Was this the WORLD'S smallest bank?

In the small town of Shackleton, about 200km east of Perth, you will find what was (probably) the smallest bank in the world. Sounds crazy, but I couldn't any information to suggest otherwise. The structure was originally transported from Bruce Rock and was initially a branch of the Agricultural Bank. Over the decades, it has served as a branch for the Bank of New South Wales, R&I, and lastly, Bankwest, which closed in 1997.
