Henley-on-Todd Regatta in Alice Springs
Competitors race bottomless boats down the dry, sandy bed of the Todd River, running the course themselves inside hull frames with no water in sight. This fundraising novelty event in Alice Springs also features a sand-ski contest, a human hamster wheel and a comic mock naval battle.
Bottomless boats race down a dry riverbed in the middle of the desert at this deliberately absurd event, one of Central Australia's best-known spectacles.
