The 2009–10 season was Brisbane Roar's fifth season in the A-League. For the first time, Brisbane Roar was not the sole representative from the state of Queensland, being joined by Gold Coast United and North Queensland Fury. The addition of the new clubs and a change of ownership of the Roar have led to the club changing its name from Queensland Roar to Brisbane Roar. The change of ownership also brought about notable changes in the clubs' administrative ranks. Peter McLennan became CEO in place of the retiring Lawrence Oudendyk, while Chris Bombolas took the role of club chairman in June, which had been vacant since the departure of John Ribot in March 2008. Brisbane Roars owners increased membership and ticket prices leading to a decrease in crowd figures for the 2009–10 A-league season.

After last years initial success, the Roar Roadshow continues with fan days and trial matches against various clubs in the Brisbane area. However, drought-breaking rains in the South East took their toll, with multiple games cancelled or postponed due to waterlogged pitches. Queensland Roars Against Racism again, with Scottish giants Celtic F.C. becoming the highest profile club to ever challenge for the international invitational Translink Cup. The A-League Pre-Season Challenge Cup has been abolished, allowing A-League clubs to organize their own pre-season fixtures with one another.
