I thought this was an interesting article, with regard to how the cluster developed and the timing of the Sydney lockdown:
On Wednesday, NSW Chief Health Officer Kerry Chant said locking Greater Sydney and its surrounding areas down earlier would not have made a difference to the Delta variant's spread, because businesses like Great Ocean Foods would have continued to operate.
"Clearly the issue is that this had established a number of workplace clusters, which then provided seeding. So those workplace clusters would have seeded because essential work would have still continued," she said.
"When you look at the weekend before lockdown was implemented, the case rate was tiny, six cases, with four announced after the deadline," she said.
"To suggest you'd go into lockdown for six cases, even if you knew another four were coming in, you should not have to do that."
Fiona Stanaway, a senior lecturer in epidemiology at the University of Sydney, also thinks the timing of the lockdown was understandable.
"They didn't know about the workplace clusters. If they had known, they could have locked down sooner," she said.
