Glenelg Tyre Reef is a purpose-built artificial reef sitting at 18 metres, constructed from tyres that have accumulated enough biological growth to attract a solid cross-section of temperate South Australian marine life. Visibility holds around 10 metres, giving you enough range to work the structure methodically. Currents run variable, so check conditions before descending. The reef holds cuttlefish, spider crabs, old wives, bullseyes, and silver drummer, with whiting and strongies working the surrounding sandy bottom. The tyre matrix creates genuine entanglement risk, so buoyancy control matters here. Boat traffic in the area demands a surface marker buoy on ascent.

Current direction can shift with the tide and affect how fish stack up on the structure, so a slack-water dive will generally give you calmer conditions and better marine life activity. Confirm live boat traffic patterns with your charter operator before the dive, as the site sits within a busy coastal corridor.
Access is by boat, typically from the West Beach boat ramp. The reef is located 5kms west of Glenelg.
The main hazard is the potential for loose regulators and gauges to get caught in the tyre straps of the reef structure. The area is also a fishing site, so divers should be aware of boat traffic and anchors.

Advanced training in navigation and buoyancy control is essential for safely exploring this South Australian dive site.
Glenelg Tyre Reef hosts diverse temperate species including whiting, cuttlefish, bullseyes, and silver drummer. The artificial reef structure attracts spider crabs, old wives, and strongies throughout the year. The tyre formations provide shelter and hunting grounds for these cold-water species in South Australian waters.
Water temperatures at Glenelg Tyre Reef range from 13°C in winter to 23°C in summer. A 5mm wetsuit or drysuit is recommended for winter months, whilst a 3mm suit suffices during warmer periods. The temperate conditions reflect typical South Australian coastal temperatures throughout the year.
Glenelg Tyre Reef offers optimal diving conditions from January through August. These eight months provide the most reliable visibility of 10 metres and manageable sea conditions. Winter months may offer clearer water but require thicker thermal protection due to cooler temperatures.
The primary hazards at Glenelg Tyre Reef include entanglement risk from the tyre structures and active boat traffic overhead. Divers must maintain excellent buoyancy control to avoid snagging on the artificial reef materials. Surface marker buoys are essential to alert boat traffic of diver presence at this Adelaide Metro site.
Glenelg Tyre Reef in Adelaide Metro requires advanced diving skills. Expect deeper depths, currents, or challenging conditions that are not suitable for newly certified divers.
