Similar data was previously released in Regional internal migration estimates, provisional which covered the period June 2020 to March 2021. Internal migration for GCCSAs by financial year is released in Regional population annually, as regional internal migration estimates (RIME). The internal migration data in RIME and the state and territory migration data presented elsewhere in National, state and territory population are used to compile the official measure of population in Australia. The quarterly internal migration data released in datacube 4 are provisional, and should only be used to provide more timely insights on internal migration patterns.
