I used to live in Cottesloe. Used to swim at the North Cott beach where the attack you mention took place.
Of course the day of the attack it was overcast, calm, and just daylight. If you were hunting for hungry sharks, this is where you'd be. Not wise - yet unfortunate. It's not the only attack at north cott.
And it was a white shark.
Lucky you. My friend says basically the same thing about the area. Seems like it's *the* favorite hangout for sharks. It looks like a beautiful beach.
Thanks for the clarification on what kind of shark it was.
