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.

Bicton Baths is a sheltered shore entry on the Swan River, making it one of the most accessible spots in the Perth area for new divers and snorkellers. The sandy, silty bottom sits between 2 and 6 metres deep, and while visibility can vary from murky to around 8 metres, the shallow depth means you stay comfortable and in control. This is classic muck diving territory, so slow down and look carefully. Seahorses turn up here, along with flounder buried in the sand, crabs, prawns, and schools of bream and yellow tailed grunters. Watch for blowfish drifting through the shallows. Current is mild, though boat traffic is a real consideration, so tow a surface marker buoy.

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.

Elizabeth Reef is a boat-access site off Western Australia that rewards beginner divers with a mix of reef exploration and cave features across depths of 0 to 20 metres. Visibility varies, so conditions can change between visits, but the marine life here is genuinely varied. Look out for Australian sea lions, which may approach with curiosity, along with dhufish, wrasse, and the striking western blue devil. Port Jackson sharks and Australian giant cuttlefish are regulars, and the reef structure supports healthy sponge growth alongside nudibranchs and western rock lobster. Current is generally mild, though stronger surges can occur, so check conditions before entering.

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 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.

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.

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.
