General Marine Park Information

The Lower Yorke Peninsula Marine Park is 848km2 in size, centered around Edithburg on the heel of Yorke Peninsula. It extends out into Investigator Strait from Point Davenport in the south, up past Troubridge Shoals to Tapley Shoal, before returning to the coast just south of Stansbury.

This marine park is one of the few that contain attributes from nearly all the other SA marine parks. The coastline in the south is wild and rugged, with sandy beaches, rocky headlands/cliffs and extensive intertidal and submerged reef systems. Conversely, there are also sheltered bays, sand banks, tidal flats and saltmarshes around the two estuarine systems of Point Davenport and Coobowie Inlet.

Fishing Information

The reef systems and rocky bottomed ground make this area an excellent snapper and whiting area if you have a boat and can get off the shore. You can also get decent sized leatherjackets, snook and sweep, and the ubiquitous squid is present of course. In shallow areas or from the jetties/shore, anglers will return home with garfish, tommy ruff and the odd whiting or flathead. Small snapper can also be caught from the jetties over the summer months.
