Department of Health Managed quarantine for international arrivals continues to play a vital role in Australia’s public health response to COVID-19. Through the Continuous Improvement Framework, the Australian Health Protection Principal Committee (AHPPC) regularly consider lessons learned in managed quarantine including the outcomes of evaluations, audits and reviews. This supports a process of continuous quality improvement in line with the National Principles for Managed Quarantine (the Principles). AHPPC noted the need for a national understanding of those travellers that return to their place of residence after leaving quarantine, and reinforced advice that all travellers leaving managed quarantine must get tested and isolate until they receive a negative test result if they develop symptoms at any time in the 14 days after leaving quarantine.
