The Australian Department of Health implemented the vaccination requirement on June 15 for all international and domestic arrivals to the Northern Territory. Proof of vaccination must be uploaded via the Digital Passenger Declaration at least 72 hours before arrival. Two confirmed cases in May prompted the measure.
The vaccine is free for visitors at Darwin and Alice Springs airports. Children under 12 and pregnant travelers receive medical exemptions with documentation. The requirement applies regardless of length of stay.
Japanese encephalitis has expanded its range in northern Australia due to climate factors. Similar requirements already exist in parts of Indonesia and Thailand. Health authorities project the policy will remain active for at least two years.
Other Australian states are monitoring case numbers before considering parallel rules.
What this means for you
Get vaccinated at least two weeks before travel and upload the certificate to the app. Carry a printed copy as backup. Travelers arriving without proof will be directed to airport vaccination clinics at their own expense.
Check with your doctor about any contraindications, especially for older adults. Book accommodations that include mosquito protection measures.
The requirement is expected to stay in place until case numbers drop significantly.
