In a thrilling final quarter where the scores were tied in the dying moments, Bulleen star Liz Cambage made a lay-up to seal the win for the Boomers. Cambage had a 29-point, nine-rebound performance while Standard Life GB player, Jo Leedham added nine points to help her side get the chance to go for a second straight WNBL championship.
The Boomers now need one more persistent performance on March 11 to claim the championship title for the second time in a row.
The grand final is expected to be at the State Netball and Hockey Centre, but is yet to be confirmed.
