The event follows a near-miss where Perkins was run off the road by a truck while training at his Adelaide base.
Last week, Perkins told Cyclingnews that he is hoping to emulate his 2011 achievements at the 2012 championships, where he'll be competing in the sprint, team sprint and keirin.
"You always go into a race no matter how you're feeling or where your form is at trying to win and there is always a way to win, no matter what condition you're in," Perkins said.
