THERE are currently 29 great whites and 88 bull sharks swimming off the North Coast with satellite trackers lodged under their skin.

The wide-roaming predators are about to get some new friends from down south.

Primary Industries Minister Niall Blair has announced the South Coast will soon receive five listening stations capable of monitoring the sharks' movements, replicating the program operating in the state's top end.

Listening stations will be installed at Kiama, Sussex Inlet, Mollymook, Batemans Bay and Merimbula on the South Coast, with a further five to be installed at Crescent Head, Old Bar, Hawks Nest, Redhead and Bondi.

"When it comes to preventing shark attacks we need to give beachgoers better information, and the fact that listening stations provide real time information of shark movements means people can make informed decisions before getting into the water," Mr Blair said.

"Listening stations will now be located up and down the state's coastline and are just one of the emerging technologies we are using to better detect and deter sharks on the NSW coast."

The stations send out an alert via the @NSWSharkSmart Twitter profile and the NSW Government's Shark Smart app whenever a tagged shark swims within 500m of them.

All listening stations will be in the water by summer, their exact locations subject to coastal engineering and in consultation with local surf life saving clubs.

There are already 10 active stations between Tweed and Forster on the North Coast -ARM NEWSDESK
