Busselton offers a distinctive mix of temperate reef diving, shallow snorkelling sites and two artificial wrecks that anchor the region's appeal. The HMAS Swan draws intermediate divers with its deep, upright hull, while beginner-friendly reefs like The Honeycombs and Busselton Jetty suit newer divers and snorkellers alike. Signature species include the Weedy Seadragon, Spotted Wobbegong, Smooth Ray and Star Octopus. Conditions vary across the region, with sheltered bays offering calm entries and more exposed sites demanding awareness of surge and current.
