General Marine Park Information

The first Marine Park established under the current regime of legislation, at 3119km2 Encounter Marine Park runs from Christies Beach on the mainland across to Point Marsden on Kangaroo Island, around to Cape Willoughby then back past Goolwa on the Sir Richard Peninsula. This Marine Park also covers the original mouth of the Murray River which extended an incredible 87 kms out to sea further than its current position.

The typical form of coastline in this marine park is high-energy sandy beaches interspersed amongst rocky headlands and backed by low-medium height cliffs. Significant shallow and deepwater reef structures are present all along the coastal boundaries, with seagrass meadows also found on some of the sandier bottomed sections. The coastline of Kangaroo Island included in this marine park also offer many sheltered bays and estuaries.

Fishing Information

Along the western coast of the mainland in this marine park area, anglers will find snapper, sweep, shark and trevally along the outer reeef systems and squid, whiting and tommy ruffs in the shallower, calmer waters. The eastern section (near Goolwa and further south into the Coorong), fishos with a 4WD can access the beach for salmon, mulloway and shark.

The coast of Kangaroo Island offers alot of fishing in this area, with some wild and rugged environments near Cape Willoughby, getting progressively more sheltered and calmer as head north/northwest along the coast. Anglers will find plenty of King George whiting, bream, flathead, mullet, garfish and tommy ruff, plus squid, snook and trevally as you get closer to the Point Marsden area.
