Canberra beat several NRL clubs to land Bateman's signature and paid an undisclosed transfer fee to Super League club champions Wigan in order to recruit the England international on a three-year deal.
Likened to England teammate Elliott Whitehead for the ability to play in the back row or as a centre, Bateman faces stiff competition in the Raiders forward pack with Whitehead, Iosia Soliola, Joseph Tapine and Josh Papalii to battle for starting positions.
The 25-year-old has been predicted to light up the NRL when he arrives on Australian shores in December.
