A month ago, consecutive days of more than 400 new coronavirus cases would have been almost unbelievable.

Sadly, it's become a reality for Victoria. Melbourne has now been in lockdown for a fortnight, desperately trying to get the numbers to fall.

The lockdown was originally imposed for six weeks, but with four weeks to go and the number of cases remaining stubbornly high, is another month going to be enough?

On today's show:

* Is six weeks going to be enough for Melbourne?

* When do we know if it's safe to reopen again?

* Could the virus be circulating in Queensland? What should people there be doing?

* I'm a garden labourer working in Melbourne. My mask is causing my safety glasses to fog up. How do I stop this happening?

* Should people trim their beard to give masks a more secure fit?

* Some people have told me that surface transfer is not an issue anymore. Could you please outline the current understanding of how coronavirus spreads?
