2018–19 Brisbane Heat WBBL season

The 2018–19 Brisbane Heat Women's season was the fourth in the team's history. Coached by Peter McGiffin and captained by Kirby Short, the Heat finished third on the WBBL|04 ladder and qualified for the playoffs. In an "incredible" semi-final notable for a catch taken by Haidee Birkett on the last ball of the game, they defeated the Sydney Thunder to progress to their first championship decider appearance. In the final against the double-defending champions, the Sydney Sixers, Player of the Match Beth Mooney led an upset victory to secure Brisbane's maiden WBBL title.
