Blair became a household name in 2001 when he finished runner-up in the first series of the reality show Big Brother. The national popularity he gained from the series and his interest in acting, which he’d dabbled in prior to Big Brother, was noted by casting agents and Blair was offered the role of Stuart Parker in Network Ten’s Neighbours.
He stayed as a cast member on Neighbours for 5 years until his character left the show, to hit the road, in April 2006. Neighbours’ massive following in the UK guaranteed Blair success with an international audience and he left Australia to take on opportunities basing himself in London.
He played the role of Dan in a West End play called The Vegemite Tales, competed in soccer trials for a reality program set around a celebrity team playing in England’s Sky One The Match, and was a celebrity participant in a documentary behind the scenes where he learnt about becoming a Safari Ranger, then as a member of the Paparazzi for a Magazine in “Deadline” a UK reality show.
On returning to Australia Blair was cast for Australian Drama including series character role in Sea Patrol 2009 and a guest role in City Homicide. He also returned to the UK to film his recurring role in episodes of Hearbeat. As a presenter and personality, Blair joined the 9 network as a regular reporter for Postcards as well as guest appearances on Big Questions, Singing Bee Celebrity Wheel of Fortune and 20-1.
