Travel essentials for Indonesia

Adapters, plugs, tap water, tipping and health basics.

Power & adapters

Type C, F adapter required

Indonesia uses the two-round-pin European plug. Australian Type I plugs do not fit — you need a Type C adapter. Voltage is the same as Australia, so no converter is required.

230V, 50Hz

Tap water

Not safe to drink

Do not drink the tap water anywhere in Indonesia, including for brushing teeth in budget accommodation. Use bottled or filtered water and be wary of ice in small warungs.

Staying connected

Good 4G across Bali, Jakarta and tourist areas; patchy in the Gili Islands, Nusa Penida and remote Lombok.

Indonesian eSIMs are very cheap — often under AUD $10 for 10GB. Telkomsel has the best rural coverage.

Tipping and everyday costs

Not traditionally expected but increasingly common in tourism. Many restaurants add a 5 – 10% service charge plus 10 – 11% government tax. Rp 20,000 – 50,000 is a generous tip for a driver or guide.

Indonesia travel essentials FAQs

What power adapter do I need for Bali?

A Type C adapter — the two round pins used across Europe and Indonesia. The voltage is 230V, the same as Australia, so you don't need a voltage converter.

Can you drink the tap water in Bali?

No. Stick to bottled or filtered water, including for brushing your teeth outside good hotels, and be careful with ice at small warungs.
