What were the biggest Australian data centre and AI infrastructure announcements in the last 90 days?

Microsoft’s A$25 billion commitment on 23 April 2026, AWS’s nine renewable PPAs adding 430MW on 16 April, the Anthropic-Australia MoU under the National AI Plan, the Department of Industry’s national expectations framework on 23 March, NVIDIA GTC 2026 launching the Vera Rubin platform, IREN’s US$3.4 billion NVIDIA contract and 2028 Australian plan, and the first independent DCA × DC Byte forecast on 28 April.

How much new capital was committed to Australian AI infrastructure this quarter?

Microsoft committed A$25 billion to 2029. AWS sits within a A$20 billion infrastructure plan with A$2.8 billion in local renewables. OpenAI’s A$7 billion NEXTDC S7 deal continues to deploy. NEXTDC opened a A$2.2 billion capital programme. Firmus is backed by a US$10 billion debt facility. CDC signed a single 555MW hyperscale contract worth “tens of billions” over 30 years. Quarterly committed spend now exceeds the entire 2025 local colocation market revenue of US$2.1 billion.

How are AI factories changing the scale of Australian data centres?

NVIDIA GTC 2026 (Vera Rubin, 800 VDC, megawatt-scale liquid cooling) is the new baseline. Per-site capacity now routinely exceeds 100MW: GreenSquareDC SYD1 96MW, CDC Perth 200MW, NEXTDC M3 225MW by 2027. Only 3 of 162 operational sites exceed 100MW today, but 15 of 90 pipeline projects do.

Why is energy now the binding constraint on Australian data centre growth?

AGL’s 34TWh demand forecast sits 17 per cent above AEMO’s 29TWh and seven times current sector use of 5TWh. The Australian Industry Group brackets the next five years at 35TWh to 70TWh. Morgan Stanley estimates A$8 to A$42 billion of new generation by 2030. The Commonwealth’s Expectation 2 requires new projects to add new clean energy rather than draw from existing supply.

Five themes from a remarkable quarter for Australian data centre and AI infrastructure | Australia Data Centre Index

Inside 90 days: Microsoft A$25 billion, AWS 430MW of new renewables, NEXTDC's A$2.2 billion capital plan, CDC's 555MW hyperscale contract, the first DCA × DC Byte forecast (1.4GW today, 3.2GW by 2030), and a 5TWh AGL/AEMO split on grid demand.
