The world's eyes, and noses, are on the outback central western Queensland town of Winton today for the Australian Dunny Derby.
Organiser Robin Stevens says she is amused that media outlets around the world are interested in the race of modified outdoor toilets.
She says there is more the $5,000 on offer to the team that wins the gruelling challenge.
"This race is run over a 250 metre track and the jockey has to dismount and pick up quite a number of objects along the way ... the winners go straight into the finals and the losers go into the constipation stakes ... and there's also a prize for the best presented team and outhouse and that's called the ass wipers' trophy - yes, ass wipers," she said.
Ms Stevens says there are 20 racing loos nominated for the event.
"They're not only locals, they've come from all over the state ... actually the RAAF boys from Townsville have put a loo in, there's two from the Gold Coast, there's one from the town of Miles ... they're set up on wheels, we get two pushers, two pullers and, of course, the jockey is seated on the thunderbox," she said.
