Melbourne, Victoria, Australia
Southgate Melbourne is an operational AI data center with AI chips owned by Firmus. It hosts an estimated 46k H100-equivalents of compute, supported by 41 MW of IT power at a capital cost of $1.6 B. We estimate that it uses Nvidia B300 chips.
The timeline of IT power and compute capacity is based on satellite imagery and company disclosures.

Building 1 site is cleared/vacant land; no construction visible yet (based on Google Earth historical imagery).
Satellite imagery shows 30 fully installed air-cooled chillers (20 fans each) on the roof, with room for many more. In the same month, Firmus reported that Project Southgate's "first stages are under construction in Tasmania and Melbourne". So we don't think the Southgate part of the building is operational yet.
Building 1's cooling capacity increased to 53 air-cooled chillers (20 fans each), up from 30 in Oct 2025. This is more than enough for the announced 18,400 GB300 GPUs, but construction does not quite look complete, so we expect another 3 months until it's operational.
Building 1 is operational (estimate). No additional chip deployment beyond the 18,400 GB300 GPUs has been publicly confirmed, so we continue to report the disclosed capacity allocated to Project Southgate, rather than speculate on further buildout.
