Normally a centre, Mogg was selected as a wing for Queensland for games II and III of the 2006 State of Origin series; he was included after Greg Inglis was replaced due to injury. Mogg scored two tries on his Origin debut and a further try in game III. He was one of the oldest players to make an Origin debut.[4]
Mogg was selected to play for Catalans at stand-off in the 2007 Challenge Cup Final in which the Dragons were defeated by St. Helens 30–8.[5] He was selected at centre in the 2007 season's Super League Dream Team. The Queenslander grew in confidence in 2008, and in May 2008 signed a contract extension which tied him to the Dragons until 2011. In Perpignan he played the majority of his rugby at centre, but also played at stand-off.
On 22 March 2010 it was announced that Mogg had been released from his contract and would rejoin Canberra Raiders.[6][7]
Mogg retired from the game at the end of 2010, scoring only one try for the season.
