What proof of onward travel is required for Bali e-visa if leaving Indonesia from a different island?

If you plan to exit Indonesia from a different city (e.g., Medan to Penang), you can attach that specific ticket to your e-visa application. Immigration officers understand that tourists island-hop and may depart from a different airport than their entry point.

When applying for a second consecutive e-visa, you can reuse the same onward departure ticket from the first application, as long as the departure date falls within the validity period of the new visa.

A cheap booking confirmation or unticket reservation is generally sufficient for the e-visa application — a fully paid ticket is not required. Border officers at Bali airport typically do not re-check onward travel documents upon arrival.
