According to the Internal Displacement Monitoring Centre (IDMC), more than 60% of the internal displacements recorded worldwide in 2021 were due to disasters. A conservative estimate by IDMC reports 65,000 new displacements between July 2019 and February 2020 as a result of the Black Summer bushfires and more than 42,000 displacements due to flooding in February and March 2022 in Australia. These are estimates as there are no consistent or consolidated data on those who are displaced in Australia affecting the measurement of the magnitude of displacement, and the knowledge of experience, impact and needs of displaced people to inform policy and practice. Thus, the aim of this study, as part of a larger project, is to review key international and Australian policies about data on internal displacement due to disasters.

We conducted a desk review of key international policies, such as the Sendai Framework for Disaster Risk Reduction and from the United Nations Office for the Coordination of Humanitarian Affairs (UNOCHA), as well as Australian policies such as the Australian Disaster Preparedness Framework, Emergency Management Arrangements Handbook and even state level emergency legislation/acts and plans to understand the data collection and supports and services provided to those who become displaced due to disasters.

This review found that both international and Australian policies lacked specific focus on internal displacement, despite it being a key issue. While international policies and procedures in low income countries exist, in particular where the international humanitarian system is operational, this review found that Australia lacked specific focus on internal displacement.

Data on displacement due to disasters, including the number of people displaced, and the patterns of their displacement is critical to inform better policies on prevention, emergency planning, evacuation response and finally to improve the support that people who are experiencing displacement receive.
