The South Eastern Australia designation encompasses the southeastern third of the continent and was designed to include all major Australian wine regions outside of Western Australia. In practice the appellation allows Australia's giant export-driven wineries a free hand in blending vast quantities of supermarket wine from their holdings in South Australia, Victoria, and New South Wales.

This was particularly useful in that the majority of volume wines come from the arid interior irrigated by the Murray river and these regions technically straddle the three states. Though the odd exception does exist, this is the designation of choice for the Yellow Tail, Fish Eye, Alice White, and box wines of the nation, providing consistently reliable wines at shockingly low prices the world over.
