Steep Point and the southern end of Dirk Hartog Island sit at the westernmost tip of mainland Australia, where open ocean swells meet shallow reef and seagrass habitat. Depths run from the shallows down to 12 metres, but strong currents and surge demand respect and solid buoyancy control. Visibility varies considerably depending on swell and tide, so conditions can shift quickly. The marine life here is the real draw: turtles, rays, manta rays, dolphins, dugongs, sharks, tuna, and sea snakes all move through this area, with hard and soft corals adding structure to the reef. Plan dives carefully around tidal movement.

Slack water around the tide change gives you the best window to dive here, as the current can otherwise make the site unmanageable. April through October brings more settled conditions, but always check the swell forecast before committing to an entry.
The site can be accessed via a high-clearance 4WD vehicle or by boat. The drive from Denham takes 3-4 hours over 140km of unsealed road, with the final 30km being soft sand requiring low tyre pressures. Alternatively, it is a 50km boat journey from Denham.
The remote location, 4WD track access, and beach entry make it unsuitable for individuals with mobility impairments.
The area is known for strong, tidally influenced currents. Sharks are frequently sighted. The coastline can experience large surf and swells, especially away from sheltered bays.
