[3] A Port Kembla local and Dapto junior, Simon made his first grade debut with the Steelers aged 17 and went on to make 120 appearances for the club between 1990 and 1995.
[5][6] His apparent lack of fitness found him out of favor with coach Brian Smith and midway through 1999 he gained another release to play for Auckland (he was named captain in his second match with the club).
He was selected at half-back for City Firsts in 1991 and 1992 and in game I of the 1992 State of Origin was picked in the run-on side when Ricky Stuart was unavailable due to injury.
During the 1997 season, split at both club and representative level due to the Super League war, Simon appeared in all three games, once at half and twice off the interchange bench.
Simon was the Blues' hero in game II, landing a 26-metre field goal in the 67th minute that clinched New South Wales' 1 point win.
