New Zealand moved to its own Stage 4 with less than 100 daily cases. Should Victoria have acted sooner?

The adoption of tough Stage 4 coronavirus restrictions in Melbourne has prompted questions about whether the Victorian government should have acted earlier. Melbourne was put under a Stage 4 lockdown on Sunday after recording 671 new infections. The rest of Victoria is set to re-enter Stage 3 restrictions at 11:59 on Wednesday. Some, such as physician and broadcaster Dr Norman Swan, have compared Melbourne's situation with New Zealand, which went into its own version of a Stage 4 lockdown before daily cases reached 100.
