Yorke Peninsula Diving Sites
Althorpe Island, South Australia
With depths to 40m there are more than 50 great dive sites around the Island, with lots of different things to look at. There are 20metre + walls, reefs, 3 wrecks, a couple of seal colonies, Lots of crayfish, and abalone (in season). Most dives, you will see seals, there are always big blue grouper, as well as schools of other fish.
Ardrossan BHP Jetty
Ardrossan – BHP Jetty, South Australia
Because of the length of the jetty it is best done by boat launching from Ardrossan boat ramp. Huge schools of fish congregate at the end in a depth of around 15m.
Ardrossan Jetty, South Australia
An easy shallow shore dive to 6m good for beginners.
Edithburgh Jetty, South Australia
One of the best jetty dives in the State and a popular night dive with substantial marine diversity. Lots of nudibranchs and seahorses under the jetty. The pylons are covered with sponges. Usually there are heaps of fish life, cuttlefish, squid, octopus and dumpling squid. Port Jackson and small cat sharks are sometimes seen. 50 metres out from the north side of the jetty, there is also a reef, with lots of life on it too.
And a tip from Steve Simmons about how to judge whether conditions are good for diving at Edithburgh:
If wind is N NE or E even though they maybe light winds vis will usually be poor, N = average to poor NE = poor. E = atrocious.
SE = generally ok S = Good to Great Sw & W = Really good NW = usually OK
Haystack Island, South Australia
There is a reef approximately 500 metres off the shore of the Island, running parallel to it. It is a big wall, running the length of the island (more than a kilometre) with the sand at 22 metres, and the wall going up to about 10 metres in some spots. There are caves everywhere, swim-throughs, chasms and gorges. The wall is so long, you can easily do many dives there all in different spots. There are crayfish in abundance. The sponge and soft coral life has to be seen to be believed, it is so colourful, red, yellow, and orange everywhere. But probably the best thing about this wall, is the abundance of fish.
Point Turton Jetty, South Australian
Whilst the jetty is shallow at 5m, the is a lot of life on the pylons and nudibranchs and blue ring octopus are often found here.
Port Giles Jetty, South Australia
This is a long, working grain loading jetty. We’ve recently received word that diving, fishing and snorkelling have been banned from the jetty itself by the owners regardless of whether there is a ship at the jetty or not. In the past, shore diving access has been possible from the steps at the beginning of the jetty, or as a boat dive launching from Edithburgh boat ramp. There is lots of life under the jetty with the pylons covered in sponges and soft corals. There is a big eel bed, with lots of eels there. It’s quite deep for a jetty, getting up to around 14 metres at the tank at the end of the jetty.
Port Hughes Jetty
Port Hughes Jetty, South Australia
A very underrated jetty. Fish life is prolific, including large numbers of Cowfish. There are nudibranchs galore and this is a macro photographers paradise, with the chance of spotting seahorses amongst the abundant and colourful growth on the pylons or on the Sargassum algae on the periphery. Access is easy, with plentiful parking close to the jetty and toilets with a (cold water) shower. It is a shallow dive (5m), allowing plenty of time to cruise to the end and back.
Port Victoria Jetty
Port Victoria Jetty
A very pretty dive, if a short one. See also Wardang Island for the historic shipwrecks off Port Victoria.
Stenhouse Bay Jetty
Stenhouse Bay Jetty, South Australia
This is a lovely jetty dive in 10m with shore or boat access. Boats can be launched from Marion Bay boat ramp. There is amazing life on the numerous pylons of this old wooden jetty. At the end of the jetty is a Ford Telstar upside down.
Troubridge Point, South Australia
This can be dived either from shore or by boat. Access to the best areas is by boat launched from Edithburg boat ramp. It is a large reef system, that covers a couple of kilometres of shoreline, with huge swim through, bommies, chasms, pinnacles. Depths range to 20m. Fish life is amazing and crayfish plentiful but cannot be taken inside the section of reef inside the reserve.

Songvaar, South Australia
The Songvaar was an 85m iron ship of 2128 tons that sank on 14 April 1912, the same day as the Titanic. The Songvaar was loaded and ready to sail and sat on her anchor as the tide went out and sank herself. Because of the danger to shipping in the area the wreck was subsequently blasted. The offending anchor can still be seen piercing the hull. The fish life on the wreck lying in 9m is amazing.

A very shallow dive to around 4 metres but the home of many leafy seadragons.
