The 2018 State of Origin series was the 37th annual best-of-three series between the Queensland and New South Wales rugby league teams. Before this series, Queensland had won 21 times, NSW 13 times, with two series drawn. The 2018 series was won by New South Wales, after winning the first 2 games of the series, their first since 2014, and their second since 2005.[1]
1 - In Game I, Billy Slater was originally selected at fullback for Queensland but had to withdraw due to an injury. He was replaced at fullback by Michael Morgan, with Anthony Milford coming on to the bench as a replacement.
2 - Greg Inglis took over the captaincy for the Maroons after the retirement from rep football of Cameron Smith. A thumb injury after Game 2 meant Billy Slater would take over the role for Game 3.
3 - Daly Cherry-Evans made his return to State of Origin, named for his first start at halfback since Game 2 of the 2015 series.
4 - Billy Slater would controversially be awarded with the Wally Lewis Medal for Player of the Series, despite only appearing in two out of the three games in a team that lost the series. The NRL changed the process for deciding the award the following year.
Scott Sorensen was originally selected at second row and captain for New South Wales but withdrew. He was replaced at second row by Dean Britt, with Bayley Sironen coming on to the bench as a replacement, and was replaced as captain by Kyle Flanagan.
The women's competition, which had in previous years been known as the Interstate Challenge, became known as the Women's State of Origin for the first time in 2018. The game was played on 22 June and was won 16–10 by New South Wales.[3][4]
