Currency Australia prior to dollars & cents...?

My wish is to be able to provide equations of our former currency, allowing conversions of all coins & notes, eg;

1; a pound to a dollar
2; a fathom, halfpenny, shilling etc to our current coins
3; a comparison example of an amount eg $750 to pounds.

Finally I seek the names for each of the former coins & notes, as well as their nicknames (zac, dina, quid etc).

Your help is appreciated.

Prior to 1966, Australia used the British system of Pounds/Shillings/Pence.
1 Pound = 20 Shillings
1 Shilling = 12 Pence = 2 Sixpence = 4 Threepence = 24 Halfpennies
1 Florin = 2 Shillings
1 Crown = 5 Shillings

In 1966, 1 Pound became 2 Dollars.
So...1 Dollar equals 10 old Shillings or 5 old Florins or 120 old pence.
