Do you need a new Indonesia visa to re-enter Bali after a short trip to Singapore, and can you use Singapore’s 96-hour transit facility?

If you fly onward to a third country after Singapore rather than returning directly to Bali, the visa-free transit facility of up to 96 hours can be used; the discussion confirms a three-day stay in Singapore. The airline will check the onward ticket at check-in.

If you don't have a Singapore visa, add an extra stop in another country (e.g. Kuala Lumpur or Bangkok) on the return leg: a Denpasar–Singapore–Kuala Lumpur–Denpasar routing is suggested as an optimal workaround.

Once you fly from Bali to Singapore, your current Indonesia entry ends. When you return to Bali, it counts as a new entry, so you need to get a new Visa on Arrival or e-VOA.

Even if your whole trip is exactly 30 days, a Bali–Singapore–Bali side trip is not treated as one continuous stay. The first Indonesia entry ends when you depart, and returning to Bali starts a fresh 30-day stay with a new visa payment.

For a Bali–Singapore–Bali routing, Singapore’s 96-hour visa-free transit normally does not work: the discussion notes that you need a regular Singapore visa if your passport is from a visa-required country.
