The Fremantle North Mole wall drops to around 10 metres along a structure that reliably concentrates marine life. Visibility runs between 5 and 10 metres, and the mild current keeps conditions manageable for intermediate divers comfortable with shore entries. Work your way along the wall and keep an eye on recesses and ledges where Port Jackson sharks and crayfish tuck themselves away. Western blue devils patrol the structure, and you have a reasonable chance of spotting lionfish, octopuses, and the occasional squid. Surge and boat traffic from the busy port are the main hazards, so stay aware of your surroundings throughout the dive.

Dive on a calm morning before port activity picks up to reduce boat traffic and get the best visibility. The entanglement risk is real here, so tuck away any loose gear and bring a cutting tool.
Park at the end of North Mole Drive near the disabled fishing platform. The entry point is via a break in the rock wall. Entry and exit are challenging, requiring a climb down the rocks. A rope is highly recommended. From the entry point, swim on a bearing of approximately 355 degrees for about 180 metres to reach the barge wreck.
The entry and exit over the rock wall is considered difficult and potentially hazardous; a rope is strongly advised. Divers must be cautious of boat traffic in the nearby channel and potential entanglement from discarded fishing lines. Car break-ins have been reported in the area.
