NEXTDC hyperscale colocation campus in West Footscray, Melbourne. Existing operations coexist with construction and planned expansion. The current facility page advertises 225 MW IT capacity, while an April 2026 investor presentation distinguishes 40 MW built capacity from 185 MW in progress. These figures are not independently verified operational load.
