What a difference a little bit of time can make.

A month ago today, it was bleak. Melbourne was already several weeks into stage 4 lockdowns and posted more than 200 new cases of coronavirus.

But now it's looking much better. In Melbourne yesterday, the vast majority of cases were connected to aged care outbreaks with only four under investigation.

And states and territories are slowly reopening their borders, allowing us to travel far more freely once again.

So if internal borders are coming down, what can we hopefully look forward to next?

On today's show:

* With all the second waves cropping up globally are we getting more information on how people who had COVID-19 in the first wave are immune to infection the next time around?

* I have had a cough, sore throat, fatigue and breathlessness. I had the COVID-19 test which was negative. What's going on?

And Tegan talks about concerns that COVID-19 could lead to a pandemic of Parkinson's disease in the years ahead.
