More than 250,000 workers in Melbourne will be forced to stay home to try and stop the spread of coronavirus.

Yesterday, Victorian Premier Daniel Andrews ordered the closure of thousands of shops, factories and offices in an attempt to not only flatten the curve but force it downwards.

So as the Victorian Government ratchets down restrictions even further, you'd be forgiven for thinking 'what was the point of stage 3?'

So today, why stage 3 lockdowns were successful, but not quite enough.

On today's show:

* What's the point of the new restrictions that are closing businesses across Melbourne?

* Were stage 3 restrictions a failure?

* Other parts of the country are increasing restrictions too. Are they a bit spooked?

* Are children really not that infectious? New research seems to challenge that idea and finds they are actually carrying a lot of virus.

* What's going on with rapid testing? The UK are rolling out tests that give results in 90 minutes. Can we have these in Australia too?
