Commerce Permanent Building Society
The Commerce Permanent Building was located in the southern part of New South Wales. I am lead to believe that it became part of the NSW Permanent Building
Society.

The Commerce had three locations that I could find and are listed here.
Griffith: 372 Banna Ave
Tumut: 60 Wynyard St
Wagga Wagga: 186 Baylis St
