A year later, Guyett was on the move again as he teamed up with Wright at Chester City, where he was named player of the season in 2002–03 and then won a Conference championship medal a year later. But he opted to join Yeovil Town in the summer of 2004 and remained there until 2008, bar a loan spell with Aldershot Town in 2005. In May 2007, Guyett played at Wembley Stadium in the Football League One play-off final against Blackpool (making him the first Australian to play at the new Wembley).
He moved to AFC Bournemouth in the summer of 2008, at the age of 32, after being allowed to leave Yeovil Town by mutual consent. He was released two years later, and after a short spell with Dorchester Town, moved to Crystal Palace to work as the club's Fitness Coach.
