The continued decrease in new cases observed this fortnight in Victoria was the result of the public health interventions to minimise transmission. A total of 8 deaths were reported from cases diagnosed in this reporting period, all of whom were >75 years old, and all from Victoria. Although testing rates declined over the past month, they remain high at 10.4 tests per 1,000 population per week. There is variability in the testing rate by jurisdiction; the rate depends on the epidemic context. The overall positivity rate for the reporting period was 0.08%. Victoria reported a positivity rate of 0.18% for this reporting period, while in all other jurisdictions the positivity rate was 0.05% or lower.
