The Melbourne United captain and Commonwealth Games-winning Boomer was the highest profile name on the list ahead of the official free agency period which begins next Wednesday, July 15.

Goulding, 31, who won the 2018 NBL Grand Final MVP, played 27 games in the 2019-20 season, taking his career total of NBL appearances beyond 300.

He is joined on the list by the likes of Anthony Drmic (Adelaide 36ers), Harry Froling (Adelaide 36ers), Cam Gliddon (Brisbane Bullets) and Todd Blanchfield (The Hawks).

Cluan's Adam Gibson, who turns 34 in October and has played 428 matches in his 15-year NBL career, remains contracted to South East Melbourne Phoenix.

Launceston's Lucas Walker, 35, who has 241 career NBL appearances, is a free agent having played 21 games with Sydney Kings last season.

Walker was a teammate and roommate of Goudling in the gold-medal-winning Commonwealth Games campaign of 2018.

NBL commissioner Jeremy Loeliger said: "The start of the free agency period marks an exciting time for the league as the teams finalise their rosters for the upcoming season.

"Due to the later start to the season of December 3, we pushed free agency back this year to allow teams more time to prepare."

Last week the NBL struck a deal with the Tasmanian government and issued the state a licence to take part in the 2021-22 season.
