Adelaide FAQ

When was the former warship HMAS ADELAIDE scuttled as an artificial reef?

The ex HMAS Adelaide was scuttled on April 13th, 2011.


When is the best season to dive the HMAS Adelaide?

March to September, during our Autumn or Winter. Expect calmer water with very little swell due to the Westerly Winds- Water temp is around 17 to 18 degrees. Some years we experience a few weeks with lower than normal water temperatures around 15 to 16 degrees in late June or early July.  Visibility ranges up to 40 metres.

Around October, Spring and Summer the air and water temperatures begin to warm up, during Summer the afternoon north easterly winds occur and this can make diving the east coast a little uncomfortable after lunchtime.  Visibility ranges from 15 to 30 metres.

Following severe storms, the local ocean water is obviously very dirty and the visibility around the wreck becomes very low, around two to four metres.

Several times a year the site is visited by a school of Jewfish with several Grey Nurse sharks dropping in, for a break.

To fully explore the entire ship, you will need to do around 25 dives. The HMAS Adelaide has three top deck levels and four below deck levels. There is a junior Sailors cafe with several corridors leading to other parts of the ship. A galley, Sick Bay, gigantic gearbox, open Bridge as well as the forward and aft decks along with machinery spaces, open covered areas and helicopter hangars.
