Grain Terminal is an industrial dive site that rewards experienced divers willing to work for their exploration. Strong currents run through the area consistently, demanding solid buoyancy control and current-reading skills before you drop in. Depths run from 10 to 20 metres, but visibility of 2 to 5 metres means you'll be navigating largely by feel and compass rather than sightlines. The underwater environment is defined by industrial debris, which creates an unconventional and genuinely interesting structural dive. Boat entry is required, and conditions here are serious enough that this is not a site to underestimate.

Apex Club offers an accessible shore dive that's perfect if you're building confidence in Western Australian waters. The reef sits between 8 and 18 metres, giving you plenty of time to explore at a comfortable depth. Visibility varies from 1 to 6 metres, which might feel limiting at first, but it actually makes this site brilliant for practising close-up observation skills. You'll need to move slowly and look carefully, which is exactly how you spot the smaller residents here. The mild current makes navigation straightforward, letting you focus on the marine life rather than fighting the water. Keep your eyes on the reef structure for seahorses clinging to soft corals and sponges, while wrasse and blennies dart between crevices. Old wives and stripeys patrol the mid-water, and you might find boxfish hovering near the bottom. Eels tuck themselves into holes, and sea stars dot the reef surface. The limited visibility and reef structure mean you'll want to stay aware of your surroundings to avoid entanglement. Enter from shore where you'll find parking and toilets, making this a practical choice for a relaxed day of diving. The site works well from September through May, giving you most of the year to visit.

Bulk Jetty is an artificial reef built around jetty pylons, giving marine life plenty of structure to gather around in depths of 3 to 15 metres. The mild current and accessible shore entry make it a comfortable choice for newer divers. Visibility ranges from 2 to 10 metres, so conditions vary, but on a good day you can spot Australian Giant Cuttlefish, octopus, fiddler rays, and smooth rays resting on the sandy bottom. Pipefish and seahorses tend to hide close to the structure, so take your time and look carefully. Watch for boat traffic, entanglement hazards around the pylons, and be prepared for surf on the entry.

The D9 Wreck offers an ideal introduction to wreck diving, resting upright at 10 to 14 metres on the seabed. This accessible site lets you explore a genuine shipwreck without venturing into challenging depths or complex interior spaces. You will reach the wreck by boat, where visibility between 1 and 10 metres means you will sometimes need to move closer to appreciate the details. The structure attracts a surprising variety of marine life for such a compact site. Watch for wobbegongs lying motionless on the deck, whilst cuttlefish often hover nearby. Moray eels peer from crevices in the wreckage, and if you look carefully, you might spot scorpionfish or lionfish using the structure as an ambush point. The wreck also hosts smaller residents like boxfish, toadfish, and colourful angelfish moving through the water column. Nudibranchs decorate the encrusted surfaces, and schools of bullseyes often shelter in the shadows. Be aware that currents vary at this site, so listen to your dive guide's briefing. The wreck presents potential entanglement hazards from fishing line or loose cables, so maintain good buoyancy and keep your equipment close to your body. Visibility can drop unexpectedly, making it important to stay oriented and aware of your surroundings. The overhead environment means you should avoid swimming under collapsed sections without proper training.

Point Peron is a gentle shore entry reef dive sitting in easy shallow waters of 3 to 7 metres, making it a great choice if you are new to diving or snorkelling. Visibility ranges from 5 to 15 metres, so you will generally get a clear view of the reef below. The site is known for weedy seadragons, which take some patience to spot among the sponges and sea grass. Rays, sea stars, nudibranchs, and crayfish are regular sights, and seals and dolphins occasionally pass through. There is no current to manage, which lets you take your time and look carefully. Watch where you put your hands and fins, as the reef has sharp coral and sea urchins, and stay aware of boat traffic near the entry and exit points.

Point Peron is a shore entry reef and cave dive sitting in easy shallow waters of 1 to 10 metres, making it a comfortable choice for beginners. Visibility ranges from 2 to 20 metres depending on conditions, and the current stays mild. The reef shelters some genuinely exciting marine life, including weedy and leafy seadragons, Australian giant cuttlefish, western blue devils, and Port Jackson sharks resting on the bottom. Nudibranchs and octopus turn up in the nooks if you look carefully. Be aware of boat traffic, surge near the cave, and sharp coral when entering and moving around the site.

Seal Island's main draw is simple: Australian sea lions. These curious, playful animals regularly interact with snorkellers and divers in the shallow reef and seagrass areas that surround the island. Depths run from 3 to 8 metres, making this very manageable for beginners. Visibility is variable, so some days will be clearer than others, and currents can shift, so keep an eye on conditions before you get in. Beyond the sea lions, you can expect reef fish, stingrays, and the occasional dolphin passing through. Boat traffic is the main hazard here, so stay close to your vessel and use a surface marker when ascending.

Penguin Island offers snorkelling and diving in shallow, calm waters with depths of 2 to 5 metres, making it a relaxed entry point for beginners. Visibility typically runs 5 to 10 metres. The site combines reef and seagrass habitats, where you can spot sea stars, sea urchins, blue manna crabs, and baitfish moving through the shallows. The real draw is the wildlife: little penguins occasionally venture into the water nearby, Australian sea lions may cruise past, and bottlenose dolphins are known to pass through. Mild currents keep conditions manageable, though you should stay aware of boat traffic and any rip currents forming near the shore.
