What You'll Learn
The first plastic banknote
Australia was the first country to issue plastic banknotes, which were introduced in 1988 to coincide with the country's bicentennial year. The first plastic banknote was a commemorative $10 note, which was also the denomination that had been most affected by counterfeiting.
The development of polymer banknotes in Australia was a response to increasing counterfeiting, which had particularly affected the $10 note. In 1967, a group of forgers, including Francis Papworth and Jeffrey Mutton, were found guilty, but the news of the forgeries had already spread and a general distrust of $10 notes permeated Australian society. By the end of 1966, a team of amateurs from Melbourne had produced a batch of fake notes that would net them almost A$800,000 worth of forgeries.
In 1968, the Reserve Bank of Australia (RBA) arranged a 'think tank' of scientists from the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and universities to come together and discuss the challenge. It was during these first few years that Dr David Solomon, a young, award-winning polymer scientist from CSIRO, first hit on the idea of a plastic banknote after being given a plastic business card by a visitor from Japan. By February 1972, CSIRO and the RBA had agreed to commence a project to develop polymer banknotes with a range of optically variable security devices (OVDs).
The new notes were more durable, more environmentally friendly, and less likely to carry dirt and disease. They also had many security features not available in paper banknotes, including the use of metameric inks. Polymer banknotes last significantly longer than paper notes, reducing the environmental impact and the cost of production and replacement.

Counterfeit-proof currency
Australia's banknotes were first switched to plastic in 1988, coinciding with the country's bicentennial year. By 1996, the Australian dollar was fully converted to polymer banknotes. The move to polymer banknotes was initiated by the Reserve Bank of Australia (RBA) to enhance security and make the currency harder to counterfeit.
The development of polymer banknotes in Australia was driven by the need to combat counterfeiting, which had become an increasing concern as modern reprographic equipment became more accessible. The RBA recognised that scientific solutions were required to stay ahead of forgers, and this led to the creation of polymer banknotes with unique security features.
Polymer banknotes are made from a synthetic polymer substrate, specifically biaxially oriented polypropylene (BOPP). This material is created through a specialised process that involves melting and blowing transparent plastic beads into a sizable bubble, stretching the film in multiple directions, and then pinning and cooling the walls to create a transparent polymer film. This process results in a durable and secure substrate that is challenging to replicate.
The use of BOPP in polymer banknotes provides a range of security features not available in traditional paper currency. These notes incorporate intricate images, optically variable devices (OVDs), see-through panels, holograms, and metameric inks. The complexity of these features makes polymer banknotes significantly more difficult to counterfeit compared to paper notes.
The introduction of polymer banknotes in Australia had a significant impact on counterfeiting attempts. Countries that have adopted polymer currency have reported a noticeable decrease in counterfeiting activities. The durability and security features of polymer banknotes make them highly effective in deterring counterfeiting.
However, it is important to recognise that no currency is entirely immune to forgery. Technological advancements used by counterfeiters can sometimes keep pace with security improvements. For example, counterfeiters have been known to replicate colour-changing ink and copy intricate images using high-quality printers and scanners. While polymer banknotes are more secure than their paper counterparts, ongoing innovation is necessary to stay ahead of counterfeiting attempts.

Cost-effectiveness
Australia was the first country to introduce polymer banknotes in 1988, coinciding with its bicentennial year. The commemorative bicentennial $10 note was the world's first plastic film note with optically variable devices (OVDs). The Reserve Bank of Australia (RBA) developed these modern polymer banknotes to make the currency more secure against counterfeiting, which had been on the rise as modern reprographic equipment became more readily available.
Polymer banknotes are made from synthetic polymers such as biaxially oriented polypropylene (BOPP). They are more durable, lasting two to three times longer than paper notes, and require less processing, making them more cost-effective in the long term. The extended lifespan of polymer notes means fewer resources are needed for production and replacement, reducing the environmental impact and cost of replacement. Additionally, old polymer notes can be recycled into plastic products, further reducing environmental waste.
The complex manufacturing process and advanced security features of polymer notes, such as transparent windows, holograms, and raised printing, contribute to higher upfront costs, making them more expensive to produce initially compared to paper notes. However, the durability and longevity of polymer notes result in lower overall costs over time, with fewer replacements needed. The switch to polymer banknotes in Australia has resulted in net savings of close to $1 billion over 25 years, not including the benefits of reduced counterfeiting.
The longer life of polymer banknotes has also led to a series of decisions to outsource the majority of cash distribution to the private sector. This coincided with broader Australian Government competitive neutrality reforms, ensuring that publicly owned businesses did not have an unfair advantage over the private sector. The increased lifespan of polymer notes has also contributed to greater hoarding and less transactional use of banknotes, further reducing replacement costs.
Overall, the switch to polymer banknotes in Australia has proven to be cost-effective, with the combination of long-term durability, enhanced security features, and reduced environmental impact resulting in significant financial savings for the country.

Environmental impact
Modern polymer banknotes were first introduced in Australia in 1988, coinciding with the country's bicentennial year. By 1996, the Australian dollar was switched completely to polymer banknotes, making Australia the first country in the world to do so.
Polymer banknotes have a significantly lower environmental impact than their paper counterparts. Polymer notes last more than twice as long as paper notes, which means fewer notes need to be manufactured and distributed over the life of a series. Polymer notes are also lighter, making their transportation and distribution more energy-efficient. At the end of their useful life, polymer notes can be recycled into plastic pellets and used to make everyday plastic items, such as lawn furniture. On the other hand, paper bills are typically shredded and sent to landfills, contributing to waste accumulation.
A life-cycle assessment of the environmental impact of polymer notes compared to paper notes found that polymer bills offer a 32% reduction in global warming potential and a 30% reduction in primary energy demand. This assessment considered the entire life cycle of the notes, from the production stage to the destruction and disposal of worn notes.
The switch to polymer notes in Australia aligns with global efforts to reduce environmental impacts, particularly in the context of the Paris Agreement on climate change. Polymer notes not only reduce the carbon footprint associated with currency production and distribution but also provide enhanced security features and longevity.
However, it is important to note that Australia has one of the highest per-person consumption rates of single-use plastic in the world, with a significant amount ending up in the environment and threatening marine wildlife. While the recyclability of polymer notes is a positive step, addressing the broader issue of plastic consumption and waste management remains crucial for Australia.

Australia's influence on world currency
Australia's currency, the Australian dollar (AUD), has had a significant influence on world currency in several ways. Firstly, it is a reserve currency and one of the most traded currencies globally, ranking fifth in 2016 and accounting for 6.9% of the world's daily share. This popularity among currency traders can be attributed to factors such as Australia's comparatively high-interest rates, the relative freedom of its foreign exchange market from government intervention, and the general stability of its economy and political system. The AUD is also uniquely tied to the Japanese yen, making it an important currency for FX traders.
The Australian dollar has influenced the composition of currency in other countries. Modern polymer banknotes, first introduced in Australia in 1988, have been adopted by several other nations due to their durability, security features, and environmental benefits. This innovation addressed the issue of counterfeiting and has been exported to over 25 countries, including the United Kingdom, Romania, and Nigeria.
Additionally, the Australian dollar has had an impact on the economies of smaller Pacific Island states. It is the official currency and legal tender in three independent sovereign Pacific Island states: Kiribati, Nauru, and Tuvalu. This influence extends to the pricing of goods and services in these countries, as a depreciation of the Australian dollar would make their exports more expensive for international buyers.
Australia's history and economic standing also play a role in its currency's influence. The discovery of gold in 1851 led to the minting of gold coins and the development of banking in the country. Despite being only the 12th largest country in terms of GDP and 56th in population, Australia's dollar has gained prominence in the global currency market due to its strong trade relationships and commodity exports.
