Meet the site

The Noarlunga Tyre Reef is the original structure of the Noarlunga artificial reef, a field of tyre pyramids spread over a wide area of sand in 18-20 m off Port Noarlunga. It was built as a fish breeding reef and later became the site for the HA Lumb (1994) and the MV Seawolf (2002), which now sit alongside and partly within it. The pyramids provide shelter on a featureless silty seabed, and the Federation, Dive Shack and Marine Life Network all describe abundant fish. Boarfish, cowfish, cuttlefish, octopus, blue devils, morwong, bullseyes, perch and wobbegongs are listed, and small fish crowd around the modules. The tyres carry sponges and small invertebrates. No particular hazards are listed, and local guides call it a pleasant dive. The Marine Life Network warns that the pyramids are visually similar and it is easy to become disoriented, so compass navigation is important, especially in low visibility. Most divers use the reef as the third element of a dive on the two wrecks, or as a relaxed second dive at a similar depth. The tyre reef suits Open Water divers comfortable at 18-20 m and those practising navigation, and it offers a good chance of wobbegongs and cephalopods. It is also an interesting example of the tyre-reef era of artificial reef building in South Australia, which began off Glenelg in the 1970s. The site's proximity to O'Sullivan Beach makes it an easy half-day outing. A torch helps to look into the dark centres of the pyramids, where octopus and small crayfish often hide.

Research this site before booking

Noarlunga Tyre Reef is recorded as Artificial Reef in Adelaide Metro. The listed access is boat (day trip). Confirm the actual meeting point, route and permission to visit; a map pin does not establish any of these.

Topics flagged by the stored research

These are questions prompted by the existing notes, not a verified or complete hazard assessment.

Current and timing
Ask how the operator assesses the current window for the actual route. Historical tide notes are not a departure instruction.
Other water users
Ask about vessel activity, exclusion areas and the agreed surface arrangements.

Historical access notes exist for this record, but have not been independently verified for current use. Request current directions from the operator or site manager rather than following an old entry description.
