Dane Swan and Lauren Jackson are the first two nominations from Neale Daniher for Big Freeze 5 at the MCG on Queens Birthday.
The Brownlow Medalist and six-time WNBL champion will be joined by a host of other sporting personalities to enter the ice bath.
"He's a bit of a rascal isn't he?" Neale said on Channel 7.
"So he'll be a bit of fun, Swanny."
