The Regional Australia Institute (RAI) in association with the Commonwealth Bank created an analysis of population movement between Australia's Capital Cities and Regions, powered by analysis of proprietary data to create an up-to-date picture of a large sample of relocations. Data spans National as well as Greater Capital City Statistical Area (GCCSA) and Local Government Areas (LGA). Updated quarterly, data ranges from 2018 to 2022. Each report is downloadable as a PDF document. The index is in partnership with the Commonwealth Bank.
