As a PR, I can go on a holiday in Europe or the US if I want to, but need to face 3 weeks quarantine on return (or what I'd more likely do, is go from Europe or US to Australia first - do 2 weeks quarantine there , then at least another week in Australia, before returning). We contemplated doing this, but our priority for overseas travel is not holidays - but first and foremost seeing family (mothers, siblings, nieces/nephews) and secondarily, maintaining our property back in Australia, and whilst in theory we could do SG->Europe->Australia would not want to jeopardise seeing family for the sake of a couple of weeks in Europe (given the uncertainty around securing seats).
