Turner surged home to win silver on Saturday in Tokyo, but was visibly annoyed he didn't collect a second gold after his 400m title.

The 25-year-old from Wollongong was hot favourite for the double after entering the sprint final as world record holder and fastest qualifier.

The unsettled field was re-set before Malaysian athlete Mohamad Puzi, who was in the lane next to Turner, moved on the line which put the Australian off.

After his poor start Turner powered through the field to land a silver behind China's Deng Peicheng in a time of 11.85, well off the Australian's world mark of 11.72.

Turner slapped his thigh and shook his head in disappointment after the race.

Australian officials considered lodging a protest but it would have likely only seen fourth-placed Puzi disqualified rather than a re-run.

Turner said he only had himself to blame.

"I absolutely let myself get distracted," Turner told Channel Seven.

"I saw movement next to me and my body wanted to go with it and I let it so I've really got to put the blinders on for next time.

"It was my mistake to let that get to me and I've got to learn from it."

On Saturday night, Deon Kenzie landed bronze in the men's T38 1500m.

Canada's Nate Riech burst away and comfortably claimed victory, setting a Paralympic record (3:58.92) but Kenzie, the Rio silver medallist, made a burst for second midway through the race.

The 25-year-old Tasmanian was overtaken late by Algeria's Abdelkrim Krai but held on for a medal with a time of 4:03.76.

Fellow Australian Daniel Bounty finished sixth.

Nicholas Hum then won bronze in the men's long jump T20.

Hum's huge leap of 7.12m had him perched second behind gold medallist Abdul Latif Romly (7.45m) before Greece's Athanasios Prodromou landed 7.17m on his second-last attempt to claim silver.

Samantha Schmidt came sixth in the women's discus throw F38, while Rhiannon Clarke finished seventh in the women's T38 400m.
