Jetty pilings, a legendary wreck, and cape-to-cape reefs with world-class wine country in between
Updated Jan 23, 2026 • 16 sources
Overview
Busselton Jetty and the Margaret River Region combine easy, sheltered diving in Geographe Bay with the wilder, swell-exposed capes of South West Western Australia. Under the 1.8 km timber jetty, thousands of pylons create a living artificial reef packed with sponges, schooling fish, and macro life. Nearby, the HMAS Swan wreck delivers one of Australia's most famous dives, with two large sections resting from shallow water down to 32 m. South of Dunsborough, limestone and granite reefs sit inside Ngari Capes Marine Park, where sanctuary zones protect seagrass meadows and seasonal whale migration corridors. Topside, Margaret River is a full-on playground of cellar doors, caves, karri forests, surf culture, and coastal hikes. It is ideal for a long weekend based in Busselton or a week-long loop mixing jetty dives, wreck days, and cape missions with winery lunches.
A shallow, high-biodiversity jetty dive with an underwater observatory and sculpture trail nearby, ideal for training, macro photography, and night dives.
The HMAS Swan is a purpose-sunk artificial reef that delivers big-structure wreck diving without needing to travel to a remote offshore atoll.
Ngari Capes Marine Park protects key habitats (including seagrass meadows) with sanctuary zones while still allowing non-extractive diving and snorkelling.
Margaret River stacks wineries, breweries, caves, and coastal hikes into easy day trips from a single base.
