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.
I don’t think anyone has said that - it’s a total straw man. I agree that we should have had better border controls, and been better at an awful lot of other stuff too.
But it’s factual that an Australian-style hard border isn’t practicable for a country like the UK that is so heavily dependent on RORO freight for its imports. Even without the question of the Irish border.
Over half of cargo vessels arriving at our ports are RORO vessels. Can you explain how you’d apply the rules for eg maritime workers at the Australian border to a Hungarian lorry driver who has to get from Grimsby to Ludlow, drop off the goods at a warehouse and get back again?
