What happens if you travel to Bali without a visa?

If you're an Australian citizen travelling to Bali for tourism for 30 days or less, you can enter Bali under the Visa Exemption program without obtaining a visa beforehand. However, if you need a visa but arrive without one, you may be able to purchase a Visa on Arrival if eligible. If you don't qualify for either option, you may be denied entry and returned to your departure point at your own expense. 

Any advice is general advice only and does not take into account your individual objectives, financial situation, or needs. As entry and visa requirements for Bali may change over time, it is your responsibility to verify entry and visa requirements with the official government authorities including the Indonesian Directorate General of Immigration, the Indonesian Embassy in Australia, or your local Indonesian Consulate.
