Im not sure what the message is of all that post but to be correct.
The English currency was used in Australia and some spanish currency as well in the early 1800's and was backed by the Commonwealth, that is the wealth of the English Commonwealth.
Handwritten notes backed by the English treasury were also used. In the early 1800's coins with New South Wales stamped on them were official currency, also backed by the Commonwealth.
Banknotes were issued in N.S.W. in 1817 when they created the bank of N.S.W. These were used until and after 1910 when Australian coins came into being.
In 1913 Australian notes were issued.

Oh and as a note the AUD came into circulation on the 14th Feb 1966 also backed by the Australian wealth of the country.
There is plenty of info around on this if you care to read it.
