Before beginning his career in the NBL, Trahair attended the
Australian Institute of Sport in 1992 and 1993. He began his NBL career with the
Perth Wildcats in 1994, and was named runner-up to
Sam Mackinnon in the
Rookie of the Year award for that season. The following year, Trahair was a member of the Australian under 19's team that won silver at the Junior World Championships, and won his only NBL championship with the Wildcats. In doing so, he was a member of the Wildcats squad that travelled to the McDonald's Championship in
London that competed against the
NBA's
Houston Rockets and
Spain's
Real Madrid. In 1997, Trahair headed east to play with the
Sydney Kings where he remained until the conclusion of the 1999–2000 season. Over the next several years, Trahair played a series of short stints with numerous fledgling NBL clubs including the
Cairns Taipans,
West Sydney Razorbacks,
Hunter Pirates, and the
Singapore Slingers. Prior to the commencement of the 2007–08 season, the unsigned Trahair trained and appeared in several pre-season matches with the Wildcats while in Perth visiting family. Despite early reports that the Wildcats would not sign Trahair (as they held out for the possibility that American
forward Shawn Redhage would become an Australian citizen), the guard was officially signed up shortly before the first match of the season against his previous club, the Singapore Slingers. However, after appearing in just eight games with limited minutes for the Wildcats, Trahair was released by the club in December 2007 to allow him to sign with the
Wollongong Hawks for the remainder of the season. In 2007 and 2008, Trahair played in the
State Basketball League (SBL) for the
Rockingham Flames, then between 2009 and 2013, he played for the
Mandurah Magic. In
2015, Trahair served as an assistant coach for the Rockingham Flames men's team. In
2016, he served as head coach of the
Geraldton Buccaneers. Between
2017 and
2022, he served as head coach of the Mandurah Magic men's team. He was appointed the head coach of the
Kalamunda Eastern Suns men's team for the
2023 NBL1 West season. He continued as Suns coach in 2024 and 2025, and will again in 2026. ==References==
