"It is only a training camp. That's just the way I feel about the game. That's it, that's life. What do you do?"
Australia coach Michael O'Connor was thrilled to include the professional trio, who have all already played sevens for Australia.
"All three of these guys have excelled in sevens and the fact that they're available ... we would be mad not to take them," O'Connor said.
"They're quality players and we would have liked them to have remained in the sevens programme to begin with.
"So to have them back in the squad for the World Cup is a great opportunity.
"We've got a lot of great leaders in this squad, and experience is critical at this level."
The squad has four members of Australia's silver medal-winning 2010 Commonwealth Games side, including in-form five-eighth Foley, and only two players with previous sevens World Cup experience.
Seasoned campaigner Ed Jenkins returns from a shoulder injury to lead the forward pack and the side in Russia, where his side faces France, Spain and Tunisia in pool play.
It will be former Gold Coast Titan Shannon Walker's first sevens World Cup.
