After impressing at the Catalans Dragons, Dobson attracted the attention of several other Super League clubs, subsequently being signed by the Wigan Warriors in May 2006. There was some controversy over Dobson's signing for the Wigan Warriors. Under English law, Dobson was not permitted to play in England because he did not have a work permit. However, the Wigan Warriors managed to obtain a work permit for him, albeit in controversial circumstances.[6] When Dobson signed for the Wigan Warriors, they were at the bottom of the Super League table, 6-points behind the nearest team and heading towards relegation. Dobson's impact at the Wigan Warriors helped the team survive relegation in the 2006 season.
Dobson started playing for Newcastle in the 2014 NRL season. Dobson played for the Knights in the inaugural Auckland Nines series prior to the 2014 NRL season in February 2014. With an injury to the Newcastle Knights regular Jarrod Mullen, Dobson made his top-grade début for Newcastle in their 30–8 defeat by Penrith Panthers. Dobson made 25 tackles in the game, the third highest on the day for the Newcastle club. Dobson also played against his former club Canberra Raiders (in a 20–26 defeat), Melbourne Storm (in a 28–20 defeat), Cronulla-Sutherland Sharks (in a 30–0 victory), North Queensland Cowboys (in a 28–2 defeat) and Brisbane Broncos (in a 48–6 defeat).
On 21 September 2014, Dobson was named at halfback in the 2014 NSW Cup Team of the Year.[18]
Salford Red Devils
On 22 May 2014, it was reported that the Salford Red Devils of the Super League, had recruited Dobson for the 2015 season. In the match report following Salford's 4–25 defeat by the Wigan Warriors, it was reported "Salford will have re-inforcements next season with former Hull Kingston Rovers player Michael Dobson arriving from Australia after a far from happy time in the NRL."[19]
On 16 June 2014, Dobson officially signed a four-year contract with the Salford club starting in 2015.[20]
Coaching career
After returning to Australia to play for the Wynnum Manly Seagulls,[21] Dobson spent some time coaching in the junior ranks with the club, before taking up an opportunity at the Newcastle Knights.[22][23]
