      The Australian 100 dollar note was first issued in 1984 due to inflation. There have been only two different issues of this denomination: initially a greyish blue paper note, and from 1996, a green polymer note. There were 221,842,984 paper notes issued before its withdrawal.

Since the start of issuance there have been six signature combinations. Two other combinations were not issued.

Since 1973, the main title identifying the country on banknotes has been "Australia". The denominations issued prior to 1973 used "Commonwealth of Australia".

     The paper issue has a portrait of Antarctic explorer Douglas Mawson, with a background of a mountain range with a geological strata format. A large diamond shape appears to the left of the main picture. Astronomer John Tebbutt is on the reverse, with a background of the observatory he built and a local church.

The polymer issue of Australian 100 dollar note was designed by Bruce Stewart, and features portraits of soprano Dame Nellie Melba and engineer and First World War general Sir John Monash. This polymer note is occasionally colloquially referred to as a "jolly green giant" due to its colour and size.

According to Reserve Bank of Australia statistics, the number of $100 notes in circulation in June 2015 was 300 million or 22% of all Australian dollar notes in circulation. The cash value for these notes was $29,951,000,000 or 46% of the total value for all denominations. Only the $50 note had more cash value in circulation. This can be explained by the fact that automated teller machines dispense $20 and $50 notes, but not $100 notes.

In 2014/15 around 2943 counterfeit 100 Australian dollar banknotes, with a nominal value of $294,300, were detected in circulation.

Security Features of 100 Australian dollar note

+ A clear window has a stylised image of a lyrebird printed in it, along with embossing of the number '100' (both can be seen from either side of the banknote).
Examine the clear window. Genuine banknotes have a clear window – the area around the window is uniformly smooth to touch. The clear area should be part of the banknote and not an addition. Check the clarity of the clear window.

+ Feel the banknote: A genuine Australian 100 dollar note is printed on polymer (plastic) and has a distinctive feel. Check that the suspect banknote is not excessively thick or thin compared to a genuine banknote.

+ When the note is held to the light, a seven pointed star within a circle is formed by four points on one side of the banknote combining perfectly with three points on the other side.

+ When the note is held to the light also, an image of the Australian Coat of Arms can be seen under other printing.

+ The words ‘ONE HUNDRED DOLLARS’ and the number ‘100’ are microprinted and can be seen with the aid of a magnifying glass.

+ Slightly raised printing that can be felt with the fingers is used for the portraits and other major design elements.

+ Intricate multi-coloured fine-line patterns and images appear on each side.

+ Each Australian 100 dollar note's serial number is printed twice, one in brown and one in green, on the back of the banknote. A different font is used for each serial number. The alpha prefix of two letters is followed by two numerals representing the year of the production, followed by a further six numerals. Under ultra-violet light, the serial numbers fluoresce.

+ Under ultraviolet light a patch showing the number '100' becomes visible on the back of the 100 Australian dollar note.
