The Strikers are chasing consecutive titles in Saturday night's decider at Adelaide Oval, while the Heat won the most recent of their two trophies in 2019.
Adelaide secured home-ground advantage and direct passage into the final by finishing top.
The Heat had to win two knockout finals in Perth midweek to advance to a final to be played in cool but clear conditions.
Both teams have been forced to make one change after losing England players to international duty.
Adelaide allrounder Dani Gibson and Brisbane batter Bess Heath have departed to join England's tour of India.
The Strikers summoned another Englishwoman, Darcie Brown, who isn't among the touring squad, while the Heat called up Mikayla Hinkley.
Teams:
Adelaide Strikers: Tahlia McGrath (capt), Georgia Adams, Jemma Barsby, Darcie Brown, Katie Mack, Anesu Mushangwe, Bridget Patterson, Maddie Penna, Megan Schutt, Amanda-Jade Wellington, Laura Wolvaardt.
