Where "Your Blood's Worth Bottling" Comes From
The image behind the phrase is simple: someone so good that their very blood is worth preserving. The earliest recorded use dates to 1903, in a report of remarks overheard at a Western Australian football match.
It gained extra momentum with Australian soldiers in the First World War, appearing in a 1919 collection of "digger" slang, and it later doubled neatly as a slogan encouraging blood donation once blood transfusions became more common in the 20th century.
"Thanks for driving all that way to help us move — mate, your blood's worth bottling."
How Aussies Actually Use It
It's reserved for genuine, heartfelt praise — used when someone has gone well out of their way to help, and a simple "thanks" doesn't feel like enough.
It's given its own shorthand, "bottler," used to describe an excellent person or thing more generally, not just as part of the full phrase.
