He's expected to get a start against the US at Soldier Field in Chicago this weekend and knows he needs to make the most of his opportunity.
"It's a chance for me to showcase what I've got to offer to the coaching staff," Tomane said.
"I'm going to use it as an opportunity to force their hand a bit."
Tomane never doubted his ability to make the squad despite not locking down a regular starting spot while accumulating 15 tests over four seasons.
He has played just one of the Wallabies' four tests this year, starting against Argentina in Mendoza where he crossed for his fourth test try.
"I'm always confident in my abilities," said ex-NRL player Tomane.
"Since I've moved to rugby I've played a few tests every year, but haven't been able to lock down a starting role consistently."
The former Storm and Titans NRL winger said playing at the 2015 World Cup was a drawcard when he switched codes in August 2011.
His cause this season has been helped by a rare injury-free campaign highlighted by a hat-trick of tries in a Super Rugby qualifying final in South Africa against the Stormers.
"This year was probably the first season I've played every game, played close to every minute of Super Rugby," Tomane said.
"It's good to get through a season healthy."
