All the many countries (it's not just Australia and New Zealand) who restricted their borders still receive food and medical imports. Genuinely essential travel too. It's managed through real quarantine and proper testing, tracking, and isolating.
Do people really prefer our way? Repeated long lockdowns (with the mental and physical health impacts), over 150,000 dead, more than 1 million long term ill, and so many ruined busineses.
Really?? That's preferable to temporary restricted borders?
Personally I'd rather restricted borders but minimal lives lost, no long covid, and domestic freedom. Open bars, shops, pubs, restaurants, domestic tourism, offices, sporting events. Oh, and fully functioning hospital and doctor care (instead of our years long backlog).
