The value changes daily. The Aud goes up against the USA$ and so does the IDR.
If you are going to buy at a currency exchange in Aust you pay a commission so you have to take that into consideration.
Watch the value of the dollar and when it gets over 90 exchange some so when it drops and you go overseas you are better off.
100 AUD today would get you $84,883 american
That $84.883american would get you 770,313 IDR
100 AUD today would get you 770,427 IDR
So you are better off with Australian dollars TODAY
What can you get for 120 IDR
Hope this makes sense. There is not much difference
