Captain Tom Abercrombie has signed a one-year extension to his contract to remain with the team until the end of the 2022 season.
The 32-year-old forward debuted for the Breakers in 2009 and has spent his entire career with the franchise.
In that time he has played 303 games, won four championships and is the franchise's all time leading scorer, with 3450 points.
While the Breakers have gone through changes in recent times, prompting criticism and departures, Abercrombie supported the new direction.
''It is important for me as a player who's been here a long time to show that I'm 100% behind the changes at the club,'' said Abercrombie.
''I am 100% committed to what Dan Shamir and the team are doing and the direction the club is going.''
He admitted Shamir's arrival, replacing Kevin Braswell, was a key reason for the decision.
''I've only been playing under Dan for a month or so now, but I'm learning a huge amount.
''He's an incredibly smart coach who demands a lot from his guys, but I think the thing we are seeing is that his style relies on a lot of basketball smarts and experience.
''Those are the two things I bring by the truckload.
''I think it's a system that suits me very well, and Dan's coaching style suits me too.''
The Breakers have recently returned from the United States, where they played games against NBA teams the Memphis Grizzlies and Oklahoma City Thunder.
There Abercrombie made global highlight reels, throwing down a thunderous dunk on Memphis shot blocker Jaren Jackson Jr.
The team begins its national basketball league campaign on Friday night when it travels to play the Sydney Kings.
