I don’t recall ever having heard it. The OED lists it as “Austral. and N.Z. slang,” and all the cites appear to be from downunder. But it also gives four different pronunciations, British, U. S., Australian, and N. Z.
Urbandictionary.com has a single entry that says its Australian and gives an Australian example (identifiable as such by the cliches, “Sheila” and “throw a sausage on the barbey,” which probably means it was written by a non-Australian.)
