Where "Garbo" Comes From
"Garbo" applies the "-o" suffix to "garb-" (from "garbage"), following the same pattern as "servo" (service station), "arvo" (afternoon), and "smoko" (smoke break). The "-o" suffix in Australian English originated from nautical and street cries such as "smoke-oh!" and "milk-oh!" and developed into a general colloquialising suffix that conveys a robust, familiar tone. The word is first attested in Australian English in 1953.
The garbo occupies a respected place in Australian culture. In an old tradition that has largely faded, residents would leave Christmas gifts or beer for their garbo as a thank-you for a year's work — treating a necessary civic worker with the same warmth as a friend, consistent with Australian egalitarian values.

How Aussies Actually Use It
Used just as naturally as "garbage collector," and often as a reminder — "put the bins out before the garbo comes" is a phrase most Australians have heard growing up.
It's used affectionately, with no negative connotation, similar to how other trade nicknames function.
