The son of Kevin and Lynne, Carey was one of five children who grew up in Wagga Wagga, New South Wales. His mother and father separated when Carey was aged six, with his mother taking four of the children to Adelaide, living in a homeless shelter. According to Carey's autobiography, his father was a violent man who had spent time at Mannus Correctional Centre and was troubled by alcoholism. A few months later, Kevin Carey retrieved the children from his estranged wife and they returned to Wagga Wagga.

For some time, it was unclear whether Carey would return to AFL football, but after the end of the 2002 season and a 12-month absence from football, Carey was signed by the Adelaide Crows where he played for the next two seasons.  Age and injury plagued Carey in 2003 and prevented him from dominating as he once did. He did manage to earn a top ten finish in the club best and fairest and kicked the second most goals of any Crow for the year, despite missing eight games. The 2003 season was most memorable for Carey's fiery encounters with his former North Melbourne teammates Glenn Archer and Anthony Stevens in round 6. On that day he kicked four goals, including one of the goals of the year. Carey's best performance for 2003 once again came in the finals, an elimination final against West Coast, when he had the most kicks and marks afield and became the 14th player to kick 700 career goals in AFL/VFL history.  Carey played the first 11 games in 2004, after which he had taken the most contested marks at Adelaide, was 11 goals clear in the Crows' goal kicking and was coming second in the club best and fairest. Carey's best performance in the Adelaide colours came a week before his 33rd birthday, in round 8 of the 2004 season. He took 9 marks, had 17 disposals and kicked 6 goals, out of a team total of 12, in a heavy loss to Essendon. Two weeks later, Carey's fourth goal against Hawthorn was one of the goals of the year. Taking a contested mark on the wing, Carey played on, having three bounces and shrugging off a tackle as he ran inside the forward 50. He gave off a handball to teammate Tyson Edwards, who in turn gave the ball back to Carey deep in the forward pocket. Carey's left foot snap for goal was a highlight in a big win for the Crows. In round 12, Carey left the field early in the second quarter and was later forced to retire with a disc-related neck injury, marking the end of a career that spanned 16 seasons and 272 games and included 727 goals.
