Despite the regulations and curfew, the success of the lockdown was largely because of the voluntary behaviour of Victorians. Epidemiology is a discipline mired in complexity, mindful of both numbers and social/economic factors which govern responses to disease control. No one has a better handle on the numbers than University of NSW professor Mary-Louise McLaws, one of Australia and WHO’s most respected epidemiologists. McLaws was adamant that Victoria’s response to the outbreak was correct, and she was very clear about interpreting the numbers.
