Australia's total new capital expenditure (capex) experienced a 3.6% decline in the June quarter of 2026, reaching $50.952 billion on a seasonally adjusted basis. This decline follows a period of robust growth driven by significant investments in data centers. The largest contributor to this downturn was the information media and telecommunications sector, which saw a substantial drop of 30.2% for buildings and structures and an even more pronounced 53.0% for equipment, plant, and machinery in the June quarter.
This slowdown comes after record-breaking data center investment earlier in the year. In the March quarter of 2026, companies spent A$8.7 billion ($6.2 billion) on data center construction and server purchases, almost double the level in the final quarter of 2025. This surge had led to a 6.5% increase in Australia's total private investment in the March quarter, the highest since 2014, and saw the information media and telecommunications sector's capital expenditure rise by 96.1% to a new record level. The ABS noted that the investment in data center equipment, specifically server racks and processing equipment, had significantly boosted overall investment figures previously.
Despite the recent drop, the overall picture for data center investment remains strong in the medium term. Estimate 3 for total new capital expenditure in 2026-27 is projected at $200.7 billion, which is 15.5% higher than Estimate 2 for the same period. Similarly, expected capex for 2026-27 by businesses was revised up by 9.9% from the first estimate, driven by continued expectations of data center investment. While the June quarter saw a significant dip, the Australian Bureau of Statistics (ABS) had highlighted in earlier reports how data center investment was captured in their statistics and was a key driver of overall capital expenditure growth, particularly in New South Wales and Victoria.
Analysts have noted that Australia's data center boom has masked a broader economic slowdown. The recent dip suggests that while data center spending has been a major economic driver, its volatility can lead to fluctuations in overall capital expenditure figures. The Australian Financial Review reported in July 2026 that the surge in capital spending on machinery and equipment by IT businesses, reaching $5.2 billion in the March quarter, created a misleading impression of the broader economy's health, as other sectors experienced weakening business investment.
