A bit off topic but just confirming the current RAT requirement for Princess boarding in Australia - is it still attestation (as in they ask and you confirm you have a neg test) or is it like noted on the website (which I thought was US):
"For guests who opt to use a self-administered Rapid Antigen Test (RAT), a photograph is required which includes ALL of the following: 1) the RAT result; 2) a government-issued photo ID; and 3) a device showing the time (e.g. watch, mobile phone lock screen, clock)."
