The women’s race saw Great Britain Nicole Cook win from a breakaway group of five taking the sprint ahead of Trudy van der Straaten, with her teammate Peta Mullens rounding out the podium in third.
Cook credited her team, which also included 2010 Commonwealth Games road race champion Rochelle Gilmore, with the win.
“My teammate Peta (Mullens) won this event last year and she lead me out here and totally sacrificed her place for me,” Cook said.
For Cook the Subaru Cycling Grand Prix marked the beginning of her campaign to defend her Olympic crown in London.
“It’s a great start to the Olympic campaign,” she said. “I’ve had a break since the world championships and arrived in Perth a few weeks ago, where my brother lives.
“That (Perth) will be my base for the Australian summer and this is the first weekend of my pre-season training so it’s off to a very good start.”
