Macquarie Credit Union is a customer-owned bank, which means that it is owned by its members rather than by shareholders. Macquarie Credit Union was formed in December of 1964 by electricity workers of Macquarie County Council.
Although only employees of the Macquarie County Council were permitted to join when the credit union was established, this rule has since been changed to offer membership to everyone residing in the local government areas of Narromine, Gilgandra, Warren, Cobar, Coonamble and Nyngan.
