HMAS Adelaide underwater tour

The ex HMAS Adelaide is the largest and most accessible former naval dive wreck scuttled as an "artificial dive reef" in the Southern Hemisphere.
At 138.1 metres in length and over 15 metres wide- Four lower levels and three upper decks, this equates to a whole lot of ship to explore.

Making the ex HMAS Adelaide, a very diverse and complex dive site. Even so, it is not too difficult to navigate if you take note of some of the distinctive features in particular, the helo hangars, Operations room, Flinders street, missile launcher, torpedo magazine and bridge, all useful areas to remember as landmarks for orientation to the vessel.

Scuba divers wishing to penetrate the wreck should be suitably qualified, prepared and carry all the necessary equipment including a light source to further explore the dimmer areas. Scuba divers planning to penetrate the wreck, should make at the minimum- one orientation dive outside the vessel, or follow an experienced Diver who some knowledge of the areas of interest and location of safe exits.

Remember at all times, this site has been designed with diver safety as paramount in all aspects.

Bob Diaz, a member of the two committees to ensure the Adelaide was made "Diver friendly" carefully noted and offered advice when asked and inspected the ship, many times over the deconstruction phase- The access holes cut in the hull easily allow two divers to swim side by side to exit the inner parts of the vessel. Whilst vertical accesses were cut in several areas of each deck to allow easy vertical access within the ship to decks above and below without the need to exit the ship.

Pro-Dive has exclusive use of the main mast, mid-ship mooring. This is the best possible position to start your dive, as it makes for a very easy and relaxed dive plus gives you great orientation to the safety stop area on the mast.
Making your descent down our mooring line onto the crossover line at five metres, you follow this line across to the mast at fourteen metres and then take a leisurely swim to the bow or stern. This allows for a relaxed dive that covers the whole wreck. No frantic rush swimming from one end to the other.


Environmental studies commissioned by the EPA confirm that the bio-diversity of the marine life that has already made the HMAS Adelaide home will only increase in size and number as the Adelaide is slowly taken over its intended marine inhabitants. Plus the numbers of animals making the Adelaide their home will only continue to increase as the years go by and the marine life becomes further accustomed to the area.

Book a dive and experience this awesome divesite for yourself.

Don't forget to come back every few months to check out the differences as a living artificial reef, comes to life.
