A Manly junior who made his first grade debut for the Sea Eagles from the bench in Manly's 28-10 loss to Penrith at Penrith Park on 18 April 1981. Eden only played two first grade games for Manly in the 1981 season, the other saw the Sea Eagles come away with a 22-15 win over defending premiersCanterbury-Bankstown Bulldogs at Manly's Brookvale Oval. The 1982 season saw Eden play 19 games for the Sea Eagles playing mostly at fullback due to the emergence of teenage halfback Phil Blake and injury to champion Manly fullback Graham Eadie. Eden would be the Sea Eagles top point scorer for the year, scoring 2 tries and 71 goals for 148 points. Eadie returned late in the season and resumed the fullback role with Eden missing the Sea Eagles run to the Grand Final where they ultimately lost 21-8 to Parramatta. During the season, Eden was named the player of the series in the 1982 KB Cup won by Manly for the first time. Eden's form in 1982, plus his goal kicking and utility value saw his name touted as a possible selection for the 1982 Kangaroo Tour of Great Britain and France. However, missing Manly's late season games and finals campaign would prove costly and he ultimately missed out on a place in the Australian squad for the Kangaroo Tour. With Eadie back for the 1983 NSWRFL season, Eden signed to play for Eastern Suburbs and would become the season's leading point scorer, scoring 256 points. He also won the competition's Best and Fairest award, the Rothmans Medal, in 1983. Eden later said, "Manly eventually told me they weren’t going to be able to go anywhere near what they were offering over at the Roosters, but that they’d still love me to stay. I just said, 'Look, you've offered me three grand, the Roosters have offered me 25 … I’m newly married and got a kid on the way … a university wage, help me out here.' So I signed with the Roosters.' After an injury interrupted 1984 season where he scored 96 points playing only 13 games mostly at fullback or, he signed with Parramatta for the 1985 season. He would spend 3 injuries interrupted seasons with the Eels, playing only 27 games for the club and like he had done in 1982 with Manly, he missed the Eels charge to the premiership in 1986. Eden signed for new club the Gold Coast Giants in 1988. That season saw him play 19 games for the club where he would be the team's leading point scorer with 79 points and had the honour of scoring the club's first ever try in their opening game of the season against Canterbury-Bankstown. He played a further 12 games in 1989 for the poorly performed Giants and was again their leading point scorer with 63 points before announcing his retirement at the end of the season. Mike Eden played 112 first grade games in his career. A player of rare ability who could kick both in general play and for goal with either feet with equal effectiveness, he scored a total of 701 points from 26 tries, 296 goals, and 7 field goals.
