Regardless of all the opinions of border closures and loss of business, one of the great successes was the contact tracing that was put in place. It allowed the Government to track down anyone who infected others in a public place, like a restaurant. Some of the border closures were over the top, but stopping international flights coming in was great even though the Chinese got their pasties in a wad over that. Even though they stated the who bloody thing. I think that basically being an Island Nation was also a big help, plus our relatively small population; around 25 million in a country roughly the size of the Continental US.
