In 2012, Big Sky was merged with Australian Unity to become the banking arm of the company.

It was formed as the Manchester Unity Independent Order of Oddfellows (MUIOOF) in Melbourne, Victoria, on 7 December 1840 by eight men including Thomas Strode, publisher of the Port Phillip Gazette and Augustus Greeves, inspired by Independent Order of Oddfellows Manchester Unity.

[1] Australian Unity has about 8,500 employees across healthcare, insurance and banking (in the guise of Big Sky Credit Union) divisions.

[7][8] Another Melbourne building, formerly owned by Manchester Unity Oddfellows, at 335–347 Swanston Street was compulsorily acquired by the Commonwealth government in 1947.

[9][10] The building, constructed in 1940–41, sits opposite the State Library of Victoria, adjacent to the Melbourne Central shopping centre.
