Is making as much money as he can his primary concern? He's suited up for the Boomers here at the risk of further injury. Even the guaranteed money on his rookie deal would be more than the career earnings of pretty much any Aussie who doesn't crack the NBA.
I don't know Dante, so I may be way off base, but the way he was so involved during the World Cup lead up was really striking. You had Simmons and Bolden having their massive drama public tantrums, and meanwhile this guy who literally can't go is hanging out at camp, basically just doing whatever he can in and around the group. He just seems like someone who isn't content with what he's done.
