Will lockdown need to be longer in the age of Delta? - a podcast by ABC News

Sydneysiders are being warned to expect daily case numbers to jump around over the next few days, as the scale of the outbreak becomes clearer.

In other states and territories, the outbreaks are smaller - but it's still too early to know where this might head next.

One thing is for sure: the Delta variant is far more infectious than previous strains - and according to modelling, that means we can expect to see more cases than we otherwise would have.

So on today's Coronacast, when might the outbreaks peak and can we stay ahead of this virus?

Also on today's show:

* NSW Health Minister reveals an interesting story about vaccination and the superspreading birthday party

* You said in a podcast recently that the government should focus on just getting as many first doses out there, but then it was mentioned that a first shot of AstraZeneca or Pfizer isn't that effective and you need that second dose. These statements seem to conflict.
