The ACT is in a week-long lockdown, joining many other regional NSW local government areas and Melbourne on their journey to stopping Delta.

The ACT Chief Health Officer Dr Kerryn Coleman says as yet there's no known link back to known Sydney cases, and genomic information will be available today.

And Victoria yesterday recorded two cases in hotel quarantine who had arrived on a plane from Sydney.

So on today's Coronacast, with the virus continuing to push outwards, can anything be done to stop it?

Coronacast is taking a small break. We'll be back on Wednesday 18th August!
