The official currency in Bali is the Indonesian Rupiah (IDR) . The Indonesian Rupiah has denominations of 1,000, 2,000, 5,000, 10,000, 20,000, 50,000, and 100,000. It is best to exchange foreign currency for Indonesian Rupiah at authorized money changers to avoid lower rates at airport money changers. Prices in Bali are usually listed in Rupiah, and cash is the preferred method of payment. While some larger hotels and establishments may accept Australian Dollars (AUD), the exchange rate may not be as favorable. It is recommended to check the most up-to-date exchange rate before traveling to Bali.
