Just out at Perth airport today dropping a friend off for Bali.
Money Change at the airport was $110 AUD for $70 USD = 2 persons
Recent reports on BTF state that if paying in Aussie Dollars at Bali it's about $49 AUD each. I got $70 USD at a Flight Centre money changer last week for $90.85.
It will always change a bit with the fluctuating currency but close.
By the way Perth airport offering 860,000rp for $100 Aud today. A lot better street Value in Bali.
