Diver killed by shark off Busselton in Western Australia
A MAN killed by a shark off Western Australia's southwest coast was diving with his brother, police say.
The man was diving about 200m off Stratham Beach in Geographe Bay about 230km southwest of Perth, when he was attacked just before 9.30am (WST) today.
A police spokeswoman said it was believed the man was diving with his brother, who was not harmed.
The body has been taken south to Port Geographe Marina in Busselton.
Beaches in the area have been closed following the attack.
Experts from the Department of Fisheries have launched an investigation, which will include an examination of bite marks on the man's body to determine what species of shark was involved in the attack.
An aerial patrol was to be sent out to try to determine if the shark was still in the area.
Today's attack is the fourth fatal shark attack off the WA coast since September last year.
