A 23-foot great white shark was spotted off the Australian coast by a helicopter patrol.

The shark was seen about 330 feet offshore at the Marino Rocks in Adele last Sunday afternoon, a Shark Alerts South Australia Facebook post says.

Nearby Nippers events were cancelled and swimmers evacuated from the water.

‘It’s the biggest I’ve ever seen as a crew member in the Westpac chopper. We put it down as 7m the photo really doesn’t do it justice,’ an unnamed crew member wrote.
