Timor-Leste remains in a state of transition. The country faces continuing challenges that limit its law enforcement capability. Many civil and governmental institutions are still being developed with international assistance. If you are traveling or doing business in Timor-Leste you may find it difficult to identify legal or administrative mechanisms if problems arise.
The U.S. dollar is the official currency of Timor-Leste. You can exchange money at the three banks in Dili, but only to or from the Indonesian Rupiah, Euro, British Pound, Australian Dollar, Singapore Dollar, and Japanese Yen. Only a few establishments accept credit cards, usually requiring a substantial additional fee, and you should be prepared to settle all bills in cash. Dili has several ATM machines that accept U.S.-issued bankcards. However, you should not plan to rely exclusively on these machines, as they are frequently inoperative.
If you intend to travel to Australia from Timor-Leste, you should be aware that the Australian immigration authorities require an Electronic Travel Authorization (ETA) in advance of arrival.
