North Leighton and South Cottesloe offer a gentle introduction to reef diving along Perth's metropolitan coastline. The site combines shallow reef and seagrass habitats, with depths staying between 1 and 10 metres, making it well-suited to new divers building confidence. Visibility runs from 10 to 30 metres, so you can see clearly without having to venture deep. Current is variable, so check conditions before you enter. Various reef species inhabit the rocky sections and surrounding seagrass. Watch out for breaking waves on entry, boat traffic in the area, jellyfish, rip currents, and sharp coral once you are on the reef.

The Cables is a shore dive combining natural reef and artificial structures with seagrass beds, giving you a decent range of habitats across a single entry. Depths run from the shallows down to 28 metres in the deeper sections, and visibility can reach 30 metres on a good day, though it varies considerably. The real draw here is the chance to find both leafy and weedy seadragons, often tucked among the seagrass. Western blue devils, blue grouper, nudibranchs, and scorpionfish round out the resident life. Mild current keeps conditions manageable, but watch for surf on entry, surge at depth, and boat traffic throughout the dive.

Cottesloe is a welcoming shore dive offering easy shallow waters between 1 and 7 metres, making it a great choice for new divers building confidence on a real reef. Visibility typically runs from 5 to 15 metres, so you can actually see what you are looking for. The reef is home to some genuinely special creatures: weedy and leafy seadragons are the standout finds, both masters of camouflage that reward a slow, patient approach. Octopus, stingrays, and Port Jackson sharks are also regular sights, along with schooling herring, tailor, whiting, and the occasional blowfish. Current is generally mild, though watch for rips near the groyne, surf, jellyfish, and boat traffic.

North Cottesloe Reef sits just off the beach in shallow water, making it an ideal first reef experience for new snorkellers and beginner divers. The reef runs at 1 to 4 metres depth, so you can take your time exploring without worrying about depth. Visibility ranges from 3 to 15 metres depending on conditions, and on a clear day the reef structure is easy to follow from the surface. You'll find various reef species going about their business among the corals. Watch for surge near the reef, as it can push you toward sharp coral, and time your entry carefully to avoid breaking waves at the shore.

Rocky Bay is a shallow shore dive that suits beginners well, with easy entry and depths that stay within 9 metres throughout. The site combines a reef with a small cave, giving you two distinct environments to explore in one outing. Visibility here is variable, so conditions can change day to day, but mild currents generally keep things manageable. Take your time on the reef and you will find seahorses, nudibranchs, tube worms, crabs, and starfish tucked into the structure. Be aware of boat traffic in the area, watch for jellyfish, and avoid loose lines or ropes that could cause entanglement.

The Coombe is an estuarine shore dive in Western Australia that rewards patient, observant divers willing to work with challenging conditions. Visibility runs from 1 to 7 metres depending on tidal movement and season, so this is not a site for those expecting crystal water. Depths reach 22 metres in the deeper sections, though much of the interesting life sits shallower. Moderate to strong currents require solid buoyancy control and timing your entry around the slack. The payoff is genuinely unusual marine life: freshwater jellyfish, river prawns, and decorator crabs share the habitat with seahorses, octopus, anemones, and leatherjackets. Boat traffic and entanglement hazards mean a surface marker buoy is essential.

Scout Hall is a calm, shallow shore dive that suits beginners well, with depths staying between 0 and 10 metres throughout. Visibility can shift from 1 to 6 metres depending on conditions, so you may need to slow down and search carefully, which actually rewards patient divers. This is a good spot for finding creatures that hide rather than swim, including seahorses, nudibranchs, and gurnard perch tucked into the bottom. Boxfish, leatherjackets, and pufferfish also move through the area, along with the well-camouflaged goblinfish. Current is generally mild, making this manageable for newer divers. Watch for boat traffic near the entry and be mindful of any lines or debris that could cause entanglement.

The Swan River offers an unusual urban diving experience where you can explore beneath Perth's waterways without leaving the city. This sheltered estuary system suits divers just starting out, with shore entries and depths ranging from shallow water to 18 metres. The moderate current adds a gentle drift element to your dive, though you'll want to time your entry with the tides. Visibility varies from near zero to 10 metres depending on conditions and location along the river. The murky water creates classic muck diving territory where careful observation reveals surprising marine life. You'll find seahorses clinging to pylons and debris, prawns scuttling across the bottom, and crabs tucked into crevices. The fish population includes bream, yellow tailed grunters, flounder and blowfish, with occasional sightings of bull rays gliding through the gloom. Keep your eyes open for squid and the distinctive boxfish. Several wrecks rest on the riverbed, providing structure for marine life and navigation points in the limited visibility. The shore entry makes access straightforward, with parking available at entry points. Watch for boat traffic throughout your dive and be aware of potential entanglement hazards in the murky conditions. The Swan River proves that interesting diving exists in unexpected urban locations.
