A versatile swingman listed at 6 ft 7 in (2.01 m) and 220 lb (100 kg), Ducas plays the shooting guard and small forward positions. He began his career in the Australian state leagues before moving to the United States in 2019 to play college basketball for the Saint Mary’s Gaels. After five collegiate seasons, Ducas joined the Oklahoma City Thunder of the National Basketball Association (NBA) on a two-way contract and became a member of the Thunder’s 2025 NBA championship-winning team.
Early Life and Background
Alexander Ducas was born on 11 December 2000 in Geraldton, Western Australia, Australia. He was raised in the coastal city and attended Nagle Catholic College, where he first developed his basketball foundation. While in Canberra, he also attended Lake Ginninderra College, balancing high school studies with elite-level training.
Ducas grew up in a basketball-oriented household, with his father Aaron Ducas closely tied to the local game. That family connection to the sport helped shape his early work ethic and love for competition. As a teenager, Ducas also linked into the Basketball Australia Centre of Excellence pathway, which sharpened his skills against top-age peers and prepared him for senior-level play.
Path to Professional Basketball
Ducas debuted for the Geraldton Buccaneers in the State Basketball League (SBL) in 2016, averaging 2.27 points across 22 games as a 15-year-old. Over the next three seasons he steadily increased his production, averaging 5.67 points in 2017 and around 9.0 points in limited 2018 action, while also appearing for the BA Centre of Excellence in the South East Australian Basketball League (SEABL).
In 2019, his final pre-college year, Ducas erupted for 21.8 points, 3.6 rebounds, 1.4 assists and 1.0 steals per game in nine NBL1 appearances for the Centre of Excellence. He was named the NBL1 Youth Player of the Year and helped the Buccaneers win the 2019 SBL championship, finishing his Australian stretch with averages of 15.54 points, 3.92 rebounds and 3.08 assists. That summer, Ducas committed to Saint Mary’s College of California, launching his move to the United States.
Alex Ducas Career
Saint Mary’s Gaels (2019–2024)
Ducas debuted for the Saint Mary’s Gaels on 5 November 2019 against Wisconsin, recording 3 points and 2 rebounds. As a freshman he appeared in 33 games and started 11, more starts by a true freshman than any Gael since Matthew Dellavedova. A sophomore ankle injury limited him to 14 games, but he had been averaging 11.3 points on 35.7% three-point shooting before the setback.
As a junior, Ducas posted 10.3 points per game, and in his senior year he averaged 12.5 points while shooting 41.4% from beyond the arc. In his fifth and final season he started every game for the third straight year, shot a career-best 43.8% from three, and made 81 threes, the second most in the West Coast Conference that season and the ninth most in program history. He helped Saint Mary’s win the 2024 WCC tournament and earned second-team All-WCC honors for the second time. Ducas finished his Gaels career having played a program-record 150 games and ranking second all-time at Saint Mary’s with 278 made three-pointers.
Oklahoma City Thunder (2024–2025)
After going undrafted in the 2024 NBA draft, Ducas signed a two-way contract with the Oklahoma City Thunder on 16 July 2024. A back injury kept him out for nearly two months before he scored his first NBA points in January 2025. He appeared in 21 NBA regular-season games, averaging 1.7 points and 1.2 rebounds, while also playing six games for the Oklahoma City Blue of the NBA G League.
Although Ducas did not see playoff minutes during the Thunder’s 2025 postseason run, he was part of the championship squad and earned an NBA title when Oklahoma City won the 2025 NBA Finals. He became the ninth Australian-born player to be part of an NBA championship team. He later rejoined the Thunder for the 2025 NBA Summer League, playing one game in Salt Lake City.
Brisbane Bullets (2025–Present)
On 28 July 2025, Ducas signed with the Brisbane Bullets of the NBL for the 2025–26 season, returning home to Australia after his NBA stint. The move reunited him with the country’s top professional league and gave the Bullets a perimeter shooter with international and college pedigree. His contract with Brisbane is reported to run through the end of 2026.
Driving Style and Strengths
Ducas is best known as a high-volume, high-efficiency three-point shooter who thrives in catch-and-shoot situations. His combination of size and skill allows him to play both shooting guard and small forward, and his five years of college experience translated into a mature, team-first approach. He is valued for spacing the floor, moving without the ball, and providing steady secondary playmaking on the wing.
Notable Events and Milestones
Ducas’s signature collegiate moment came when he hit seven threes for a season-high 23 points against Davidson during his senior year. He also set the Saint Mary’s all-time games-played record with 150 appearances and finished second in program history with 278 made threes. In the NBA, his most meaningful milestone was earning a 2025 championship ring as a member of the Oklahoma City Thunder.
