Agreed.South Korea has about 9k cases and 120 deaths. We have 8k cases and 422 deaths.
SK aggressive testing regime helped them better understand how the virus spread and subsequently they were better at controlling it, I believe Germany is likewise.
Control the spread you suppress the number of infecred and thus the deaths.
Assuming that our healthcare is comparable and given the ratio in other countries we've probably got closer to 40-50,000 cases, just undiagnosed. Possibly a lot more as there's supposed to be about 2 weeks or more between contracting the disease and dying from it on average. So it may be better to say that we probably had 40-50k cases a fortnight ago.
