Objective(s): Australia requires high quality evidence to optimise likely health and economy outcomes to effectively manage the current resurgence of COVID-19. We hypothesise that the most stringent social distancing (SD) measures (100% of level in Australia in April 2020) deliver better public health and economy outcomes. Design: Fit-for-purpose (individual-based and compartment) models were used to simulate the effects of different SD and detection strategies on Australian COVID-19 infections…

Health and economic costs of early and delayed suppression and the unmitigated spread of COVID-19: The case of Australia
It is found that early rather than delayed mandated suppression imposes much lower economy and health costs and in high-income countries, like Australia, a ‘go early, go hard’ strategy to suppress COVID-19 results in the lowest estimated public health and economy costs.
Deciphering the COVID-19 Health Economic Dilemma (HED): A Scoping Review
This review unveiled the need for information-based decision-support systems which will combine pandemic spread modelling and control, with economic models, and is expected that the current review will not only support policy makers but will also provide researchers on the development of related decision- support-systems with comprehensive information on the various aspects of the HED.
Association of Simulated COVID-19 Policy Responses for Social Restrictions and Lockdowns With Health-Adjusted Life-Years and Costs in Victoria, Australia
The estimated most cost-effective (optimal) policy response was that with the highest NMB, and moderate elimination was optimal from a GDP perspective in half of the simulations, followed by aggressive elimination in a quarter.
Robust estimates of the true (population) infection rate for COVID-19: a backcasting approach
A strong and statistically significant negative relationship between the proportion of the population who test positive and the implied true detection rate is found and, despite an overall improvement in detection rates as the pandemic has progressed, the true number of people to have been infected was 6.2 times greater than the reported number of cases.
Covid heterodoxy in three layers
Lockdowns and related policies of behavioral and economic restriction introduced in response to the COVID-19 pandemic are criticized, drawing on three sets of ideas and arguments that are organized


Health and Economic Costs of Early, Delayed and No Suppression of COVID-19: The Case of Australia
In high-income countries, like Australia, a go early, go hard strategy to suppress COVID 19 results in the lowest estimated public health and economy costs.
Maximizing the probability that the 6-week lock-down in Victoria delivers a COVID-19 free Australia
This study highlights the need to understand more fully the rationale behind the continued use of these methods, as well as the barriers to adoption, to address these barriers.
Victoria’s response to a resurgence of COVID-19 has averted 9,000-37,000 cases in July 2020
Daily diagnosed COVID-19 cases in Victoria are analysed, examining the effectiveness of control measures to date and estimating that control measures have reduced the reproduction ratio from 1.75 to 1.16 and averted 9,000–37,000 infections between 2 and 30 July.
New Zealand's COVID‐19 elimination strategy
New Zealand’s “go early, go hard” approach to elimination in response to the coronavirus disease 2019 pandemic surprised many, but there were compelling reasons for NZ to pursue elimination.
Interpreting the effect of social restrictions on cases of COVID-19 using mobility data
Coupling data for confirmed COVID-19 cases with mobility trends offers insight into the efficacy of restrictions in Australia, Sweden and South Korea and reduces the degree of social restrictions as the pandemic progresses.
