[4] A Papua New Guinea international representative hooker, Aiton played for the Penrith Panthers and the Cronulla-Sutherland Sharks in the NRL, and the Wakefield Trinity Wildcats, Leeds Rhinos and the Catalans Dragons in the Super League.

[5] After playing for Penrith's second-tier team, the St Mary's Cougars, in the NSWRL Premier League, Aiton was called upon to make his NRL début on 23 April 2006, starting at hooker for Penrith in their round 8 match against the Cronulla-Sutherland Sharks, as a result of an injury sustained by Craig Gower.

When the case was eventually concluded in 2016, Aiton had a twelve-month suspension recorded against his name, although he served none of the time due to backdating of the sanction.

On 5 August 2015, Aiton decided not to sign a new deal with the Leeds Rhinos, instead moving on to play for France's biggest rugby league franchise the Catalans Dragons.

Aiton said “I will always be honoured to have played for Leeds Rhinos but the opportunity to move to France from next season and be part of the Dragons was something that excited me at this stage in my career."
