Hailing from Australia, perhaps the most competitive sporting nation in the world, it is no surprise that the annual three-game State of Origin series is one of sport's fiercest rivalries.

The series sees players turn out for the state in which they were first registered to play Rugby League in Australia. With regional pride at stake the rivalry is fiercely intense. Since the inception of the series honours are incredibly even, Queensland have 38 victories to New South Wales's 37.
