Burt made his first-grade debut in round 1
1999, at the age of 18 against the
St. George Illawarra Dragons. He was named the
1999 Parramatta Eels season's rookie of the year. Burt played on the wing in Parramatta's 18-16 preliminary final loss against
Melbourne during the same season. In the
2000 NRL season, Parramatta again made the preliminary final but were defeated by eventual premiers the
Brisbane Broncos 16–10 with Burt scoring a try during the game. Although a very capable fullback, Burt played most of his football as a wing or centre since the Eels backs of the era included
Clinton Schifcofske,
Brett Hodgson,
Wade McKinnon and
Jarryd Hayne, all of whom have earned at least one representative jumper at . As an outside back, he provided many tries down either the left or right flank for Parramatta. Burt played on the wing for Parramatta in their shock
2001 NRL grand final loss to the
Newcastle Knights at
Stadium Australia. In the
2005 NRL season, Burt played 23 games as Parramatta won the minor premiership and Burt's second at the club with the first coming in the
2001 NRL season. Burt played in Parramatta's shock 29-0 preliminary final defeat against
North Queensland at
Telstra Stadium. With the departure of McKinnon at the end of
2006 to the
New Zealand Warriors, Burt was installed as the regular fullback. In
2007 Burt continued his great form at fullback and was particularly impressive with his goalkicking, kicking at just under 90% success rates for the season. His form put him at the top of the NRL's point scoring list for much of the
2007 NRL season. Unfortunately Burt dislocated his kneecap against the
Newcastle Knights in round 17 and missed the remainder of the
NRL season. At the time of his injury, Burt was so far ahead on the point scoring list that it took
Hazem El Masri (second highest point scorer after Burt) until Round 22 to catch his total of 154 points for the season. In the middle of the
2009 season, Burt moved to the wing to let Jarryd Hayne move to his preferred fullback position. This move proved to be a masterstroke as Jarryd Hayne collected a number of awards including Dally M player of the year and fullback of the year and lead Parramatta to a
Grand Final against the
Melbourne Storm. Burt was unsuccessful in his second Grand Final appearance going down to Melbourne. Burt,
Nathan Cayless and
Nathan Hindmarsh were the only players to have played a Grand Final for Parramatta in the 2009 team. In round 4 of the
2011 season against the
North Queensland Cowboys, Burt broke
Brett Kenny's record of most tries for Parramatta with 111. In 2011, Burt was moved back to fullback due to
Jarryd Hayne going into the position of 5/8. With
South Sydney halfback
Chris Sandow joining the Eels in
2012, Eels coach
Stephen Kearney announced his intention to move Hayne back to his preferred fullback spot with Burt moving back onto the wing. Burt was an unceremonious 11th hour demotion to the
NSW Cup for the Round 2 match of 2012 against the
New Zealand Warriors. Burt announced that he would retire at the end of the
2012 NRL season and join the Eel's coaching staff in 2013. Burt's final game as a player came in round 26 2012 against
St. George Illawarra at
Telstra Stadium which ended in a 29–8 loss. ==Coaching career==
