A GROUP of Water Police has been forced to wait 10 minutes underwater while a 4m great white shark

circled above.

The divers were at 18m, on a training exercise at Grange tyre reef, when the shark appeared near a

boat above them.

They remained in radio contact with boat crew until given the all clear to surface.

The divers were wearing Shark Shield, an electronic shark protector vest. The incident, on Monday, is

one of four shark sightings this week.
