OpenAI and NextDC Sign MoU for A$7 Billion AI Supercluster in Sydney

Executives say the project’s large power demand will spur new investment in renewable energy.

Overview

  • The memorandum of understanding outlines collaboration on a next‑generation hyperscale AI campus and large GPU supercluster at NextDC’s S7 site in Eastern Creek, which has potential capacity of about 550 megawatts.
  • The venture is reported at A$7 billion and is positioned to host advanced AI models for OpenAI’s ecosystem.
  • NextDC shares rose as much as about 11% on the announcement, making it one of the day’s top performers in Sydney trading.
  • The plan coincides with OpenAI opening its first Australian office, and the federal government welcomed the project as a source of thousands of jobs during development and operations.
  • NextDC’s chief executive and the industry minister highlighted the need for more renewable power for data centers, while NextDC recently lifted FY26 capex guidance by A$400 million to accelerate capacity.
