. Heading out to the 30 to 60-meter deep marks off Althorpe Islands produces outstanding Nannygai, Striped Trumpeter, and Gummy Sharks.
Top 10 Species
Landbased
- MARION BAY JETTY: Public timber jetty extending over clear water and ribbon weed patches in Marion Bay. Cast size 3.0 or 3.5 squid jigs along dark weed margins during a rising tide for Southern Calamari. Dropping light patternoster rigs baited with peeled prawns beside pylons pulls Silver Trevally and Tommy Ruff.
- BROWNS BEACH SURF WASH: World-famous national park surf beach featuring deep turquoise gutters and heavy Southern Ocean swell. Cast 40g to 60g metal spinners or whole pilchards on ganged hooks into wave troughs for massive Australian Salmon. Exercise caution on the beach wash and monitor incoming swell sets carefully.
- STENHOUSE BAY JETTY: Historic timber jetty sitting beneath high sea cliffs inside Innes National Park. Cast size 3.0 squid jigs over deep kelp patches for Southern Calamari. Casting 28g metal spinners far out into current seams pulls schooling Australian Salmon and Snook.
- PONDALOWIE BAY ROCKS: Rugged granite rock ledges surrounding the bay entrance facing open Southern Ocean water. Cast heavy metal jigs into deep water for Yellowtail Kingfish and Australian Salmon chasing baitfish close to rocks. Sturdy non-slip footwear and extreme caution are mandatory near ocean swell waves.
- ETHEL BEACH SURF GUTTERS: Wild ocean beach backed by towering cliffs near the historic Ethel shipwreck site. Set up heavy surf rod stands and cast patternoster rigs loaded with fresh squid strips beyond the shore break for Sand Flathead and Gummy Sharks. Overcast days provide ideal conditions for beach anglers.
Offshore
- ALTHORPE ISLANDS DROP-OFF: Deep ocean island group sitting in 30 to 60 meters depth off Cape Spencer. Troll large skirted lures or 160mm diving hardbodies at 8km/h around island drop-offs for giant Yellowtail Kingfish and Samson Fish. Anchor up-current of rock ledges and drop heavy rigs for Nannygai and Gummy Sharks.
- PONDALOWIE BAY MARGINS: Sheltered wilderness bay holding clear sand gaps and ribbon weed beds in 3 to 8 meters depth. Drift across clear sand gaps casting double-hook patternoster rigs baited with squid strips for limits of Sand Flathead and King George Whiting. Deploying a sea anchor slows your drift speed.
- WEDGE ISLAND PASSAGE: Deep oceanic channel separating Wedge Island from the mainland in 25 to 50 meters depth. Troll live squid or slow-boat swimbaits around deep reef pinnacles for Yellowtail Kingfish and large Australian Salmon. Always maintain a dedicated helm lookout for sudden swell changes.
- CAPE SPENCER KELP REEFS: Heavy kelp and granite reef system sitting off the headland in 10 to 20 meters depth. Bottom-bounce fresh squid strips or fish fillets on heavy rigs for limits of Sand Flathead and Pinkie Snapper. Heavy 80lb leader is required to handle sharp bottom rocks.
- MARION BAY INSHORE WEED BEDS: Shallow weed flats sitting in 2 to 5 meters of clear water inside the bay. Kayakers and tinnies drift over weed margins casting size 2.5 squid jigs or light whiting rigs for Southern Calamari and Garfish. Clear water days with light winds deliver ideal conditions.

Local Bait Tips
- SOUTHERN CALAMARI: Caught off Marion Bay Jetty or Stenhouse Bay jetty using size 3.0 squid jigs. Slice fresh tubes into thin fluttering strips for Flathead bait or use whole live squid for offshore Yellowtail Kingfish.
- COCKLES (PIPIS): Hand-gathered along sandy intertidal wash zones on ocean surf beaches at low tide by foot-twisting in wet sand. Thread two whole cockles onto long-shank hooks for King George Whiting and Sand Flathead.
- GHOST SHRIMP (PINK NIPPERS): Pumped using a stainless steel yabbie pump on exposed low-tide sandflats inside Marion Bay. Keep alive on damp sea-sponge in a cool shade box as top bait for King George Whiting.
- BLUE MUSSELS: Hand-scraped from sub-surface jetty pylons around Stenhouse Bay below the low-tide mark. Thread soft mussel meat onto fine wire hooks for Silver Trevally and Tommy Ruff.
Boat Ramps
- Marion Bay Boat Ramp:
Marion Bay Boat Ramp is located off Slow Street on the Marion Bay foreshore next to the general store, managed by Yorke Peninsula Council. The coastal facility consists of an unsheltered single-lane concrete launching ramp with no protective breakwater, making launching hazardous during heavy Southern Ocean swell or heavy weed accumulation. Amenities include paved trailer parking, public restrooms, and fish cleaning table.
- Pondalowie Bay Boat Ramp:
Pondalowie Bay Boat Ramp is located off Inneston Road inside Dhilba Guuranda-Innes National Park at Pondalowie Bay. The wilderness site is an unpaved 4WD-only beach launch over firm sand, serving as a primary beach launch point for small craft navigating Investigator Strait on high tide. Amenities include unpaved trailer parking, public restrooms, and parkland camping reserves.
