What’s the difference between a bank and a credit union?

Banks are for-profit financial institutions and credit unions are not-for-profit.

When members borrow and save with us, you’re funding our support of a variety of local community initiatives. We are a member-owned organisation that provides a financial service to cater for the needs of members. We offer great-value loans and free savings accounts for all members. As the name suggests, we put our members first.
