Harmer's Haven is a shore dive combining reef and seagrass habitats across a manageable depth range of 0 to 15 metres. Visibility is highly variable, so conditions can shift significantly between visits. Strong current and surge are genuine factors here and demand respect, particularly around the reef where sharp coral adds to the hazard list. Work the reef structure carefully and you'll find Tasmanian Blennies tucked into crevices, Scalyfin and Blue-throated Wrasse patrolling mid-water, and Common Bullseye holding position in the shadows. The seagrass beds reward slower, methodical swimming with crabs, sea stars, molluscs, and sea snails. Port Jackson sharks are also present, making this a worthwhile site for divers comfortable handling variable conditions.
