The Heat will host the Sixers in the Wednesday's Big Semi Final at the Gabba after finishing second on the BBL ladder behind the Perth Scorchers.
It is the first time the Heat have hosted a BBL final in the six seasons the competition has been around for and comes off the back of four successive sold out games at the Gabba in 2016-17.
The Heat's WBBL team will also be in finals action this week after recording a heart-stopping super over victory over the Adelaide Strikers at the Gabba yesterday. The team will travel to Perth to play on Tuesday for their first taste of finals action having missed out on the top four in the WBBL's inaugural season in 2015-16.
