Chinaman's Hat Island

Can Be done as a boat or shore dive. Boats can be launched at Marion Bay boat ramp. The best diving is at the back of the island. If done as a shore dive, there is a walk along the beach of around 100m and an equally distant reach the semi exposed reef which you have to get up and walk over. Despite the effort, this dive is worth it and is awesome. There are numerous swim throughs, chimneys, caves, ledges and crevices. There is a lot of fish life and the occaisional crayfish. Depth reaches 15m.

Edithburg Jetty

One of the best jetty dives in the Australia 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.

Haystack Island

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.

Port Giles Jetty

This is a long jetty with the only shore diving access at the steps at the beginning of the jetty. It can also be done as a boat dive launching from Edithburg boat ramp. Being a working grain loading jetty access is not permitted when a ship is in. 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

A very underrated jetty. Fish life is prolific. There are nudibranchs galore and this is a macro photographers paradise. Don't let the shallow 5m depth fool you, this is a great dive.

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.

The Zanoni cnnot be dived without a permit issued by Heritage SA. A boat mooring buoy has been installed at the site for the safety of divers and so the wreck will not suffer anchor damage. It is illegal to damage or interfere with the wreck and penalties are severe, and may involve substantial fines, imprisonment and/or confiscation of equipment. The wreck is a marine reserve, so no fishing or taking anything from it.

Built in 1865, and sunk in 1867. Approximately 15 nautical miles from Ardrossan. She was a 3 masted composite ship, 42 metres long. A remarkably intact wreck, for her age. She lies on her side, and a bit of the superstructure is still standing.
