Before his departure from the Panthers and the NRL at the end of 2008, Rooney was part of City Origin, New South Wales and Australian rugby league squads.
In June 2010, Rooney signed a two-year deal with the Melbourne Rebels.[3] At Rebels' arrangement Rooney traveled to New Zealand in July to gain experience with Hawkes Bay in the NZ national provincial competition. However, he played only two games before being sidelined with a groin injury.[4][5]
Rooney's parents are English[4] and he holds a British passport.[6] In March 2010, while in negotiations with English club Worcester Warriors, he expressed ambitions to play for England in the 2011 Rugby World Cup.[6] He said he wants to play his very best rugby for the Rebels, but, "After that, who knows?" He added: "Of course it would be great to play for the Wallabies but I've got so much work to do before I can think of getting there."[3] In 2011 he rejoined Toulon.
