Needing to chase down the Sixers' 7-131, in front of a sell-out crowd of 5,368 the Heat were in strife early, losing two quick wickets to be 2-14.
Opener and Player of the Final Beth Mooney (68) then took control at the crease with Captain Kirby Short (29), the pair combining for a strong partnership of 84 runs. The Heat then lost 5-28, bringing the Sixers back into the game at the death.
Requiring five off the last over the trophy was up for grabs for both clubs until Laura Harris smashed a boundary past deep mid-wicket to secure the WBBL|04 crown for the Heat.
Earlier in the day the Sixers did well with the bat as they set a solid total, with good scores from Ellyse Perry (33), Dane Van Niekerk (32) and Ash Gardner (23).
Off-spinner Grace Harris was the best with the ball for the day, with strong figures of 3-23 off four overs, Sammy-Jo Johnson (1-22) and Jess Jonassen (1-28) were the other wicket takers for the Heat.
Despite falling short in the end, the Sixers still impressed with the ball as pace bowlers Erin Burn (2-25) and Dane Van Niekerk (2-34) claimed important wickets.
