I'm either misinterpreting totally, or all of the various green list locations essentially have some form of quarantine for age 12 and over, even if it's just while waiting for test results come back (which could be a few days of the holiday). That includes children who are exactly 12 years of age.
That's even when travelling with 2 fully vaccinated adults?
If anybody has seen any destinations where that isn't the case, do please share!
