The Aussie experience, I asked DFAT for a certificate of entry for December and was told that they do not exist.
Entry is granted to ALL confirmed air tickets?
I suspect it is the responsibility of the airline to ensure that the passengers are eligible for entry and if the flight is granted permission to fly then the authorities have pre booked the hotel accommodation.
I will let you know how I get on, Bacolod to Manila, Manila to Denpasar and Denpasar to Perth, booked paid for and confirmed.
I was hoping that with a negative PCR test before flying and two vaccine shots home quarantine may be allowed but a recent outbreak of the Delta varient has them all in a tizz, so I will probably have to pony up the $2,500 AUD for hotel quarantine.
