Australia's currency is one of the most advanced in the world. The nation's banknotes are totally waterproof, hard to counterfeit, and relatively cleaner and more hygienic because they are resistant to moisture and dirt. The switch from paper to polymer currency occurred between 1992 and 1996, with Australia becoming the first country in the world to issue polymer banknotes in 1988 to coincide with its bicentennial year. By 1998, all Australian banknotes were issued in plastic. The move to polymer banknotes was made to increase security against counterfeiting and to increase durability.

What You'll Learn
The first polymer banknotes were issued between 1992 and 1996
Australia's currency is one of the most advanced in the world. The nation's banknotes are waterproof, durable, hard to counterfeit, and relatively cleaner as they are resistant to moisture and dirt. These banknotes are made of a polymer, which gives them a waxy feel. Polymer banknotes tend to last two to three times longer than paper notes, reducing replacement costs.
The Reserve Bank moved to polymer to enhance the security of the banknotes, which had been compromised by modern reprographic equipment. Polymer banknotes are more secure against counterfeiting and have many security features not available in paper banknotes, including the use of metameric inks.
Polymer banknotes are also more durable than paper banknotes and can be recycled at the end of their useful life into a range of plastic products. The longer life of polymer notes more than offsets the slight increase in cost.

Polymer notes are more durable, secure, and hygienic
The Reserve Bank of Australia, in collaboration with the Commonwealth Scientific and Industrial Research Organization and the University of Melbourne, was the first to develop polymer banknotes. The first polymer banknote was released on 27 January 1988, marking the world's first fully circulating polymer banknote. By 1998, all Australian banknotes were issued in plastic.
Polymer notes are made from synthetic polymer substrates (polypropylene) that consist of chains of joined individual molecules or monomers. The use of polymer makes the notes more durable than paper. The wear and tear typically associated with paper money do not affect polymer notes as quickly. The Guardian stated in 2013 that polymer banknotes are likely to last 2.5 times longer than paper money. Polymer notes are also less susceptible to dirt and bacteria, making them more hygienic and easier to clean.
Polymer notes are also more secure. The three-dimensional structure of the polymer allows for high-tech security features. The detailed images and the use of expensive technology make polymer notes harder to forge than paper banknotes. Countries that have adopted polymer banknotes have reported a remarkable reduction in counterfeiting.
Polymer notes are recyclable. The shredded polymer notes can be recycled into products like pens and flower pots, reducing environmental impact.

They are also recyclable
Australia's currency changed from paper to plastic polymer between 1992 and 1996, with all banknotes being issued in plastic by 1998. The country became the first in the world to convert from paper to polymer currency.
The shift to polymer banknotes was driven by the need to enhance security and combat counterfeiting, which had been on the rise due to advancements in reprographic equipment. Polymer banknotes are also recyclable, contributing to their environmental benefits. At the end of their useful life, they can be recycled into various plastic products. This recyclability, coupled with their durability and resistance to dirt and diseases, makes polymer banknotes a more environmentally friendly option compared to traditional paper currency.
The development of polymer banknotes in Australia was a significant innovation, attracting global attention. By 2009, Securency, a joint venture between the Reserve Bank of Australia (RBA) and Innovia Films, was exporting these banknotes to 25 countries, with over three billion polymer notes in circulation.
The world's first plastic banknote was the result of the collaboration between Dave Solomon and his team at CSIRO, the Commonwealth Scientific and Industrial Research Organisation. The $10 commemorative Bicentennial note, issued in 1988, was the first plastic film note with optically variable devices (OVDs) protected by clear plastic films on both sides. Solomon received numerous accolades for his contributions to science and technology, particularly in polymer chemistry.
The introduction of polymer banknotes in Australia marked a significant milestone in the country's currency history, offering enhanced security, durability, and environmental benefits through their recyclability. This innovation continues to shape the global currency landscape, with Australia leading the way in adopting and exporting this technology.

Polymer notes were invented by Dave Solomon
Australia's currency changed from paper to polymer between 1992 and 1996, making it the first country in the world to do so. The switch was made to improve security and make the currency harder to counterfeit.
Polymer notes were invented by Australian chemist and CSIRO chief research scientist Dave Solomon. Solomon led a team that combined optically variable devices (OVDs) with a thin polymer base. OVDs are security features that change with light or movement, such as holograms that appear as three-dimensional images and pictures that change colour.
The development of polymer notes began in 1968, when the CSIRO and the RBA commenced a 20-year "bank project" to develop a new form of currency that would be more secure and less susceptible to counterfeiting. The project was prompted by the emergence of high-quality forgeries of Australia's new decimal currency, which had been introduced in 1966.
Solomon's team developed a unique plastic film that could be printed on using conventional methods. The film was then enhanced with security features such as holograms and clear windows, which made the notes even more secure.
The first polymer notes were issued in Australia in 1988, as a limited edition for the Bicentennial year. The public readily accepted the new notes, and by 1998, all Australian banknotes were issued in plastic. For his contributions to the development of polymer notes, Solomon received numerous awards, including being made a Member of the Order of Australia in 1990 and elected a Fellow of the Royal Society London in 2004.

They were first suggested in 1967
The switch from paper to plastic currency in Australia was suggested in 1967 due to the increasing counterfeiting of the new state-of-the-art security banknotes that had been introduced in 1966. The new paper notes had security features such as watermarks, metal threads, and intaglio (raised print) printing, but forgeries of the $10 note appeared within a year.
Dr HC (Nugget) Coombs, the Governor of the Reserve Bank of Australia (RBA) at the time, decided to turn to science to address this problem. He believed that scientific advancements could create a greater distinction between the forgeries and the authentic banknote production techniques. In 1968, a 'think tank' was convened in Thredbo, New South Wales, bringing together scientists from the CSIRO and universities to tackle the challenge.
Dave Solomon, a member of the CSIRO, made the significant suggestion of replacing traditional paper with a plastic film. Solomon's group developed a unique laminate that could be printed on using conventional methods, with security features applied afterward. This plastic film was more durable and secure against counterfeiting, and it could also be recycled at the end of its useful life.
The first plastic film note with OVDs (Optically Variable Devices) was the commemorative bicentennial $10 note, released in 1988. This marked the beginning of the transition to polymer currency in Australia, and by 1998, all Australian banknotes were issued in plastic. Australia became the first country in the world to fully adopt polymer banknotes by 1996, with the first polymer series issued between 1992 and 1996.
