"That'll set you back about fifty bucks."
Where "Bucks" Comes From
"Bucks" originated in the United States, tracing back to early American frontier trade, where deerskins — "buckskins" — were commonly used as a unit of value in trade.
Australia adopted the term as an easy, casual synonym for "dollars" once the country decimalised its currency in 1966, and it's now used just as often as "dollars" itself in everyday speech.
How Aussies Actually Use It
"Bucks" gets used constantly in ordinary conversation about prices, wages, and costs — it's arguably more common in casual speech than saying "dollars" outright.
A "buck's night" (a groom's pre-wedding celebration) uses a related but separate sense of the word, worth knowing so context doesn't trip you up.
