Upwards of 1500 swimmers are expected to line up for Rip View Swim Classic on Saturday December 30.
"It's great timing this year, just betwen Christmas and New Year when a lot of people are in town, so we're expecting good numbers," said Point Lonsdale Surf Life Saving Club president Mathew Ponsford.
"I would expect the big guns to be in it again because they use it as a training swim before the Pier to Pub."
Commenced by social swimming group the Gruesome Groyne Gropers in 1989, the event – initially called the “Springs to Swings Classic” - is now one of the biggest open water swims in the state, boasting 1.4 and 3.8 kilometre courses. It is also the PLSLSC's biggest annual fundraiser.
Registrations are open for both swims
