Indonesia’s monetary unit is the RUPIAH (Roo-pee-ah) symbolised as “Rp”. Like Dollars, rupiah are written “Rp 1,000” but said “1,000 Rupiah”. Some tourists refer to “Rupes” when speaking English, but when speaking Indonesian you should only say “Rupiah”. Recently one Australian Dollar was worth just over Rp 10,000. The rate fluctuates daily so only change enough for a few days.
