Australian Prime Minister Anthony Albanese's push to regulate artificial intelligence infrastructure is encountering significant technical headwinds that threaten to derail data centre construction in Sydney and Melbourne.

The government's new policy framework, which includes a mandate for data centres to become net energy generators, is being scrutinized for its practical feasibility in the current grid environment.

The policy aims to establish regulatory guardrails for the AI sector before its societal and economic impact becomes unmanageable.

However, industry observers warn that the technical requirements for data centres to generate their own power may be overly ambitious given existing infrastructure constraints.

This tension between regulatory ambition and engineering reality is creating uncertainty for developers planning major builds in Australia's two largest cities.

The Reserve Bank of Australia has previously flagged that the rapid expansion of data centre investment is creating new headwinds for its inflation mandate.
