West Sydney Razorbacks / Sydney Spirit (2007–2009) Martin began his professional career with the
West Sydney Razorbacks of the
National Basketball League, but suffered a season-ending knee injury ten games into the
2007–08 NBL season. Following the
Sydney Kings' withdrawal from the NBL, the Razorbacks re-branded as the
Sydney Spirit for the
2008–09 season. Martin subsequently returned to the franchise for a second season. The Spirit quickly fell into financial difficulty and were saved from collapse mid season thanks to a rescue package from the NBL. The players and coaches all took significant pay cuts, with the entire team agreeing to live off just $150,000 between them to keep the franchise going—roughly $700 per week for Martin. Furthermore, Martin played much of the season with a broken wrist. In the 2009 off-season, Martin played for the Parramatta Wildcats in the
Waratah League.
Perth Wildcats (2009–2020) Martin joined the
Perth Wildcats for the
2009–10 NBL season. In his first season, he helped the Wildcats finish the regular season in first place with a 17–11 record and reach the NBL Grand Final. In the grand final series, the Wildcats defeated the
Wollongong Hawks 2–1 to win the
championship. In the 2010 off-season, Martin played for the
East Perth Eagles in the
State Basketball League. In the
2010–11 season, Martin won the
NBL Best Defensive Player Award and was named to the
All-NBL First Team. The Wildcats finished fourth with a 16–12 record and lost 2–1 in the semi-finals to the
New Zealand Breakers. In the
2011–12 season, Martin won his second straight NBL Best Defensive Player Award. He helped the Wildcats reach the NBL Grand Final series, where they lost 2–1 to the New Zealand Breakers. In the
2012–13 season, Martin won his third straight NBL Best Defensive Player Award. In January 2013, Martin was named co-captain of the Wildcats alongside
Shawn Redhage. He missed the 2013 grand final series with a partial tear of his Achilles tendon. For the
2013–14 season, Martin was named sole captain of the Wildcats. He won his fourth straight NBL Best Defensive Player Award. He helped the Wildcats reach a third straight grand final, where they defeated the
Adelaide 36ers 2–1 to win the NBL championship. On 14 May 2014, Martin re-signed with the Wildcats on a two-year deal (with the option of a third). In October 2014, he had a game with nine steals, the second most in club history behind
Ricky Grace's 10 in 1990. He was subsequently named Player of the Week for round three. He played his 200th NBL game during the
2014–15 season and won his fifth straight NBL Best Defensive Player Award. On 4 November 2015, Martin suffered a broken jaw and missing teeth following an errant elbow from
Townsville Crocodiles forward
Brian Conklin. He played his 200th game for the Wildcats during the
2015–16 NBL season. The team finished second with an 18–10 record and defeated the
Illawarra Hawks 2–1 in the semi-finals. In the grand final series, the Wildcats defeated the New Zealand Breakers 2–1 to win the NBL championship. Martin was named
Grand Final MVP. On 2 June 2016, Martin signed a new three-year deal with the Wildcats. He was sidelined early in the
2016–17 NBL season with a head and knee injury. He played his 250th NBL game in January. The Wildcats finished the regular season in third place with a 15–13 record, and played the second-seeded
Cairns Taipans in the semi-finals, a series the Wildcats swept 2–0. The series sweep advanced the Wildcats into the NBL Grand Final for the sixth time in eight years. In the best-of-five grand final series against the Illawarra Hawks, Martin helped the Wildcats win 3–0 to claim the championship. Martin played his 250th game for the Wildcats during the
2017–18 NBL season and won the NBL Best Defensive Player Award for a record-breaking sixth time. In the
2018–19 NBL season, Martin missed six games early with a low grade tear to his right calf muscle. Coach
Trevor Gleeson credited Martin's late-season form as one of the key reasons for the Wildcats riding a wave of momentum towards the finals. The Wildcats finished with an 18–10 record to claim the minor premiership, before going on to reach the NBL Grand Final series, where they defeated
Melbourne United 3–1 to win the championship. Martin and long-time teammate
Jesse Wagstaff became the first players in NBL history to win five championships with just one club. On 5 April 2019, Martin re-signed with the Wildcats for the 2019–20 season. In December 2019, he played his 300th game for the Wildcats. He missed the entire month of January with a left heel injury, returning for the final two regular season games. In March 2020, he was crowned an NBL champion for the sixth time, becoming one of just four players in NBL history to win six titles, with he and teammate Jesse Wagstaff the only to do it at one club. Following the season, it was revealed Martin had played through the year with an Achilles injury that required a post-season reconstruction. On 21 July 2020, Martin announced his retirement from basketball after 13 seasons in the NBL and 342 games. On 4 February 2024, the Wildcats retired Martin's number 53 jersey. ==National team career==
