Blacksmiths Beach Artificial Reef (the B. Bar)

In August 2019 the DPI (Dept Primary Industries) sank two single steel pinnacle reef towers of the dimensions 7.8 (W) x 10.9 (D) x 6.4 (H) in metres, each have a central vertical tower to a maximum of 12 metres. We have started diving these towers and watching how the new reef is colonised by marine life.


Purpose built structure sunk off Blacksmiths Beach in 30m of water. It's about a kilometre or so off the coast, so you will need our boat to get there. Every time we visit we see more growth and fish life is getting better every time.

Must be experienced Diver with an Advanced or higher certification to dive this site.

The Arch is a large swim thru in one of two big bommies a short distance off the main Moon Island wall. It is always full of fish. A great site in which we leave the Arch and swim a circuit that includes the In & Out Cave, the Hidden Cave, #3 and the Squeeze Thru. A fun site maximum depth 20 m. 


Moon Island 

is a small island situated just outside the entrance to Swansea Channel only a few minutes by boat from the wharf near Swansea RSL . Between the Island and the headland, Reid's Mistake is a shallow sandy area with a few areas of kelp covered rocks; the best diving is out on the northern, eastern and southern sides of the island. The underwater seascape of Moon Island features walls, sea caves, massive boulders and swim throughs. Fixed growth includes colourful sponge and ascidian, gorgonia, plate corals and areas of kelp. All the usual local fish life abounds: blue wrasse, morays, morwong, pomfreds, wobbegongs, and even eastern blue devilfish. At various times of year salmon, grey nurse sharks,  and kingfish and other pelagics visit. Sea turtles and giant cuttles are often spotted too as well as the occasional weedy seadragon.
