The Cables is a reef and artificial reef site off Western Australia that rewards intermediate divers with a genuine mix of structure and marine life. Depths run from 8 to 28 metres in the deeper sections, and visibility holds at a solid 10 to 15 metres. Mild currents keep conditions manageable without making it a drift dive. The artificial elements attract reef fish, blue grouper, and the striking Western Blue Devils, while slower divers will find nudibranchs and well-camouflaged scorpionfish tucked into the structure. The entanglement hazard is the primary concern here, so buoyancy control and situational awareness around any cables or lines are essential.

The Fingers is a wall and drop-off site that earns its advanced rating through a combination of surge, depth, and moderate to strong current. The reef structure drops to 30 metres, with the shallower sections sitting around 9 metres where surge can be felt along the wall. Visibility runs 10 to 20 metres, giving you solid sightlines into the blue where pelagic fish and wahoo patrol the deeper water. Breaksea cod and WA blue grouper hold close to the structure, while pink snapper and queen snapper work the mid-water column. Plan your bottom time carefully at depth.

The Cheynes III is a decommissioned vessel sitting in depths of 10 to 30 metres off Western Australia, now thoroughly colonised by sponges and corals that have transformed its hull into a functioning artificial reef. Visibility can reach 30 metres in good conditions, though currents are variable so it pays to check before descending. Blue groper patrol the structure with little concern for divers, and sea dragons appear around the shallower sections if you look carefully. Seals occasionally visit and make for an unpredictable but rewarding encounter. Standard wreck protocols apply here: treat entanglement risks seriously and treat any penetration as an overhead environment requiring proper preparation.

Herold Reef is a boat-access reef dive off Western Australia, sitting at depths of 4 to 16 metres with visibility typically running 10 to 15 metres. The mild current keeps conditions manageable for intermediate divers, though surge and surf at the surface require a confident entry and exit. WA Dhufish and Queen Snapper are the standout residents here, both species being particularly prized sightings in these waters. Western Blue Groper add size and character to the reef, moving unhurriedly between structures, while a solid mix of reef fish fills out the water column. The site dives well year-round.

Willy's Lump is a reef dive in Western Australia that suits beginners thanks to its mild current and accessible depths ranging from 2 to 18 metres. Visibility here is variable, so conditions can shift, but that unpredictability is part of what keeps the site interesting. Keep your eyes on the reef structure and you stand a good chance of spotting wobbegong resting on the bottom, Western blue devil fish, and cuttlefish moving through the shallower sections. Samson fish, grouper, and a range of demersal and nearshore species round out the resident life. Watch where you place your hands and fins, as sharp coral, sea urchins, and jellyfish are present.

Limestone Head offers a varied underwater landscape for beginner divers, combining reef, wall, and cave features across a shallow depth range of 2 to 13 metres. The mild current keeps conditions comfortable, and visibility regularly reaches 5 to 15 metres, giving you a clear view of the site. The resident marine life is the real draw here. Samson Fish and Blue Morwong are commonly encountered around the reef structure, while Western Blue Grouper are known to be approachable and curious. Silver Drummer tend to move in groups, making them easy to spot. The site dives year-round and suits those still building confidence underwater.

Gull Rock Beach offers a straightforward shore entry into shallow water, making it a solid choice for new divers building confidence. The site combines a reef and a wreck within depths of 5 to 8 metres, so you spend more time exploring and less time managing buoyancy. Visibility runs 5 to 10 metres and currents are mild, keeping conditions manageable year-round. Keep an eye out for Australian Giant Cuttlefish hovering near the reef, along with Western Blue Groper, Old Wife, Leatherjacket, and various Wrasse moving through the structure. Watch your hands around the reef, as some coral edges are sharp, and be aware of surf on entry and exit.

HMAS Perth II is a decommissioned warship sitting on the seabed off Western Australia, resting at depths from 5 to 38 metres. The wreck is substantial enough to reward multiple dives, with visibility ranging from 10 to 25 metres giving you good sightlines along the hull. Resident marine life includes blue groper, blue devils, pink snapper, queen snapper, samson fish and break sea cod, while wobbegong sharks and other sharks are regular visitors. Nudibranch and tasmanian blenny add smaller-scale interest for those who take their time. Current is generally mild, but the deeper sections push into decompression diving territory, so solid buoyancy control and dive planning are essential before heading down.
