Our History

In March 2025, we entered into a new phase of our journey through our merger with G&C Mutual Bank, creating one of Australia’s leading mutually owned banks.

Both G&C Mutual Bank and Unity Bank have proud histories and legacies in the communities and industrial sectors in which we each operate, and we share a strong alignment to member owned banking and delivering exceptional value in a fair and equitable manner.

Mutuality is deeply ingrained in both our DNA and through this merger we remain steadfast in honouring our origins and commitments, ensuring that our core values and promises to our members, employees and communities remain unchanged.
