Operational

Operational AirTrunk hyperscale campus in western Melbourne, distinct from MEL2. Operator disclosures establish reported capacity above 5 MW, but 185+ MW and 276 MW+ campus claims have unresolved scope differences and do not establish actual electricity consumption or commissioned IT load.

Statements retain their dates, definitions and development scope. Do not add these rows together.

Claim / measurement	Scope and status	As of	Evidence and accounting
≥276 MW Unspecified power	MEL1 total campus capacity in Australian platform announcement Planned · cumulative	2025-12-24	Conflicting claim ↗ Excluded from capacity totals. Announcement date. Source states 276 MW+ in a platform/deployable-capacity context; installed versus future scope and power basis are not defined. Planned status conservatively represents unverified end-state capacity.
≥185 MW Unspecified power	MEL1 multi-building campus total capacity Unknown · cumulative	2026-10-09	Conflicting claim ↗ Excluded from capacity totals. Retrieval date of undated facility page, not commissioning date. Source states 185+ MW; differs from December 2025 platform announcement.
185 MW Unspecified power	MEL1 campus total after announced expansion Planned · cumulative	2024-08-09	Reported claim ↗ Excluded from capacity totals. Announcement date; total campus capacity alongside construction of remaining phases. Source does not explicitly label the total as IT load.
>100 MW IT load	New IT load from remaining three of six MEL1 phases Planned · incremental	2024-08-09	Reported claim ↗ Excluded from capacity totals. Announcement date; construction expansion over the following 18 months was described. Completion was not established; overlaps the announced campus total.
≥20 MW Unspecified power	Completed MEL1 expansion announced in May 2023 Operational · incremental	2023-05-22	Reported claim ↗ Excluded from capacity totals. Completion announcement date; source states 20+ MW without identifying IT versus facility power. Included within campus capacity, not additive to later totals.
≥130 MW Unspecified power	MEL1 scalable campus capacity described in 2023 Planned · cumulative	2023-05-22	Reported claim ↗ Excluded from capacity totals. Announcement date; scalable to 130+ MW is an end-state statement, not then-operational load.
>50 MW IT load	Original Melbourne campus fully completed design Planned · cumulative	2017-11-16	Reported claim ↗ Excluded from capacity totals. Opening announcement date; source explicitly qualifies capacity as eventual full completion. Historical design claim superseded by subsequent expansion disclosures.
