The COVID-19 pandemic slowed down international migration around the world, with many countries closing their international borders for a prolonged period of time. Although there are studies emerging that analyse the impact of COVID-19 and border control measures, more detailed migration flow data have been largely absent. In this research note, we examine changes to the patterns of immigration and emigration in Australia during the pandemic to further our understanding of the differing impacts of the pandemic on population groups. Foreign-born populations with large shares of international students recorded the highest declines in immigration, especially those from China, Malaysia, and South America. Immigration of seasonal workers from the Pacific Islands, on the other hand, exhibited increased levels. There were also unexpected situations where residents who made temporary visits outside Australia were unable to return, or persons who were visiting on short-term visas prolonged their stay. Results reveal how responsive migration can be to policies in a time of a population health crisis. The nuance and complexity of these patterns underscore the importance of migration dynamics, adding to our knowledge of the changing international migration profiles during the recent pandemic.
