More beach patrols after shark sightings

Helicopters will be deployed again to patrol popular beaches as shark sightings continue along Victoria's coast.

On Monday, Fairhaven beach was closed for four hours after a two-metre shark was sighted.

The latest sighting came after 32 sharks were spotted in waters near Anglesea and Fairhaven on Sunday.

With humid and hot conditions set to continue in Victoria on Tuesday, authorities are urging people to swim at patrolled beaches.

"We've got constant surveillance from the towers," Life Saving Victoria general manager Paul Shannon said.

Since the area has been a bit of a hot spot for sharks, the Westpac Rescue Helicopter will be deployed again to monitor conditions from the sky, Mr Shannon added.

Life Saving Victoria is patrolling 57 locations across Victoria between 10am and 6pm.
