National operational capacity
≈ 1,500 MW IT · 31 March 2026
162 centres · Operational data centres in source inventory
Data Centres Australia and DC Byte estimate Australia had about 1.5 GW of operational IT capacity across 162 data centres at 31 March 2026. This provides a national market benchmark alongside the Atlas’s partial site-level evidence.
The national estimate is a separate benchmark. It is not added to the documented capacity above, whose coverage and observation dates differ.
Operational capacity is the IT load supported by fitted-out halls available for use, not necessarily utilised capacity or live electricity demand. This rounded industry estimate has its own inventory and date. It is not an independently reconciled Atlas facility total and is never added to site subtotals or assigned to map pins.

Approximately 130 MW of operating primary ICT capacity, derived from CDC’s Victorian regional total. Brooklyn is CDC’s only operating Victorian campus; the government confirms two operational facilities, while the September investor update places Laverton’s first opening in late FY27. The regional figure is rounded to the nearest 10 MW and is assigned once to the campus, without duplicating BK1 and BK2.
As at
Operating leasable capacity: primary ICT capacity that is contractable or generating revenue. Source rounds each regional figure to the nearest 10 MW. This is capacity available for customers, not electricity consumption, contracted capacity or actual utilisation. Named-site capacity forms part of this portfolio total and is counted once.

Australian built capacity derived from 287.9 MW consolidated fitted-out capacity less 10 MW in Kuala Lumpur. The regional table rounds Australia to 278 MW. Built means designed power of fitted-out halls; further customer infrastructure can be required.

Sydney · New South Wales
Effective date not stated
Conservative 121 MW IT lower bound for the completed SYD1 campus. The final building was completed in July 2022 at a reported 130 MW IT campus scale. The later platform announcement states 121+ MW, while the current campus page retains 130+ MW. Their difference is not explained. No hosted tenant or final phase is added separately.
Sydney · New South Wales
As at
Approximately 50 MW for the first two opened phases, derived from the operator 120+ MW campus total less its 70 MW final-two-phase expansion. Both earlier phases were already open in June 2023. Contemporaneous reporting identifies the campus electrical basis as IT load. This rounded derivation is separate from the completed 30 MW phase 3 increment; phase 4 is not assumed operational.

Only the third-phase 30 MW increment is evidenced here. AirTrunk confirms completion; contemporaneous DCD reporting explicitly identifies the same expansion as IT capacity. Neither source establishes that the whole 120+ MW campus was fitted out.

Operator reports 30 MW of operating white-space IT load in Sydney, at 100% share, rounded to whole MW. The investor table counts four data centres; the public profiles do not allocate the reported capacity among buildings. All known Sydney records are covered so any later named-site allocation is deducted, never added on top. No occupancy discount is applied: installed capacity includes available space.
As at
Latest separately disclosed Melbourne white-space IT load: 9.6 MW at 31 December 2025 across two investor-report data centres. Later reports combine Melbourne with other APAC markets. Public MEL10/MEL11/MEL12 profiles do not establish how this operating figure is allocated; their design ratings cannot be added on top.
6 MW at named sites + 15 MW portfolio balance = 21 MW documented.

Macquarie commissioned environmental assessment states IC2 was operating at full capacity, unlike partially operating IC3 East. The operator identifies IC2 capacity as6 MW IT. This is allocated within the21 MW installed Australian portfolio, not added on top of it.
As at IT basis inferred from sources
FY26 issuer presentation reports 21 MW installed across Macquarie Park, Canberra and Sydney CBD. IC3 SuperWest and METC are future additions, excluded from this installed figure. IT basis is supported by the presentation using additive 47 MW SuperWest IT capacity and the operator IT-load specifications; the 21 MW sentence itself says installed capacity, without repeating IT. Named-site allocations are included within the 21 MW portfolio, with only the unallocated balance additional to them.
Site allocation: Macquarie IC2 Macquarie Park (6 MW).
14 MW at named sites + 0 MW portfolio balance = 14 MW documented.
Sydney · New South Wales
As at IT basis inferred from sources
The operator reports more than 14 MW operating at SY9x, distinct from the eventual >28 MW facility. Atlas interprets this as customer IT capacity from xScale’s commercial phase reporting, the operator’s IT-load terminology and the planning distinction between 45 MW gross and 30 MW IT design. This electrical-basis interpretation is inferred across sources, not a directly stated 14 MW IT specification. The separate 14 MW second phase remained under development at 30 June 2026.
5.4 MW at named sites + 0 MW portfolio balance = 5.4 MW documented.

Derived pre-existing ADL01 IT capacity: the operator states ADL02 adds 4 MW and the combined two-building Kidman Park campus reaches 5.4 MW total IT load. 5.4 minus 4 equals 1.4 MW. Counted once with the separate ADL02 increment.

NEW ZEALAND · OTHER PUBLISHED MEASURES
New Zealand sources also report facility power and built portfolio capacity. Those measures help describe the market, but their electrical definitions differ from the leasable IT figure above. They are shown separately.
NZTech's 2025 report estimates 56 operating data centres and 104 MW of deployable whole-facility power, including cooling and support systems.
How to read this: This is estimated power for the whole facility, not installed customer IT load. The report uses operator inputs and proxies, excludes duplicated leased colocation capacity, and has a different inventory and date from the Atlas. It cannot be added to or subtracted from the 2026 CDC ICT portfolio figure.

Executive summary: 56 data centres and 104 MW; New Zealand Data Centre Locations (July 2025 input); Understanding deployed capacity and appendix Calculating Current Deployable Capacity.
Spark reported over 23 MW built across the 11 operating facilities that were transferred to TenPeaks in January 2026.
How to read this: The primary disclosure does not say that the 23 MW is IT load or that it is comparable with CDC's leasable primary ICT measure. South Takanini's 12.3 MW is inside this transferred estate, not additional. It is excluded from Atlas operating IT totals until the power boundary is documented.

Computing power, also called IT power, supplies servers, GPUs, storage and networking equipment. It describes the capacity available for that equipment, not current electricity use or how much is leased. Whole-building power also includes cooling and other overheads.
The totals combine dated disclosures, so they are not a complete census at a single point in time. ≈ marks approximate values; ≥ marks minimum disclosures. Operators without a comparable figure are not assigned zero. Portfolio balances appear here without being assigned to map pins.
