AUD 1.59M on-prem.
AUD 400–700k sovereign in the cloud.

The recommended 8× H200 stack lands at AUD 1,590k over three years (range 1,270k–2,050k). An Australian-region cloud-sovereign deployment — Claude Opus 4.7 on AWS Bedrock-Sydney or GPT-5.5 on Azure Australia East under negotiated DPAs — lands at AUD 400–700k and closes the capability gap.

And cloud-sovereign closes the capability gap on §II, because the same DPA buys access to GPT-5.5, Claude Opus 4.7, or Gemini 3.1 Pro at the frontier rather than three to six months behind it.

SourceOn-prem frontier LLM briefing, §3.1 Stack A and §4 Dominant alternatives. Hardware quotes from Australian distributors (Hyperscalers AU, Broadberry AU, XENON) or reseller-indication estimates marked as such — NVIDIA does not publish HGX list prices. USD/AUD planning rate 1.50, above RBA spot ≈ 1.38 to absorb FX and procurement variance. Cloud-sovereign range from the briefing's §4 paragraph and reflects typical 30–50% of on-prem TCO for this workload profile.
