What You'll Learn
The history of Australian banknotes
In 1817, Governor Macquarie established the Bank of New South Wales, which issued Pre-Federation notes. The discovery of gold in 1851 also led to the development of banking, with commercial banks issuing their own notes backed by gold. However, people were often wary of these notes, especially after many banks failed in 1893. The passing of the Australian Notes Act in 1910 made it an offence for any bank other than the Commonwealth Treasury to circulate banknotes, and the Bank Notes Tax Act of the same year further discouraged private banknote issuance.
The first Australian banknote was printed in 1913, a ten-shilling denomination, and there have been seven complete series issued since. In 1924, responsibility for issuing banknotes passed to the Board of Directors of the Commonwealth Bank of Australia. The Commonwealth Bank Act of 1945 formally established the Commonwealth Bank as the sole legal issuer of Australian banknotes, and in 1960, this role passed to the Reserve Bank of Australia.
Australia changed to decimal currency on 14 February 1966, replacing the pound with the dollar, and issuing its first decimal series of banknotes. The $1 and $2 notes were replaced by coins in 1984 and 1988, respectively, and all paper notes were replaced by polymer (plastic) notes, with the first polymer series issued between 1992 and 1996. The final chapter in Australia's banknote history came in May 1996 when the $100 note was replaced, making Australia a pioneer in polymer banknote production.

The design process
The 'banknotisation' design stage involves integrating all the features into the banknote to make it functional, secure, and durable. This includes the application of specialised security features to prevent counterfeiting. For example, Australian banknotes are made from a unique polypropylene polymer substrate that is not commercially available. This polymer substrate contains several film layers created using a "bubble" process. Clear plastic beads are melted and blown into a large bubble, during which the film is stretched in both length and width to orientate the polymer molecules.
After the bubble process, strong colours are applied to both sides of the banknote using detailed printing techniques. This includes microprinting, which serves as an additional security feature. Within the top-to-bottom window, various security features are integrated, such as foils that reflect light at different wavelengths depending on the viewing angle. This involves a complicated process of transferring the foil with heat and pressure, similar to ironing it on.
Next, a thick layer of coloured ink is applied using a rolling colour effect technique. This technique involves structuring the pigments within the ink using a series of magnets while it is still wet. The pigments are then locked in place with a UV lamp to create the desired rolling colour effect. Following this, intaglio printing is applied to both sides of the note, giving it texture and body. Intaglio printing involves deeply engraving metal plates with a design and transferring the ink from the plates to the sheets of polymer film under pressure, resulting in a raised print. Finally, a protective coating is applied to the banknote sheets to keep them clean and prolong their lifespan.

Security features
The Australian government has implemented a range of security features to protect its banknotes and make them difficult to forge. Firstly, Australian notes are made from a unique polypropylene polymer substrate, which is not commercially available and requires specialised technology to produce. This polymer substrate consists of several film layers created using a "bubble" process, where clear plastic beads are melted and blown into a large bubble, stretching the film in both length and width to orient the polymer molecules.
Secondly, Australian banknotes incorporate optically variable devices (OVDs) and optically variable inks (OVIs). OVDs are diffractive optical elements that create dynamic, colour-shifting images when viewed from different angles. OVIs, on the other hand, contain pigments that reflect different wavelengths of white light depending on the angle of light incidence, producing a "rolling colour" effect. This effect is achieved by applying a series of magnets to the wet ink and locking it in place with a UV lamp.
Thirdly, intaglio printing is used to give the notes texture and make them easily recognisable by touch. This traditional process involves engraving designs onto metal plates, applying ink to these plates, and then transferring the ink under pressure to the sheets of polymer film, resulting in slightly raised printing.
Additionally, Australian notes feature microprinting, which consists of very fine detailed print that contributes to the security of the currency. The notes also have a protective coating, which helps keep them clean and prolongs their lifespan.
Finally, as of 2015, new Australian notes have included a tactile feature to assist the visually impaired in identifying the value of the note. This feature was introduced after a successful campaign led by 15-year-old Connor McLeod, who is blind.

Printing and ink techniques
The creation of an Australian banknote begins with a large roll of clear polymer film. Special inks are then applied to make the film opaque and help the next layer of ink stick. The banknote sheets are then given a protective coating, which helps keep them clean and last longer.
The next step is to apply strong colours on both sides of the note. This is done through fine detailed printing, which gives the notes bold, vivid colours and built-in security in the form of microprinting.
A top-to-bottom window is then integrated into the note, which involves transferring foil with heat and pressure, similar to ironing it on. A thick layer of coloured ink is then applied, creating a rolling colour effect. This is achieved by structuring the way the pigments sit within the ink. A series of magnets are applied to the ink while it's still wet, and the magnetic fields rotate the pigments within the ink. The design is then locked in place with a UV lamp.
The final step is intaglio printing, which gives the note texture and body. Metal plates are engraved with a design, and ink is applied to the plates. The ink is then transferred to the sheets of polymer film under pressure, leaving a raised print.

Cutting and packaging
Once the design and security features have been integrated into the banknote, it is ready for cutting and packaging. The banknote sheets are given a protective coating to help keep them clean and ensure they last longer. The sheets are then cut into individual banknotes. Each note is checked for errors, stacked, wrapped, and packed onto pallets. These pallets contain millions of dollars' worth of banknotes, which are used to replace worn or damaged notes that are taken out of circulation.
The process of creating the polymer substrate used for Australian banknotes involves a unique "bubble" process. Clear plastic beads are melted down and blown into a large bubble. During this process, the film is stretched in both length and width to orientate the polymer molecules. This creates a substrate with several film layers, which makes it extremely difficult to forge.
The banknote sheets are printed with strong colours on both sides, using a very fine detailed print. This gives the notes bold, vivid colours and built-in security features. One of these security features is a top-to-bottom window, which contains a number of anti-counterfeiting measures. For example, the window may include a foil that reflects light at different wavelengths, depending on the angle at which it is viewed. This creates a "rolling colour" effect.
To achieve this effect, a series of magnets is applied to the ink while it is still wet. The magnetic fields rotate the pigments within the ink, and the design is locked in place with a UV lamp. This rolling colour effect is just one of the many security features that make Australian banknotes difficult to forge. Overall, the cutting and packaging process for Australian money notes is a highly secure and intricate procedure, ensuring the integrity and longevity of the currency.

Australian money notes are made of a unique polypropylene polymer substrate. This plastic film is created by melting clear plastic beads and blowing them into a large bubble, which is then squashed back down into a film.
Australian money notes have several security features, including intaglio printing, which gives the notes a raised texture. They also have optically variable devices (OVDs), microprinting, and a transparent window with a diffractive optically variable device (DOVD) image. The polymer substrate itself is also a security feature, as it is not commercially available and requires specialised technology to produce.
Australian money notes have undergone several changes since the country transitioned from pounds, shillings, and pence to the decimal system of dollars and cents. The notes have featured different individuals, with a focus on depicting more women than men, and have included tactile features to assist the visually impaired. The $1 and $2 notes were replaced by coins in 1984 and 1988, respectively.
Collectors and investors seek rare and historical Australian banknotes, with some of the most valuable notes being those from the first series issued, error notes, and specimen notes. Notes with low serial numbers, star replacement notes, and those printed in the first year of issue are also highly sought-after. The 1966 Coombs/Wilson $20 note is particularly valuable due to its rarity and historical significance.
