Swimming sensation Will Martin has smashed his own world record twice to claim his third gold medal at the Tokyo Paralympics.
Martin, who had already won the 400m freestyle S9 and was part of the 4x100m freestyle relay team that claimed the world record when winning their event, dominated the S9 100m butterfly on Thursday.
He was the only swimmer in qualifying to better one minute, clocking 58.14 seconds to break the world mark of 58.28 he set earlier this year on the Gold Coast.
The 20-year-old then went quicker in the final, clocking 57.19 and beating silver medallist Simone Barlaam of Italy by 2.24 seconds as fellow Australian Tim Hodge took fifth place.
Also on Thursday night, Ben Hance set a Paralympic record when won gold in the S14 100m backstroke.
Hance clocked 57.73 seconds, just shy of the 57.56 world record he set at the June national trials in Adelaide.
The 21-year-old had set a Games record of 57.75 in qualifying.
Australia has now won 15 gold medals in Tokyo.
