Longmuir played a total of 17 games for Melbourne in 1998 and 1999, before being traded to Fremantle at the end of the 1999 season, in exchange for the club's second-round draft pick (#19 overall). There he made his debut for the club against Geelong in Round 1, 2000. He was a consistent player during the 2000–2002 seasons, however he dropped out of form in the following two years. Altogether, Longmuir played 55 games for Fremantle between 2000 and 2004. During this time, he was also a part of West Perth's 2003 WAFL premiership team, where he played when not selected for Fremantle.
