Australia Day will be celebrated in unique style in Western Australia's Kimberley region - with a cane toad race.
The race will take place at the Pinctada Kimberley Grande hotel in Kununurra, raising funds for the Kimberley Toad Busters, which claims to have humanely culled 2.4 million of the pesky critters.
The organisation also gathers scientific data about cane toads, helping to assist in the federal government's efforts to find a biological solution to the problem.
The first cane toad was found in WA five years ago and the species has been expanding its footprint much faster than many initially expected.
Pinctada Kimberley Grande general manager Mark Shanno said a large turnout is expected.
"We are expecting a full house on Australia Day, with some very enthusiastic support for the toads, but everyone in the Kimberley knows that the fight against the cane toad is deadly serious as they are a major threat to the region's pristine terrestrial and aquatic habitat systems," Mr Shannon said.
There will be several heats leading to a final race, with a grand prize of $500 going to the "ultimate toadie".
Competitors can bring their own toad, or buy them from Kimberley Toad Busters on the day, with a $10 entry fee for each race.
The toads will start competing from 3pm (WST) and the grand final is set for 5.30pm.
