The Harry Atkinson Artificial Reef is 7km east-south-east of St Helena Island, covering 34ha in about 21m of water.

The reef was created in 1975 with 17,000 car tyres.

In 1987, 200 shopping trolleys were added.

In 2008, about 150 cubic metres of quarried rock was added.

The 24m Tiwi Pearl was scuttled on-site in 2010, standing upright. The highest point is 12m up from the sea floor.

Also in 2010, 450 tonnes of concrete pipe was deployed in four locations.

Each cluster was 23 pipes of different sizes, ranging from 2.5m to 6m above the seabed.

In 2014, a 26m, 60-tonne barge was scuttled.

Harry Atkinson Artificial Reef Fish Species

The reef produces a lot of small fish, and a few bigger ones.

The main catch is pink snapper, tricky snapper (“grassies), tuskfish, sweetlip, flathead and jewfish.

Passing mackerel are caught and occasional cobia.

Fish the turn of the tide, be sure to move if you don’t get bites, and try to fish mid-week and at night when boating traffic is lower.
