The first case of coronavirus disease 2019 (COVID-19) in Australia was reported in late January 2020. During the first year of the pandemic, most cases were in Victoria. With the re-opening of interstate borders in late 2020, case numbers rose in other states but remained markedly higher in Victoria. In 2021, the Delta variant of the causative virus, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), became dominant; it was more infectious than the original pandemic strain and caused more severe disease in children.

In Victoria, the October 2021 peak in COVID-19 case numbers was higher than the peaks of March and July of 2020. It was followed in December 2021 by the rise of the Omicron variant, more infectious than previous strains but causing milder illness.
