"Air Niugini and ISOS continue to offer free PCR and RAT at the airport at time of departure for those who choose to do their test at the airport before check in," Air Niugini said.
"The opening time for the ISOS testing facility is three hours before the originally scheduled departure time for all flights. Even if the departure time is changed, ISOS will still close two hours before originally scheduled departure time, unless you are specifically advised otherwise."
The following requirements are unchanged:
• All passengers traveling to Australia must complete a negative rapid test within 24 hours of scheduled departure.
• All passengers transiting via Australia or Singapore to a third country (other than the UK) must either complete a negative PCR test at the airport, or present a compliant negative Covid test certificate.
