Australian currency is unique and stands out from other currencies around the world. The notes are made from a synthetic polymer, which has a waxy feel, while the notes of the U.S. and several other countries are made from cotton fibre paper. Australia was the first country to print notes on polymer plastic instead of paper. Polymer banknotes last significantly longer than paper notes, are harder to counterfeit, and are more cost-effective.

What You'll Learn
Australian banknotes are made from polymer plastic, not paper
Polymer banknotes are made from a synthetic polymer such as biaxially oriented polypropylene (BOPP). They are created by melting and stretching polypropylene, blowing it into a bubble, and then squashing it back down to get a film. The unique material has a range of benefits, including increased durability, lower average issue costs, and a reduced environmental impact due to their longer lifespan. Polymer notes are also more hygienic, as they are resistant to moisture and dirt.
The polymer notes include many security features not available in paper banknotes, such as intaglio printing, watermarks, and state-of-the-art metal threads. The use of fluorescent inks and optically variable devices (OVDs) also helps to protect against counterfeiting.
The design and appearance of Australian banknotes are also notable, with each note featuring important Australians and special Australian designs. The notes are also different in size and colour, making it easy to distinguish between denominations by touch.

Polymer notes last longer than paper notes
Australian banknotes are made of polymer, a synthetic material like biaxially oriented polypropylene (BOPP). They were first introduced in 1988, coinciding with Australia's bicentennial year. By 1996, the Australian dollar was switched completely to polymer banknotes, making it one of the first countries to do so.
Polymer banknotes have several advantages over traditional paper notes. One of the most significant benefits is their durability. Polymer notes last significantly longer than paper notes. This increased longevity leads to a reduced need for replacement, lowering the cost of production and distribution. The longer lifespan of polymer notes also contributes to a decreased environmental impact, as they require less frequent replacement, reducing the resources and energy consumed in the production and distribution of new notes.
The durability of polymer notes also helps maintain their cleanliness over time. They are less susceptible to the wear and tear that paper notes experience, resulting in a more aesthetically pleasing appearance even after extended use.
The unique properties of polymer material also make these notes harder to counterfeit. The clear windows, optically variable devices (OVDs), and security features like metameric and fluorescent inks in Australian polymer notes enhance their security. These features create complex optical effects that are challenging for counterfeiters to replicate, thus deterring counterfeiting attempts and increasing the security of the currency.
Polymer notes have gained popularity globally, with countries like the UK, New Zealand, Romania, and many others adopting them. They are often celebrated for their durability, security features, and reduced environmental impact. However, it is important to acknowledge that some countries, like Nigeria, have faced challenges with the processing and destruction of polymer notes, highlighting that a smooth transition requires a comprehensive understanding of the unique characteristics of this material.

Polymer notes are harder to counterfeit
Australian currency is known for its unique character and colourful designs. The country was also one of the first to introduce polymer notes, which are now used in many countries across the world.
Polymer notes also feature a distinctive plastic window with built-in security features, such as an optically variable device (OVD) that creates a rainbow of colours when light hits it. This window can be inspected to verify the authenticity of the note. Additionally, the raised texture of the numbers and portraits on the note can be felt by running your fingers across its surface.
The durability of polymer notes also contributes to their counterfeit resistance. They are far more long-lasting than paper money, lasting up to two and a half times longer. This extended lifespan reduces the need for frequent replacements, making it harder for counterfeiters to circulate fake bills.
While polymer notes are harder to counterfeit, it is important to note that it is not impossible. In 2020, a Romanian man was arrested for possessing high-quality counterfeit polymer notes, demonstrating that counterfeiting technology is constantly evolving. However, the intricate security features of polymer notes remain a strong deterrent against counterfeiting attempts.

Paper notes are used in the US and several other countries
The US and several other countries use paper notes as their form of currency. A banknote, also known as a bank note or bill, is a type of paper money that is issued by a bank of issue and payable to the bearer on demand.
Historically, banknotes were issued by commercial banks, which were legally required to redeem the notes for legal tender, usually gold or silver coins. These days, most national currencies have no backing in precious metals or commodities and have value only by fiat. Coins are typically used for lower-valued monetary units, while banknotes are used for higher values.
The ease with which paper money can be created has led to a temptation in times of crisis, such as war or revolution, or merely a spendthrift government, to produce paper money that is not supported by precious metals or other goods. This has often led to hyperinflation and a loss of faith in the value of paper money.
In recent years, several countries have switched from paper notes to polymer banknotes, which are made from a synthetic polymer such as biaxially oriented polypropylene (BOPP). Polymer banknotes were first issued as currency in Australia in 1988 and by 1996, the Australian dollar was switched completely to polymer banknotes. Other countries that have fully converted to polymer banknotes include New Zealand, Romania, Vietnam, Brunei, Nigeria, Papua New Guinea, the Philippines, Canada, and many others.
Polymer banknotes offer several advantages over paper notes, including increased security features, improved durability, and reduced environmental impact due to their longer lifespan.

Polymer notes are more environmentally friendly
Australian currency has been through several changes since the country switched to dollars in 1966. The new banknotes included several security features designed to deter counterfeiters, such as watermarks, intaglio printing, and metal threads. However, it was in 1988, coinciding with Australia's bicentennial year, that the country first introduced polymer banknotes. By 1996, the Australian dollar was completely switched to polymer banknotes, making it the first country to do so.
Polymer banknotes are made from synthetic polymer substrates (polypropylene), which consist of chains of joined individual molecules or monomers. Polymer is strong, printable, and suitable for enhanced security features. The surface of polymer banknotes is very smooth, making them less susceptible to dirt. They can also withstand extreme temperatures and are relatively easy to clean.
Polymer banknotes are more environmentally friendly than paper notes for several reasons. Firstly, they last significantly longer than paper notes, which often succumb to wear and tear. A study commissioned by the Bank of England found that polymer banknotes last 2.5 times longer than paper banknotes. This means that fewer polymer notes are needed over time, resulting in a decreased need for raw materials and a reduced environmental impact.
Secondly, polymer banknotes are recyclable. The shredded notes can be heated and transformed into recycled polymer pallets, which can then be used to create new plastic items. However, it is important to note that some concerns have been raised regarding the environmental impact of polymer banknotes. For example, a side-by-side comparison of polymer versus paper banknotes found that the new polymer notes released a higher amount of CO2 emissions over their lifetime. Additionally, the production of certain polymers, such as palm oil, is known to be non-environmentally friendly, and the use of animal fat in polymer banknotes has been met with criticism from vegan and religious groups.
