4 Mile Reef is a 18 m reef dive on our beautiful 4 Mile Reef in Busselton. It is only a short boat ride away from the marina and has great coral and schooling fish to offer.

The 2750-ton, 140-meter long HMAS Swan was scuttled in Geographe Bay in December 1997 in 30 meters of clear water to provide a world-class wreck dive site.

Formally a fishing vessel caught illegally fishing Patagonian Tooth Fish in Australian Antarctic waters, the vessel was seized by the Australian Navy, with a decision to sink the vessel as a purpose sunk, shipwreck. There is a mooring line that connects to the bow of the ship doubling as a descent line. Max 18m

3 minute walk from chelydra park car park, beach entry, walk out to about 2.4metres before a drop off to about 4metres, sand bar to left along the wall stays at 1.9metres until dropoff roughly 150m from shore then drops down to4.5m

Located 1km west of Rottnest Island, the Nurses Quarters dive site includes the famous “Shark Cave.“ From the reef, the main cave drops to 26m of water and usually hosts a group of grey nurse sharks. Only trained divers with the appropriate certification should enter the cave.

This dive site is located 850m southwest of Dyer Island. There are caves and swim-throughs all over the site. The maximum depth is 18m. Remember to bring your torch when diving this dive site.

Throughout this dive, you will see caves and bomi walls. There can be currents in some areas so be aware.

Great for crayfish and freediving. Some spots are not very deep, have great color, and some caverns and small areas to swim through. Overall this is a great spot for an open, widespread dive.

Situated about 5km northeast of Rottnest Island, this reef is a mild slope that goes from 23m to 31m. The Opera House is a rock inside the large cave system.

Bad visibility at times due to suspended seagrass, but clear areas are interesting. Sheltered and calm area, great for beginners. Nice variety of fish hanging about the rocks and large shoals of baitfish nearby. If you stay near the wall boat traffic shouldn’t be a problem
