8 vs 11 Characters — Which Do You Use?

A common suffix is XXX, which simply means “head office” — so CUAIAU4B and CUAIAU4BXXX are equivalent.
In short: for almost all international transfers to Credit Union Australia Ltd (trading as Great Southern Bank), the 8-character code CUAIAU4B is the right one to give the sender.
