I recently gave a speech to the Australasian Society for Infectious Diseases specialists about our COVID-19 response. Of course, in many ways Australia and New Zealand's responses are very similar, and we reflected on that. One of the key things relates to our testing regimes. Both countries have some of the highest rates of COVID-19 negativity in their tests done in the world. That reflects our similar approach to managing COVID19: trying to drive the number of cases down to zero. What that means is that we are looking for a needle in a haystack, so we have high testing rates and low positivity numbers. And what that means is that we can have high confidence in Australia as a partner for this quarantine-free travel.
