Australia’s next wave of innovation will depend on how clearly policy separates generic data centres from high‑performance computing (HPC). Bundling them into one “digital infrastructure” bucket directs capital to cloud‑style capacity while underinvesting in leadership‑class HPC needed for frontier AI, climate modelling, defence and advanced industry. The piece argues for explicit “AI‑ready HPC” and “AI‑capable cloud” tracks in national strategy, funding and governance.

The productivity lag from AI reveals competing logics: automation that replaces labour to cut costs versus augmentation that expands capability to create value. For innovation ecosystems, this choice is existential. Strict safety regulations risk creating moats favouring large incumbents, while unrestricted deployment threatens research quality. The narrow path requires public interest AI infrastructure, risk-weighted governance, and incentives rewarding high-impact discovery
