Yes, still have lots to learn about the Aussie paper notes but it seems very similar.
Here they have pre- and post-decimal notes, there used to be an Australian pound until the 1960s which was equal in value to the UK pound. So there were 10 shilling, 1 pound, etc. notes.
Then in 1966 they switched over to the Australian dollar and there were a whole new set of notes. Then in the early 1990s they switched over to polymer, or plastic, banknotes. Sure you can put them through the washing machine and not ruin them but I do not like the appearance of them compared to paper notes. But then again I think older banknotes are much more beautiful than modern notes.
An interesting thing I have learned is that you can put banknotes into your pension plan! They have something equivalent to CPP here called Superannunation which is paid as a percentage of your salary, but you control where you put your money. So you can deposit your pernsion money into an account which can then be used to purchase rare coins and banknotes, which must be kept in a safe deposit box. Then when you are retired you can sell the notes as required. According to reports Australian banknotes have provided a higher return than any other asset over the past 30 years.
