Accompanying my vaccinated Indonesian girlfriend for a 3 week visit of Indonesia as unvaccinated person

As per the latest Timatic update, Indonesia dropped all Covid restrictions on June 9th 2023, meaning that anyone can enter the country without a vaccination certificate. Masks and all other restrictions have likewise been fully eliminated.

TIMATIC (document database used by airlines) states :

Passengers must have a COVID-19 vaccination certificate showing that they were fully vaccinated at least 14 days before departure. The certificate must be issued in both English and a local language of the country where passengers were vaccinated.

• This does not apply to passengers younger than 18 years.
• This does not apply to passengers with a COVID-19 recovery certificate stating that they are no longer contagious with COVID-19.
• This does not apply to passengers with a letter issued by a doctor proving that the passenger is medically unable to receive the vaccine.

Passengers must download the 'SatuSehat' mobile app before departure.

Passengers and airline crew must complete the “electronic Customs Declaration (eCD)" at https://ecd.beacukai.go.id/ . This will generate a QR code which must be presented upon arrival.

Passengers could be subject to a COVID-19 PCR test upon arrival.

About what counts as being fully vaccinated, the US Embassy in Indonesia state :

Vaccination

Travelers must show a physical or digital vaccination certificate for the second dose of COVID-19 vaccine received not less than 14 days prior to departure. This requirement does not apply to travelers under 18 years old; travelers who have special health conditions or comorbidities preventing vaccination (as demonstrated via letter from a medical doctor); travelers who have finished quarantine or recently recovered from COVID-19 (as demonstrated by a letter of recovery from a hospital or licensed doctor); or those travelers who have not been vaccinated but must travel domestically to depart via an international flight.

The Indonesian Government recognizes the following vaccinations: two-doses Pfizer, Moderna, Sinovac, AstraZeneca, or Sinopharm and single-dose of Johnson & Johnson.

Testing

Upon arrival, travelers will complete a COVID-19 symptom check, and temperature check. If the traveler has no symptoms and normal If the traveler is symptomatic or has a body temperature above 99.5 F, a PCR test will be taken at the airport. If this test is positive, the traveler must isolate at their residence or a facility approved for COVID-19 isolation. The traveler is responsible for all associated costs.

Quarantine

• There is no quarantine requirement for travelers who are fully- vaccinated.
• Quarantine period of 5 x 24 hours is needed for international travelers who have not been vaccinated or have received first dose of vaccination of a two-dose vaccination regime.
• Travelers under 18 years of age will follow the quarantine provisions of their parents/caregivers.
• International travelers are responsible for all expenses during the quarantine, including the COVID-19/PCR tests

I'd make very sure that you'll have enough time to get vaccinated and leave 14 days out before leaving for Indonesia

Are you not vaccinated because of a medical condition or because you simply refuse the vaccination? In the first case, bring a certificate (translated into english) that certifies the reason why you did not get vaccinated.

If you just did not want to get the vaccine: stay at home. Indonesia still requires proof of vaccination. You might be lucky and get in, but you might as well not be. I entered Indonesia twice in November and December and my certificate was checked both times. I also had to show proof of vaccination once when entering an airport before taking a domestic flight. You made a conscious decision not to get vaccinated. Either bear the consequences or get vaccinated.
