For passengers who have been vaccinated in PNG, they must produce the yellow International Vaccination Certificate (which is issued by PNG National Department of Health).
The green domestic vaccination certificate is not sufficient. For passengers who were vaccinated overseas, this will be the vaccination certificate issued in the country they were vaccinated in.
There are some exceptions, such as medical conditions.
"All passengers departing internationally will still need to complete a negative PCR test at Port Moresby's Jacksons Airport at time of check-in. Access to testing closes two hours before scheduled departure.
"Wearing of face masks in the terminals and on board the aircraft is mandatory, hand sanitisers are provided for your protection, and social distancing is followed wherever practical in order to ensure your international travel remains as safe as possible."
For incoming international travellers, no person is permitted entry unless they are fully vaccinated unless they are a PNG citizen or permanent resident, or be under the age of 18. If they are unvaccinated (and a PNG citizen/permanent resident, or under the age of 18) they will be required to quarantine for 14 days on arrival.
Fully vaccinated arrivals other than from high-risk destination countries do not require quarantine on arrival, but will be rapid tested at the airport after landing. Additionally, all arriving passengers must show evidence of having completed a negative PCR test within 72 hours of the scheduled departure time of the first leg of your flight to Port Moresby.
"Passengers arriving from highrisk destination countries (presently India and the Philippines) will be required to quarantine for 14 days on arrival. PNG Pandemic Controller approval is also still required before travel."
