Wollongong's Robert Hurley rediscovered his sparkling best by snaring two gold medals at the FINA World Cup meet in Doha on Saturday.
A member of the Australian team for the 2010 Commonwealth Games, Hurley put aside the disappointment of missing out on London Olympic selection when he won the men's 100-metre backstroke and 400-metre freestyle, his first titles of the series so far.
The 24-year-old former world record holder in the 50-metre backstroke for short course swimming, touched out Russian Stanislav Donets in the backstroke for gold in a time of 50.18.
Victorian Ashley Delaney came in fifth in 51.30.
Hurley was then dominant in the 400-metre freestyle, winning by more than a second and a half ahead of China's Kecheng Wang in 3:42.89.
Last year Hurley was seventh in the 200-metre freestyle at the Olympic trials in Adelaide.
Australians Tommaso D'Orsogna and Kenneth To dead-heated for gold in the 100-metre freestyle at the meet.
The pair touched the wall in a time of 47.10.
They were ahead of American Anthony Ervin while another Australian, Kyle Richardson, was fourth. With two gold medals presented for a dead-heat, they contributed to five golds for Australian swimmers on the opening night of the event in Qatar.
Rising 20-year-old To won his second with victory in the 100-metre medley final in a time of 51.58.
After winning the backstroke double in Dubai last week, Victoria's Rachel Goh had to settle for silver in the women's 50-metre backstroke.
She could not overtake Japan's Noriko Inada who took gold.
The next World Cup event is held in Stockholm this weekend. AAP
