An Australian father in the fight of his life against motor neurone disease (MND) is raising funds in the hope doctors can one day find a cure.

Jordan Early, from Perth, was diagnosed five months ago and the disease has already ravaged his body, stealing his strength and speech.

But the 42-year-old is determined not to let it defeat him.

“MND is not incurable, it’s underfunded,” he told 7NEWS.

“If we can raise the money to keep pushing forward, we’ll solve this one day.”

The father-of-three has set himself the goal of raising $100,000 for research.

He is doing it through Jordan’s Big Freeze fundraiser, with a group of sporting greats including John Worsfold, Alicia Molik, Andrew Embley and Daisy Pearce to head down a slide into a pool of icy water on Saturday at Claremont Oval.

The sliding starts at 1.45pm, prior to the WAFL match between Claremont and Peel at 2.30pm. There will be special coverage on Channel 7.
