How the transfer actually works
The bus is free, takes approximately five minutes and comes approximately every ten. Both numbers are approximate by the airport’s own description, and the journey time does not include the wait.
When the window matters
A domestic arrival before 4:00am or after 1:30am lands outside the service. That turns a free five-minute hop into a paid transfer, on an itinerary priced as though the terminals were one building.
What the advisory says about Indonesia
Smartraveller advises exercising a high degree of caution in Indonesia overall. That is one level above normal safety precautions, and it is the overall level for the country.
Why the level is set where it is
The advice names security risks as the basis for the assessment. Reading the current entry before booking rather than after paying is the difference between a decision and a discovery.
Bali sits under the overall level
The overall level covers Bali. Smartraveller raises it only for Highland Papua and Central Papua, where it advises reconsidering travel. Even so, it describes a broad picture and says nothing specific about the street or the resort you are staying in.
What a through fare assumes
A fare with a domestic leg is priced as one journey. It does not price the terminal change, and it does not check whether the complimentary bus is running when your domestic flight lands.
Check the clock, then read the advisory
Confirm the domestic leg lands inside 4:00am to 1:30am, then read the current Indonesia advice before paying. Those two checks matter more here than a small gap between two fares.
