CTBAAU2S has no branch code, so it is the head-office (primary) BIC for Commonwealth Bank of Australia — the code international senders use for transfers to any of the bank's branches.
8 vs 11 Characters — Which Do You Use?
SWIFT codes come in two lengths. An 8-character code (like CTBAAU2S) identifies the bank's head office and covers all of its branches. An 11-character code adds a three-letter branch suffix that points to one specific office.
A common suffix is XXX, which simply means “head office” — so CTBAAU2S and CTBAAU2SXXX are equivalent.
In short: for almost all international transfers to Commonwealth Bank of Australia, the 8-character code CTBAAU2S is the right one to give the sender.
