NSW DPI installed Australia’s largest offshore artificial reef complex off the southern Sydney coast during October 2017 to increase fishing opportunities in the region. The reef is accessible from Port Hacking and Port Botany.
Named in honour of the late John Dunphy, a tackle industry pioneer and national fishing industry giant, the reef complex consists of 36 individual concrete modules weighing 25 tonnes each and measuring 4 metres wide and standing 5 metres high. Ten of the modules have vertical steel towers to increase vertical relief to 9 metres. The reef modules have been deployed in a patch-like arrangement, similar to the Shoalhaven Heads and Port Macquarie offshore artificial reef designs.
The JD artificial reef comprises of a total reef volume of around 2900 m3 and is spread over two areas of 100 by 100 metres.
The reef is located in a sandy area situated approximately 2.5 km south-south-east of Jibbon Point in 30 metres of water within 1 km offshore from the Royal National Park.
The reef was funded from the Transport for NSW Port Botany Boating and Fishing Infrastructure Fund and the efforts of the Recreational Fishing Alliance of NSW, ANSA (NSW Branch) and the South Sydney Amateur Fishing Association in securing funding is appreciated.
