Joel Selwood will represent Geelong when he plunges into icy waters for Big Freeze 6.

All 18 teams will have one player performing their own ice challenge, with the event raising much-needed funds and awareness to fight Motor Neurone Disease (MND).

The exact nature of each player’s challenge is yet to be revealed and will form part of a special presentation on Channel Seven on the Queen’s Birthday - June 8.

You can support Big Freeze 6 by purchasing a beanie online or from Coles and Bunnings stores nationwide.

FightMND is encouraging supporters to get involved by taking a selfie in their beanie and posting it to social media using the hashtag #FillTheG.

If you're really game, you can hold your own backyard Big Freeze and share your video using the hashtag #BackyardBigFreeze.
