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.

Wells Park Jetty is a sheltered shore entry site sitting in just 1 to 4 metres of water, making it a comfortable first dive or snorkel in Western Australia. The jetty structure itself acts as an artificial reef, giving marine life somewhere to anchor and hide. Visibility is variable, so some days are clearer than others, but the shallow depth means you can take your time. Keep an eye out for seahorses and pipefish tucked into the structure, anglerfish and octopus camouflaged on the bottom, and Australian giant cuttlefish cruising past. Nudibranchs, boxfish, leatherjackets, and smooth rays round out what you might find on a single dive. Watch for boat traffic near the jetty and stay clear of any ropes or lines.

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.

The Saxon Ranger is a deliberately sunk vessel sitting at 18 to 20 metres, making it a solid wreck dive for intermediate divers comfortable navigating in reduced visibility. Expect 1 to 5 metres of viz depending on conditions, so good buoyancy control and careful movement around the structure will serve you well here. The wreck has colonised nicely over time and shelters wobbegong sharks, crayfish, and western blue devils in its recesses. Scorpionfish and stonefish blend into the encrusted surfaces, so watch where you put your hands. Southern eagle rays cruise the sandy areas nearby, and nudibranch hunters will find plenty to photograph on slower passes along the hull.

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.
