The state government in Western Australia has announced the beaches where baited drum lines will be deployed next month to protect swimmers from sharks.
Drum lines will be set 1km from shore in the metropolitan area, at Ocean Reef, Mullaloo, Trigg, Scarborough, Floreat, City Beach, Cottesloe, North Cottesloe, and Port and Leighton Beaches.
In the South West, there will be drum lines off the coast at Old Dunsborough beach, Meelup, Castle Rock and Gracetown beaches.
The ABC reports the new Marine Monitored Areas will be patrolled from January to April.
Premier Colin Barnett said the new measures are necessary after increased shark activity in recent years.
"We have had 20 fatal shark attacks in WA in the past 100 years, seven of them in the past three years," he said on Friday.
