Shark sighting forces Western Australian triathlon swimmers out of water

Busselton Ironman 70.3 reduced to a duathlon after about 100 swimmers brought to shore

Dozens of swimmers at a triathlon in Western Australia's south had to be removed from the water after a shark was spotted.

Most of the individual competitors in the Ironman 70.3 in Busselton on Sunday had already completed their 1.9km swim when the shark was seen, but those who remained in the water were removed by Surf Life Saving WA and the beach was closed.
