Shark warning issued for Fairhaven beach along Victoria's Great Ocean Road

A shark warning has been issued for Fairhaven beach along Victoria's Great Ocean Road after a large whale carcass was found in the area.

VicEmergency issued the warning for Fairhaven and Moggs Creek just after 7am this morning, advising beachgoers to remain on high alert in the water.

Whale carcasses are known to attract sharks to the area, bringing them closer to shore than normal.

"Due to a large whale carcass there has been an increase in shark activity reported at Fairhaven today," the message read.

"While it is not uncommon for sharks to be present off the Victorian coast, you should exercise additional caution in the area."

The advice comes as Victoria braces for another heat wave, with temperatures set to rise to a top of 31 degrees today.

The warm weather is set to draw hundreds to the beach today, however beachgoers have been urged to remain vigilent.

"Stay informed and do not enter the water at closed beaches," the warning said.

People who see a shark should report the sighting by calling Triple-Zero or notifying lifesavers immediately.
