Department of Health Managed quarantine for international arrivals to Australia – including hotel quarantine and other highly controlled settings – is Australia’s first line of defence against COVID-19. It continues to play a vital role in Australia’s public health response. The Australian Health Protection Principal Committee (AHPPC) is committed to continuously improving managed quarantine arrangements, in line with the AHPPC Framework for Continuous Improvement. This includes considering and implementing the recommendations of previous reviews into managed quarantine. The National Principles for Managed Quarantine provide nationally agreed guiding principles to set benchmarks for managed quarantine programs across Australia. The Principles seek to protect the health and wellbeing of the Australian community, quarantined individuals and workers involved with quarantine.
