The Hot Tub earns its name from the thermocline you'll encounter as you descend, where distinct temperature layers create a noticeable shift in the water column. Depths reach 25 metres in the deeper sections, though conditions vary considerably, with current and visibility both running unpredictable on any given day. Seagrass beds draw dugong and loggerhead and green sea turtles, making patient, slow dives more rewarding than rushing the site. Wobbegong and shovel nosed rays favour the bottom, while sea snakes are a regular presence. Watch where you place your hands near the reef as stonefish inhabit the area. Tiger sharks have been recorded here.

Little Lagoon is a sheltered shore entry site in Western Australia, best suited to beginners and snorkellers exploring calm, shallow water between 1 and 4 metres deep. The bottom is a mix of reef and seagrass beds where sea bream, whiting, and flathead move through regularly, and stingrays rest or cruise along the sandy patches. Keep an eye out for crustaceans tucked into the reef, and if you look closely at the substrate, you may spot microbialites, ancient living rock structures that are genuinely worth pausing over. Visibility varies, so conditions can change between visits. Watch where you step and avoid putting your hands down, as stonefish are present.

Denham Jetty offers one of the most accessible dives in Shark Bay, where you can explore a fascinating mix of underwater habitats just steps from shore. You'll enter from the beach near the jetty and wade into easy shallow waters ranging from 4 to 6 metres deep, perfect for building your confidence if you're new to diving. The site combines three distinct environments in one dive. Patches of reef provide structure where you'll find pink snapper, mulloway, and schools of tailor hunting in the shallows. Seagrass meadows attract rays gliding across the sand, while the mucky areas hide seahorses and pipefish if you look closely. Squid often drift past in the mild current, and whiting dart through the grass beds. Visibility ranges from 10 to 30 metres depending on conditions, giving you clear views across the varied terrain. The mild current makes navigation straightforward, though you'll need to watch for boat traffic as this is an active jetty. The combination of easy conditions, diverse marine life, and shore access makes this an ideal site for practising your skills or trying underwater photography without venturing far from land. Parking is available right at the jetty, so you won't have far to carry your gear.

Eagle Bluff offers a shallow, calm water experience in Western Australia, making it a comfortable introduction to snorkelling. The site sits between 1 and 5 metres deep, with seagrass beds covering much of the bottom. These seagrass meadows attract dugongs and green sea turtles, so keep your eyes scanning the sandy areas between patches. Rays, shovelnose rays, and nurse sharks are also regularly seen resting on the substrate. Visibility here is variable, so conditions can change, but the mild current keeps things manageable for beginners. Reef sharks are present, though encounters are generally calm. Sea urchins on the reef are worth watching underfoot.

Gregories sits within Francois Peron National Park and offers a gentle shore entry into shallow, calm waters, making it a good choice for beginner snorkellers and divers. Visibility varies depending on conditions, so a calm day will reward you with clearer water. The site attracts a varied mix of marine life including bream, whiting, kingfish, and the occasional shark. Turtles, dolphins, dugongs, and manta rays are also spotted here, though sightings depend on timing and luck. Keep your eyes open and move slowly. Be aware of stonefish resting on the bottom and avoid touching or chasing any wildlife.

Bottle Bay is a sheltered shore entry reef site that suits beginners well, with depths ranging from 1 to 12 metres and a mild current that keeps things manageable. Visibility can vary considerably, so conditions on the day will shape your experience. The reef attracts a good mix of marine life, including schooling fish, pipefish, shovelnose rays, and southern stingrays moving through the seagrass. Loggerhead and green sea turtles turn up here, and dugong have been spotted in the area too. Keep an eye out for nurse sharks resting near the bottom. Before entering, scan the shallows carefully for stonefish, and check surf and rip conditions at the entry point.

Broadhurst Corals is a boat-access reef site off Western Australia that rewards intermediate divers with a solid mix of macro and pelagic life across depths of 0 to 20 metres. Visibility ranges from 5 to 20 metres depending on conditions, with the site showing its best face in April and October. Plate corals form the structural backbone of the reef, while wobbegong sharks and Australian giant cuttlefish provide slow-moving subjects worth lingering over. Loggerhead turtles, reef sharks, trevally, and emperor fish round out the larger residents. A moderate current runs through the site, so buoyancy control and awareness of your position matter here. Sea snakes are present and best observed from a respectful distance.
