Juvenile bull shark hanging around Lennox Head

A SINGLE tagged bull shark is believed to be responsible for the repeated 'pinging' of a 4G shark detection buoy off Lennox Point in recent weeks.

The buoy was installed by the Department of Primary Industries last month as part of the NSW Government's $16 million shark management strategy.

In the last seven days it has detected the movement of a bull shark near the popular surfing break more than six times, including several times on Wednesday this week around noon.

A statement from the DPI confirmed that the multiple detections in recent weeks were from just one bull shark, 1.76m long.

The shark was one of two bull sharks tagged in the Richmond River in Ballina on February 3 by the DPI.

"The shark is not permanently lingering near the listening station, rather it has passed by it several times over the past few weeks," a DPI spokeswoman said.

"NSW DPI's bull shark research has shown that young bull sharks of this size range frequent the Northern Rivers region year round whilst larger animals tend to adopt a more predictable migratory pattern and travel north into Queensland for the autumn/winter and return again in late spring/summer.

"There are any number of reasons as to why this shark is frequenting the Lennox Head location, including the presence of abundant bait fish in the area coupled with optimal water temperatures.

"The data being provided by this animal is very useful scientific information about the natural movements of juvenile bull sharks that will help us better understand the behaviour of this species.

"DPI will continue to monitor shark movements along the North Coast and will continue to inform beachgoers of movement of sharks that pose a risk.

"The NSW Government has a number of measures in place to help reduce your chance of a shark interaction as part of its $16m shark management strategy.

"This includes aerial surveillance across this region during every day of the school holidays.  

"NSWDPI also encourages people to download the SharkSmart app for local information re shark sightings and incidents and follow us on Twitter @NSWSharkSmart."
