Campion is one of 3 State of Origin representative products from Sarina State High School along with Dale Shearer, Wendell Sailor, and 4 from Sarina Crocodiles with Martin Bella. Campion made his début for the Gold Coast Seagulls in 1993, and went on to play 44 games for the club before signing with St. George for the 1996 season. He played in the in the Dragons 8-20 loss to Manly in the Grand Final at the Sydney Football Stadium. It would be his last game for the Dragons as he had signed to play for the Adelaide Rams in the new Super League in 1997. Campion joined the Rams and was one of the team's stand-out players in the club's first season. He would make his representative début for Queensland during the 1997 Super League Tri-series but sensationally was told by Rams coach Rod Reddy that he was not part of his plans for the club in 1998. After leaving Adelaide, Kevin Campion was then snapped up by Brisbane Bronco's coach Wayne Bennett, and went on to play 80 games for the club between 1998 and 2000, including the 1998, 2000 NRLGrand Finals. He scored a try for Brisbane in their 38-12 win over the Canterbury Bulldogs in the 1998 Grand Final. Campion then signed with the New Zealand Warriors in 2001 and went on to play at lock forward in their 2002 NRL Grand Final loss to the Sydney Roosters. At half time coach Daniel Anderson attempted to inspire the team by playing a mock commentary of the New Zealand Warriors scoring 'the greatest try ever scored'. Campion picked up the tape recorder, smashed it on the ground and gave the team an inspired speech instead. This made Campion one of only five players who have played in Grand Finals for three clubs during his career. Campion also represented Queensland on six occasions; four times in the annual State of Origin series, and twice in the Super League Tri-series. He also helped Ireland to the quarter-finals in the 2000 World Cup. At the New Zealand Warriors Campion was co-captain with New Zealand international halfback Stacey Jones.
