Doesn't matter. If you don't have covid, and nobody comes in, you won't get covid.

But that's not feasible in most countries.

Austrailia and NZ don't rely on a just-in-time cross border economy like the US and Europe. Goods arrive after being on boats which have been off shore for days or weeks.

Compare with the US-Canada "border closure", where thousands of trucks, and their drivers, have crossed each way every day all year.

Canada-US could do what they already do with trains: crew change at the border.

Or even trailer drop-off and pick-up for no-chance-of-personal-contact changes.

They just choose not to.

That's still orders of magnitude more goods crossing a border without a quarentine period than you get from air freight to Aus/NZ

I don’t think the issue is quarantining/isolation of goods, but the people transporting it.

Canadian cross-border truckers arriving back from ??? USA are largely exempt from quarantine requirements upon return.
