Executive Summary

In the first quarter of 2023, Australia witnessed a significant growth in its Estimated Resident Population (ERP), increasing by 0.7% compared to the previous quarter, and 2.2% year-on-year. This report delineates the critical factors influencing this growth, including migration patterns and natural increase rates, and offers a detailed breakdown of population trends across different states and territories.

Detailed Analysis

Migration Trends

Australia recorded a historic net inflow of 454,000 migrants in the year leading up to March 2023, with 152,000 arriving in the last quarter alone. This surge was facilitated by a robust increase in arrivals coupled with a decline in departures, contributing 0.6 percentage points to the quarterly population growth.

Natural Increase

The natural increase, calculated as births minus deaths, experienced a downturn, falling to 109,000 — an 18.5% decrease from the previous year. This decline is attributed to a 7.9% rise in deaths and a 3.4% reduction in births over the same period.

State and Territory Breakdown
  • Western Australia: Leading with the fastest population growth at 2.8%.
  • Victoria: Following closely with a 2.4% increase.
  • Queensland: Exhibited a growth rate of 2.3%.
  • Tasmania and Northern Territory: Registered the slowest growth, with rates of 0.4% and 0.9% respectively.
Interstate Movements

Interstate relocations diminished compared to the previous year, standing 19.3% lower than the same period in 2019. Despite a decrease in the last quarter, net moves to regional areas remained above pre-pandemic levels.


Australia’s population dynamics in the first quarter of 2023 were significantly influenced by unprecedented migration rates and changing natural increase patterns. Western Australia emerged as the region with the highest growth, while interstate movements showcased a preference for regional areas. Policymakers and stakeholders must leverage this data to foster sustainable growth and development across the nation.
