Where “Dacks” Comes From
“Dacks” (also spelled “daks”) is Australian slang for trousers. Green’s Dictionary of Slang marks it as originally Australian and explains that Daks began as a brand name, patented in 1933 by the London clothiers Simpson’s for men’s trousers with a self-supporting waistband. Green’s adds that the brand name was supposedly an elision of “dad’s slacks”.
The earliest dated uses in Green’s are from Barry Humphries’ Barry McKenzie comic strip (1963–74), in the phrase “drop the daks”. It’s nearly always plural, so you’ll hear “a pair of dacks”.

How Aussies Actually Use It
It’s casual and a little cheeky. You’ll hear it in family talk (“Put your dacks on!”) more than in a shop or an office.
In Real Life
Dacks are an Australian kitchen-table word: kids lose their dacks in the pool, adults complain about a hole in their dacks, and mates dare each other to “dack” someone. The word is cheeky and informal, so you’d use it with family and friends, not in a job interview. If you’re buying clothes, you’d say “trousers” or “pants” in the shop.

Good to know: You’ll see it spelled “daks” as well. Aussies use it for any trousers, not just the brand. “Dacking” someone, pulling their trousers down as a prank, comes from the same word.
