60 Years of Decimal Currency: A Quiet Revolution That Changed Australia
By Rajiv Chaudhri, Editor-in-Chief
On 14 February, Australia marks 60 years since one of its most practical yet transformative national milestones: the introduction of decimal currency. On that day in 1966, famously dubbed C-Day, the nation shifted from the complex pounds, shillings and pence system to dollars and cents, aligning Australia with a modern, global way of doing business.
Before decimalisation, everyday transactions required mental gymnastics. Twelve pence to a shilling, twenty shillings to a pound, hardly intuitive in a world moving rapidly towards simplicity and speed. The move to decimal currency, championed by policymakers and implemented with remarkable efficiency, replaced this with a clean base 10 system: 100 cents to the dollar. Overnight, calculations became easier for households, shopkeepers, students and businesses alike.
What made the transition remarkable was how smoothly it unfolded. Years of public education, catchy campaigns and careful planning ensured Australians were ready. Banks, schools and retailers adapted swiftly, while new coins and notes, produced under the guidance of the Reserve Bank of Australia, entered circulation with designs that reflected national identity, heritage and innovation.
Beyond convenience, decimalisation symbolised a confident, forward-looking Australia. It supported trade, strengthened economic literacy and helped integrate the country more seamlessly into international markets. Over the decades, our currency has continued to evolve, from paper notes to polymer banknotes pioneered right here in Australia, now adopted worldwide for their durability and security.
Sixty years on, decimal currency is so embedded in daily life that it’s easy to forget the scale of change it represented. Yet its legacy endures every time we tap a card, count change, or teach a child the value of money. It was a quiet revolution, one that helped shape a modern Australia and continues to serve us well in an increasingly complex economic world.
