New Offshore Artificial Reefs Installed At Harvey Bay, Queensland By Subcon Technologies.


The creation of two artificial reefs in the Great Sandy Marine Park means the time has come for families to enjoy a new exciting place to fish, snorkel and dive. Perth based market leader, Subcon Technologies Pty Ltd has successfully completed the installation on the 1st June 2015. The artificial reefs comprise 30 ReefTempleTM modules each 5m high and weighing 23Te.

The 80 hectare Simpson Reef has been installed in 10 metres water depth near the Outer Banks and the Hardie Reef is in 16 metres north-east of Little Woody Island. The new artificial reefs will enhance recreational fishing as well as diving in the great sand straight behind Fraser Island.

The Hervey Bay reefs are constructed from the same proven ReefTempleTM design which was deployed at Shoalhaven in New South Wales earlier this year. Subcon’s ReefTempleTM, is an Australian innovation that interacts with ocean currents to create upwelling and a rich supply of food.

The Subcon ReefTempleTM are a low maintenance, purpose-built, fibre reinforced, concrete module which have been tested in conjunction with the University of Western Australia.

Minister for National Parks and the Great Barrier Reef Dr Steven Miles said the two new artificial reefs will create new habitat for marine life and recreational fishing and diving opportunities.

The Simpson and hardy reefs will provide support for coral communities to establish and complex habitat for sustainable communities of marine life to establish. We expect divers to see interesting creatures around the structures within weeks of completion and fishing should have improved substantially within 18 months.

“It won’t be long before anglers can drop their lines”, Dr Miles said. “The reefs have multiple openings, some large enough to allow diver access and great swim throughs. These openings will allow maximum light penetration while offering great protection for various species of fish.”

The reefs are named after early lighthouse keepers – Woody Island’s first head lighthouse keeper John Simpson (1867 to 1870) and Peter Hardie (1870 to 1897).

Subcon Technologies Managing Director, Matthew Allen said, “Subcon is the leading Australian design and construction company of multi-use marine landscapes and offshore artificial reefs. We use our fabrication and installation experience from delivering projects to the offshore industries to ensure our operations are conducted in accordance with industry best practices for both safety and quality. Our professional team delivered both reefs without incident, ahead of schedule and in the process provided our community with a significant public amenity for fishing, diving and scientific research”.
