Little Armstrong Bay is a sheltered shore entry reef dive sitting in easy shallow waters of 6 to 7 metres, making it a comfortable choice for beginners getting comfortable in the ocean. Visibility regularly reaches 15 to 20 metres, so you can take your time exploring the coral and watching the fish life without straining to see. You can expect to encounter King George whiting, bream, buff bream, herring, garfish, cod, salmon, and flathead moving around the reef. Current is mild, so navigation is relaxed. Come prepared for cold water, as a wetsuit is essential year-round here.

The City of York is a historic wreck sitting in easy shallow waters off Western Australia, making it an accessible first wreck dive for beginners. Depths range from 4 to 9 metres, and visibility can reach up to 20 metres on a good day, though 3 metres is possible on less favourable ones. A mild current keeps conditions generally manageable. The wreck and surrounding reef host crayfish, Western Blue Devil, Western Dhufish, Western King Wrasse, Australian Giant Cuttlefish, Harlequin Fish, and various sponges. Watch for sharp coral when exploring the structure, and stay aware of any loose lines or debris that could cause entanglement.

Parakeet Bay is a gentle shore dive sitting in just 1 to 4 metres of water, making it one of the most approachable entries for new divers in Western Australia. The bay combines reef, seagrass beds, and kelp forest in a small area, so there is plenty to explore without covering much ground. Visibility can reach up to 30 metres on good days, though conditions vary. Keep an eye out for Miller's damselfish, sea stars, cuttlefish, and octopuses among the reef structure, and Western Rock Lobster tucked into crevices. Port Jackson sharks rest on the bottom periodically, and the curious Western Blue Groper is a reliable highlight.

Geordie Bay offers one of Rottnest Island's most accessible shore dives, perfect for building your confidence in a sheltered environment. You'll enter from the sandy beach and work your way out over seagrass beds that gradually transition into reef structures, with depths ranging from 1 to 16 metres. The mild current makes navigation straightforward, though visibility changes throughout the day depending on conditions and wind direction. The seagrass meadows attract schools of fish that move in coordinated patterns across the bay, while gloomy octopuses hunt among the rocks if you take time to search the crevices. Stingrays glide over the sandy patches between reef sections, and crayfish tuck themselves into darker spots during daylight hours. Small cave formations along the reef add interest to your dive without requiring overhead environment training. Watch for boat traffic as you surface, particularly during busier periods, and keep an eye out for jellyfish in the shallows. The bay's facilities include toilets and a cafe near the beach, making it easy to spend several hours here. Autumn months from March to May typically offer the most settled conditions for exploring this varied underwater landscape.

Roe Reef is a beginner-friendly boat dive off Western Australia that punches well above its weight for marine life encounters. Depths run from 8 to 18 metres, and visibility frequently reaches 25 metres, making it easy to get your bearings underwater. Currents can run moderate to strong, so stick close to your guide and plan your dive with the flow. Keep an eye on the bottom for wobbegong sharks resting flat against the reef, and check crevices for crayfish and porcupinefish. Buffalo bream and snapper move through in loose groups, while lucky divers occasionally spot dolphins or sea lions passing by. The rare leafy sea dragon rounds out an impressive species list for a single site.

Rottnest Island offers a genuinely varied underwater landscape, with walls, caves, drop-offs, and at least one wreck all accessible by boat. Depths run from 2 to 26 metres, and visibility swings considerably depending on conditions, anywhere from 3 to 30 metres, so timing your dive matters. A moderate current runs through most sites and can strengthen without much warning, so stay aware of your position throughout the dive. Keep an eye on surge near the walls and caves. Reef fish and nudibranchs reward patient divers who slow down and look carefully, while lobsters tend to tuck into crevices and overhangs. Boat traffic is a real consideration on ascent.

Swirl Reef combines a dynamic reef environment with cave sections, giving intermediate divers plenty to work with across depths of 4 to 24 metres. Visibility swings considerably, from 3 metres on rougher days up to 20 metres when conditions align, so timing your visit matters. Current is variable, and surge near the cave openings and sharp coral demand attentive buoyancy. The marine life mix leans characteristically Western Australian: Australian sea lions show up with their usual curiosity, while western blue devils and harlequin fish hold territory around the reef structure. Smooth rays, buffalo bream, western king wrasse, Australian giant cuttlefish, and western rock lobster round out what you can reasonably expect to encounter.

The Basin is a sheltered reef site sitting in easy shallow waters of 1 to 10 metres, making it a comfortable choice for beginner divers and snorkellers.

The reef supports a relaxed mix of marine life including buffalo bream, snapper, wobbegong sharks resting on the bottom, western rock lobsters tucked into crevices, stingrays, and various crustaceans moving through the coral. Current is mild, though be aware of surge near the reef and keep an eye out for boat traffic on the surface.
