BCCM member RACQ is the first motorist club in the world to launch a mutual bank: RACQ Bank.
The move to open 13 branches comes following RACQ's merger with QT Mutual Bank in 2016.
RACQ's 1.6 million members will now be able to access to their own, member-focused banking service.
BCCM CEO Melina Morrison said the move shows the way forward to greater competition for the banking sector.
