The average rate last week was approx 6900/AUD. Anyone offering you 100 Rp on top of the avg rate is sus. There are only a few money changers who will not clip you for a hudred thou to few thousand rupiah. Deal only with those who deal out no less than 50,000 Rp notes. Anyone who deals out 20,000 Rp notes in bulk is up to no good. Trust me on this as I have tested most of them and only a handful were honest. The Kodak shops are good, the MC outside & next to Matahari is good; last MC in PoppiesI on beach side is good; MC at the end of the lane at Adhi Dharma hotel is good. Count your money last and don't take your eye off the guy dealing the cash. They are very, very good at what they do.
