"Cheers for that. No worries, mate."
Where "No worries" Comes From
"No worries" is first recorded in print in 1965, in Sydney's Oz magazine, already carrying its familiar relaxed, reassuring tone.
It went truly global through Australian pop culture exports of the 1980s and '90s — most famously Paul Hogan's catchphrase in Crocodile Dundee (1986) — along with soap operas like Neighbours and later Steve Irwin's Crocodile Hunter, cementing it internationally as shorthand for laid-back Australian friendliness.
How Aussies Actually Use It
"No worries" fills in for "you're welcome," "no problem," and "don't stress" all at once, making it one of the most flexible phrases in Australian English.
Variations like "no wuckers" — a cheeky euphemism — carry exactly the same reassuring, easygoing meaning, just with extra Aussie flavour.
