Mortgage Business 03 February 2021 The customer-owned bank has announced that it is to start trading under a new name and call itself a bank by the end of the year. Credit Union Australia (CUA) has announced that it will begin trading under a new name, Great Southern Bank, as it moves to cater to a younger audience. CUA’s CEO, Paul Lewis, said the bank had conducted research which showed that it needed to change its name from a ‘credit union’ to a ‘bank’ due to younger adults not having a strong understanding of what a credit union was or how it operates.
