we’re going to test 10 million people a week” and then the next “we’ve run out”
The real answer oz is that the government and SAGE have prepared, and have massively upscaled testing capabilities, but two facts have remain. The second spike started in August, which was much earlier than anticipated, they expected at least to get to the end of September. This has not happened, and the same issues around testing and early spikes can be seen all over Europe, not just the UK. The French of course have gone on strike in testing centres, because they are swamped. I am not sure that will help the backlog, the picture is the same everywhere.
Secondly people here are being tested for non covid related symptoms. A sniffle in some cases, and others employers are expecting negative tests in order for some workers to return. So the colossal demand on testing services is not entirely down to bad planning at all, but the perfect storm of many factors.
Are you still unable to travel state to state in Australia? That sounds like a lockdown of sorts as well, when will that be lifted?
