My experience in DPS in January. Most banks limit withdrawals to IDR 1,500,000. The at least three exceptions: Citibank, BNI and Maybank which allow ID 3,000,000. Citibank and BNI are located in the international baggage reclaim hall (with about 4-6 other bank's ATMs). Maybank is located in the domestic baggage reclaim hall.
The ATMs advise you of their fees and withdrawal limits before you hit the button.
