Surf Life Saving WA tweeted that the whale was first spotted ’25m off City Beach, 500m south of the groyne’.

The shark was soon spotted following it.

‘Reports of 4m shark in vicinity to the whale,’ it added.

Several Perth beaches, including City Beach, Scarborough, Brighton and Trigg, were closed as the beasts swam north and have now been reopened.

It’s just a day since the state government’s shark catch and kill policy ended and controversial drum lines – set one kilometre off the coast – were removed.
