Where "Barcoo" Comes From
The Barcoo River drains the arid interior of western Queensland, flowing north-west from near Blackall before turning south to become Cooper Creek. Its name derives from the Birriya and Kungkari languages of the region. From the 1870s, "Barcoo" was adopted in Australian English as shorthand for the hardships and privations of remote outback life — a name that carried with it heat, flies, poor diet, and great distances from anywhere.
The phrase "Barcoo salute" — the hand-wave Australians use to brush persistent bush flies from their faces — is one of several compound expressions the word generated. Others include "Barcoo rot," a scurvy-like ailment from poor diet, and "Barcoo spews," a general term for heat-related illness. The salute is now more often called the "Aussie salute," as the habit of waving at flies is familiar well beyond the Barcoo itself.

"Out past Barcoo country, you'll need the Barcoo salute to keep the flies off."
How Aussies Actually Use It
"Barcoo" crops up mostly in the phrase "Barcoo salute," still a recognisable, good-humoured description of the constant fly-waving that comes with outback life.
On its own, it's used adjectivally to flag something as authentically remote or bush, in the same spirit as "beyond the black stump."
