You will find that early in the week the Commonwealth Bank ATM's give out Rupiah. However after 12 noon on Wednesdays they give out Australian Dollars.
This is to allow tourists going to Bali to get their rupiah first up. They can then withdraw dollars towards the end of the week for when they go home.
Personally I think that this is a stupid system and I hope they go back to the older system of simply dishing out one currency or the other.
