Turner collected the 400m (T36) gold today to add to his 100m win four days earlier.

Clifford dominated the 5000m (T13) final, with the help of sighted guides Philo Saunders and Tim Logan who both ran 6.1 laps each, to take gold after his 1500m win on the opening night of the nine-day titles.

They delivered Australia's seventh and eighth gold medals respectively. Along with shot putter Claire Keefer taking bronze in her F41 class, it was another three-medal haul for Australia, or in others words another solid day's work.

Turner arrived in Dubai with a revised plan from the London world championships two years ago, and executed it beautifully here.

And alongside his coach Iryna Dvoskina he won the 100m on Sunday and the 400m - both in world record times.

"I've done my job so I'm quite satisfied with that. The 51.71 seconds is a PB, great time, very happy with it," he said.

It was Turner's fifth gold medal from two world championship appearances and Australia's 7th in Dubai.

Keefer kept her remarkable world championships run intact with a bronze in the shot put (F41) on Thursday night.

And she made everyone hold their breath in the sixth and final round, when she let out her longest throw of the night 9.19m that moved her back into the medals.

On the track, wheelchair racer Rheed McCracken qualified for Friday's final of the men's 800m (T34) by placing third in Thursday night's heat (1m:52.07).
