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.
