Seems to be a common Australian abbreviation. Only other place I've ever heard it (central business district) is on an Aussie TV show.

Yes was referring to 'central business district'.

And good to find out it's an Australia centric expression. Thanks.

CBD is an expression also used by Kiwis (New Zealanders).
