Prior to the introduction of polymer note technology, Australian banknotes were made from a specially prepared and manufactured paper. Most organisations with the responsibility of manufacturing the nation's currency are reluctant to give any specific details.
Someone can find some Australian notes in Australia as they are used as banknotes there. Information and pictures of Australian Banknotes can be found online on a site called "AustralianBanknotes".
All Australian banknotes will have "AUSTRALIA" printed on them in large, difficult to miss letters. All Australian banknotes have the signatures of the "Governor of the Reserve Bank of Australia" and the "Secretary to the Treasury". All Australian banknotes have a serial number on them in at least one place. All Australian banknotes have "This Australian note is legal tender throughout Australia and its territories", or something similar printed on them. All Australian banknotes have the denomination printed in letters and printed in numerals. All current Australian banknotes are made from a polymer compound and feature various security devices such as holograms and micro printing to make life more difficult for counterfeiters. See the related link below to the Reserve Bank of Australia for more detail on Australian banknotes.
We are not due for a new design of banknotes for a long time yet. Deciding who will appear on Australian banknotes is determined by the Reserve Bank of Australia assisted by a panel of consultants and will also include input from the public. Whatever new faces appear on the next issue of Australian banknotes, they will be historically famous and significant Australians who have made a contribution to the country.
All Australian coins feature the reigning Monarch on the obverse, currently Queen Elizabeth II since 1953. For the introduction of the Australian decimal currency in 1966, it was decided to have a uniquely Australian design for coins and most banknotes. See the links below to the Royal Australian Mint (RAM) and The Reserve Bank of Australia (RBA) for images of current Australian coins and banknotes.

Australian banknotes are all made of plastic, specifically polymer. Australia was the first country in the world to have all its banknotes made of polymer. The composition of the 5, 10, 20 and 50 cent coins is 25% nickel and 75% copper. The $1 and $2 coins are composed of 92 % copper, 6 % aluminum and 2 % nickel.
There are no Australian One Million Dollar banknotes. There are no collectible Australian banknotes that would get anything near One Million Dollars.
At the time of answering - $1.00 USD (US Dollar) = $0.96 AUD (Australian Dollar) or $1.00 AUD = $1.04 USD. There are differences in the banknotes as well. US banknotes are made of paper, whereas Australian banknotes are made of a more durable polypropylene polymer. US dollars come in $1, $5, $10, $20, $50, and $100 notes. Australian dollars come in $2 (although no longer printed, still legal tender), $5, $10, $20, $50, and $100 notes.
All Australian banknotes are made in different sizes and colours to give a clear visual distinction between the different denominations. The historical trend for banknotes (not coins) is that the larger the denomination of the banknote, the larger the banknote.
Australia puts famous or historically significant Australian identities on its banknotes, people who have contributed and made a difference. Apart from the reigning king or queen, all those people who have appeared on Australian banknotes to date are dead, which is one of the current criteria. A few names to consider might be Dr Fred Hollows, Sir Edward "Weary" Dunlop, Peter Lalor, Sir Thomas Blamey, Bert Hinkler, Robert O'Hara Burke and Edward Eyre.
Australia's banknotes are printed by "Note Printing Australia", a wholly owned subsidiary of the Reserve Bank of Australia. The polymer substrate that the notes are printed on is supplied by Innovia Security. Both plants are located at Craigieburn in the northern outskirts of Melbourne.
The 1 million Australian dollar does not exist and cannot be used as medium of exchange. The highest denomination in banknotes for Australia is the $100 note which was released in 1984.
