The underwater sculpture park is the newest attraction at Busselton Jetty. Installed in 2023, it places 13 artworks by Western Australian artists on the seabed at about 8 m, roughly 1.7-1.8 km out along the jetty, near the Underwater Observatory. According to Busselton Jetty, the sculptures serve both as art and as artificial reef, creating hard habitat on the sandy floor of Geographe Bay and extending what is already described as Australia's largest artificial reef. Busselton Jetty's own sculpture pages include a replica of the SS Pericles, the liner wrecked off Cape Leeuwin in 1910.

Because the sculptures sit in clear, shallow water, snorkellers can see many of them from the surface, and on good days about seven are visible from the jetty deck. For scuba divers, the park adds a navigation element to the classic jetty dive: using the map to find each piece, then watching how quickly sponges, algae and fish have colonised them. Over time they will become increasingly encrusted, like the jetty piles.

The park suits everyone from children snorkelling with a parent to divers wanting a relaxed, photogenic dive. It is part of the jetty's sanctuary zone, so no fishing or collecting is permitted. Visitors need the same $5 pass and waiver as for any jetty swim, and entry is from the Universal Access Platform ladders. It is best combined with a dive among the piles and a visit to the Observatory for a dry view of the same reef. Allow time to read the interpretive panels on the jetty deck too.

Buy the $5 dive and snorkel pass and complete the waiver at the Busselton Jetty Interpretive Centre on the foreshore, then walk the jetty (20-30 minutes; gear not allowed on the train - hire a trolley). Enter via one of the three ladders on the Universal Access Platform on the jetty's west side just before the Observatory gates. A $15 waterproof map shows the sculpture layout.

Swan Dive runs daily guided tours by boat.

Sheltered from south-westerly swell but chopped up and stirred by strong northerly and north-westerly winds. On clear days about seven of the thirteen sculptures are visible from the jetty deck - a good check on visibility before gearing up. General pattern in Geographe Bay: sheltered from south-westerly swell by Cape Naturaliste; summer mornings are calm before the afternoon sea breeze, while winter north-westerly fronts roll swell and chop into the bay and reduce visibility for several days.

Enter at the platform ladders, use the waterproof map to navigate from sculpture to sculpture across the sand at 8 m, then finish among the jetty piles before returning to the ladders. Agree a turn pressure before descending (half gas, or a third where current is likely), carry a DSMB, and make a 3-minute safety stop at 5 m.
