Where "Goon" Comes From
Cask wine — the box "goon" comes in — was a genuine South Australian invention. Riverland winemaker Tom Angove patented the bag-in-box design in April 1965, inspired by ancient flexible containers like goatskins. His key innovation was a collapsing plastic bladder inside a cardboard box, so no air gets in to spoil the wine as it empties — solving a real problem with the older glass flagons it replaced.
How "goon" itself came to mean cask wine specifically is less clear-cut, but it's now the standard, near-universal Australian term for it — inseparable from backyard parties, share-house budgets, and the drinking game "goon of fortune."

How Aussies Actually Use It
Used casually and often self-deprecatingly to describe budget wine at a party or gathering — "we only had enough for a goon bag" implies a tight budget rather than fine taste.
It's rarely used for anything resembling quality wine; the word itself signals the cheap, bulk nature of the drink.
