North Cottesloe Surf Lifesaving Club members Mathilda Lipscombe and Matthew Bailey will strip off in the Perth CBD tomorrow for a good cause.
Those trusted to keep Perth's beaches safe will hit the city streets to shake tins to raise cash for lifesaving equipment while wearing their distinctive red and yellow uniforms.
After joining the club in 2005 on the advice of his parents who thought it would be wise for their son to get accustomed to the beach, Mr Bailey said fundraising was an integral part of keeping people safe each summer.
"We need to have adequate equipment and enough people power to save lives and make sure everyone's safe on our beaches," he said.
Surf Life Saving WA marketing executive Maclain Bruce said clubs hoped to raise $75,000 in the street appeal, also held in shopping centres around Perth.
The money will be spent on much-needed equipment such as rescue boards, which cost $1300 each, rescue boats ($18,000) and defibrillators ($5000).
Mr Bruce said clubs got some State Government funding but many people were surprised that such a well-known organisation relied so heavily on donations.
"We are the face of WA's beaches," he said.
"Yet we are a charity that provides a valuable service to millions of people each year on and off the beach at no cost."
Last summer, 17 people drowned off the WA coast, compared with eight in the summer of 2011-12.
