AUSTRALIAN SEVENS TRIALS Canberra Olympic Games hopeful Tom Cusack will unleash four months of injury frustration on Monday as he launches his bid to win rugby sevens selection for Rio.
Cusack and a host of sevens players, including ACT Brumbies flyer Henry Speight, will get one last chance to impress coach Andy Friend when they play six games over three days.
Cusack and Speight have been out of action for extended periods as they battled injuries.
But Friend will be keeping a close eye on their progress at Narrabeen before he has to start cutting his squad.
Cusack had a wrist reconstruction in   February and hasn't played since, leaving him with an uphill battle to snatch a spot.
"To miss four months was annoying, but it was a good opportunity to get my body right, my mind right and hopefully power on to a successful campaign," Cusack said. "The squad has been playing well so that makes it tougher, but I've got my mind around that scenario and I'm in a pretty good head space to move forward and try to cement a spot.
"The Olympics has always been a goal of mine and everyone else in the squad as well. You've got to keep fighting through and push through to stake your claim. It's a pretty tense scenario."
Speight will play his first game since fracturing the bone above his left eye in a Brumbies clash against the Cape Town Stormers in   March.
The Fijian speedster had to have a titanium mesh screwed into the bone and must wear headgear for the rest of the year to ensure the fracture has fully healed.
Friend must weigh up the best combinations for Australia's hopes of chasing an Olympic medal and Speight's limited time with the team could count against him.
Friend said Speight would be released for Brumbies duties if he doesn't make the squad, but was hopeful the winger could get back to his best in the intra-team battle.
"He's looking really fresh and he's got a fair bit to prove as well, so that's exciting. I think he's going to go well," Friend said.
"We would release him, Brumbies are keen for Henry to play and so are the Wallabies. If he's not involved with us, we won't hold on to him. But at this point I hope he's going to be right.
"I'm really excited for Tommy, he's probably our fittest player.
He's as keen as mustard and I'm looking forward to seeing what he can do."
Friend will cut his squad of 24 to 16 for a trip to Darwin and then trim a further four players for the final Rio selection.
Speight made the switch to sevens after last year's World Cup, but his Brumbies duties and injuries have limited him to just two tournaments.
In contrast, Cusack has been in the sevens system for almost four years and turned down a chance to sign a Brumbies contract this year to pursue his Olympic ambitions before his wrist injury threatened to derail his hopes of making it to Rio.
"It's only natural to feel a bit of uncertainty when you want the best for your teammates and the best for yourself at the same time," Cusack said.
"You've got to put your hand up and say 'this is my chance'. I've never felt fitter ... you've got to let the reins loose and get firing. I'll be going out with an intent to stake a claim."
