Six Quarters of Shrinking Slices Expose Australia's Per-Capita Recession

Headline GDP never shrank during the record migration surge, but ABS National Accounts show real GDP per capita fell for six consecutive quarters from June 2023, dropping A$363 per person by September 2024.¹

Correction, 4 October 2026: the Canadian Parliamentary Budget Officer report cited is titled 'Impact assessment of 2025-2027 Immigration Level Plan'; an earlier version gave it a different title. Correction, 4 October 2026: an earlier version said real GDP per capita dropped A$291 per person over the six quarters of falls and called June 2023 a peak. A$291 was measured from the June 2023 reading, after the first fall. Measured from March 2023, before the run began, the drop was A$363 (A$25,052 to A$24,689). The finding is unchanged. Correction, 3 October 2026: chart titles and a few statements now describe only what the data show over the period shown (for example, where one measure rose while another fell, both now hold over the same period). The findings are unchanged. Correction: an earlier version of this article said GDP rose in every quarter and GDP per capita fell seven quarters in a row. ABS national accounts show GDP was flat in the December 2023 quarter, and GDP per capita fell for six consecutive quarters, from June 2023 to September 2024. The article has been updated with the latest data and every figure re-checked.

Australia's economy did not shrink in any quarter of the record migration surge of 2023 and 2024.⁶ Output per person did, for six quarters in a row.¹

ABS National Accounts confirm real GDP per capita fell for six consecutive quarters from June 2023 to September 2024, dropping from A$25,052 in March 2023 to A$24,689 per person in constant 2022-23 dollars, a decline of A$363 per resident.¹ The economy was not shrinking; each person's share of it was, and the ABS published those numbers the entire time.¹

The March 2023 quarter was flat at zero per cent, so the run of falls begins in the June quarter.¹ Aggregate GDP in the December 2023 quarter was also 0.0 per cent, not positive, making that the only quarter in the six-quarter window where both measures were simultaneously flat or negative.⁶

The falls ran from June 2023 (minus 0.3 per cent) through September 2024 (minus 0.1 per cent), when December 2024 returned the first positive reading of plus 0.1 per cent.¹

Net overseas migration reached 530,620 persons in the year to December 2023.² Population was growing faster than productive capacity. GDP per hour worked fell as deep as minus 5.05 per cent year-on-year in the March 2023 quarter and was still negative at minus 0.9 per cent in the December 2024 quarter.³

Canada's Parliamentary Budget Officer has published official modelling of the government's decision to cut immigration.⁴ The PBO's published analysis found the new immigration targets would reduce real GDP and simultaneously raise real GDP per capita, because the population shock was larger than the output shock.⁴

This is the independent analysis of the Office of the Parliamentary Budget Officer, not a think-tank projection. It is also modelled, not observed, and Canada's labour market differs structurally from Australia's, so the specific findings cannot be applied directly to Australia. What the Canadian modelling confirms is the directional logic: when population growth slows, per-capita and aggregate GDP can move in opposite directions, and official fiscal offices now treat that split as the primary welfare metric.⁴

Net overseas migration moderated to 300,955 in the year to December 2025, down from 530,620 in the year to December 2023.²

The RBA's September 2026 board statement noted that growth in output had slowed but was stronger than expected in the June quarter, while weak productivity growth continued to constrain potential growth.⁵ The Board lifted the cash rate by 25 basis points to 4.60 per cent at that meeting.⁵

The per-capita figures have improved in line with the moderation in migration: the December 2024 quarter returned plus 0.1 per cent, and March 2026 dipped back to minus 0.1 per cent before June 2026 returned to flat at zero per cent.¹

Three objections carry weight. First, GDP per capita is a mean, not a median: the six-quarter contraction may have been concentrated among existing lower-income residents rather than shared evenly, and the ABS does not publish a quarterly median income series that could settle that question.

Second, new migrants bring long-run fiscal and productive contributions that a short-run per-capita GDP window cannot capture; the contraction may reflect a temporary absorption cost rather than a permanent welfare loss. Third, the Canada PBO analysis is a modelled counterfactual, not a realised outcome, and structural differences between Canadian and Australian labour markets mean its findings should not be applied to Australia directly.⁴

The next ABS National Accounts release, covering the September 2026 quarter, will show whether the partial per-capita recovery that began in late 2024 has been sustained as the migration intake moderates further.¹ The RBA lifted the cash rate to 4.60 per cent on 29 September 2026, noting weak productivity growth continuing to constrain potential growth.⁵

The number missing from most of the migration debate is A$363: the real fall in each Australian's quarterly share of national output from March 2023 to the September 2024 trough, across six consecutive quarters during which aggregate GDP never once contracted.¹ It was in the National Accounts the whole time.

Just saying.
