Data Centres Australia and DC Byte have published the first issue of the Australian Data Centre Forecast Report, drawing on DC Byte's coverage of more than 8,300 facilities across 135 countries. On the headline numbers, national operational capacity is projected to move from 1.4 GW in 2025 to 3.2 GW by 2030.
Australia now has a unified phase framework that distinguishes capacity at different stages of certainty.
How the phase framework works
DC Byte segments capacity into four phases, each with specific evidentiary thresholds:
Phase | What it measures |
Operational | IT load of fitted-out data halls available for use |
Under Construction | IT load of halls undergoing mechanical and electrical fitout |
Committed | Projects with land, power, permits secured, or operators with reliable delivery track records |
Early Stage | Projects that have not yet secured all elements required for development |
Aggregated, the four phases produce a Pipeline Total. The framework's value is in the segmentation. Of Australia's 21.6 GW total pipeline, only 1.5 GW is operational today and 3.1 GW is committed with land, power, and permits secured. The remaining 16.8 GW is early-stage, meaning it may or may not be built.
What the report shows
National capacity pipeline by phase (GW)
Phase | National | Sydney | Melbourne |
Operational | 1.5 | 0.8 | 0.4 |
Under Construction | 0.2 | 0.1 | 0.1 |
Committed | 3.1 | 1.9 | 1.0 |
Early Stage | 16.8 | 8.6 | 7.5 |
Pipeline Total | 21.6 | 11.4 | 9.0 |
Operational capacity forecast (GW)
Year | National | Sydney | Melbourne |
2025 | 1.4 | 0.8 | 0.4 |
2026 | 1.7 | 1.0 | 0.5 |
2027 | 1.9 | 1.2 | 0.6 |
2028 | 2.3 | 1.5 | 0.7 |
2029 | 2.7 | 1.7 | 0.9 |
2030 | 3.2 | 2.0 | 1.1 |
Australia is currently home to 162 operational data centres, with 60 sub-1 MW facilities, 99 between 1 and 99 MW, and 3 above 100 MW. The 90 pipeline projects show a structural shift toward larger scale, with 15 of 90 above 100 MW. This is the signature of hyperscale and AI-aligned demand, and it aligns with the recent capital programmes covered in Microsoft's $25 billion Australia AI investment and NEXTDC's $1.5 billion retail offer.
Why the framework matters for policy
The NSW Investment Delivery Authority's classification of $40.7 billion of proposals as premature or speculative, alongside $51.9 billion fast-tracked, maps closely to the distinction between Early Stage and Committed capacity. The Commonwealth's National Interest Framework, released 23 March 2026, sets approval prioritisation against demonstrated readiness on energy, water, and economic contribution. Both frameworks reward delivery confidence.
For the NSW Parliamentary Inquiry into Data Centres, which has received over 120 submissions, the phase framework offers a way to interpret the much-cited pipeline figures with greater precision. Aggregate pipeline numbers describe investment intent. Committed and Operational numbers describe what is actually delivering capacity to the grid and the market.
CertifiedStrategic's maps
The report's national and capital city totals provide a forecast benchmark. Site-level detail on where capacity sits and which corridors are growing is shown on the Sydney data centre infrastructure map and the Melbourne data centre infrastructure map.
The Sydney map tracks 58 facilities across approximately 1.3 GW operational and a further 5.2 GW announced pipeline across the Western Sydney corridor and Greater Sydney. The Melbourne map covers four corridors (Tullamarine, Western Melbourne, Port Melbourne, North Melbourne) totalling approximately 1.5 GW operational and a 4.7 GW pipeline.
Capacity figures on the maps reflect operational IT load as disclosed by operators on their official location pages, ASX filings, and recent corporate announcements. Where operators publish multiple figures (such as design capacity versus contracted capacity), the most recent operator disclosure is used. Pipeline figures draw on operator announcements, NSW and Victorian planning portal records, Investment Delivery Authority endorsements, and network operator connection data. Other published forecasts of the Australian market may use different scoping definitions and verification thresholds; the forecast and the maps are best read as complementary views.
What the framework enables next
A shared phase methodology is a maturity signal in its own right. Markets that distinguish committed capacity from early-stage proposals attract international capital because they reduce planning ambiguity. They also support better grid planning, because utilities can prioritise the 3.1 GW of nationally Committed capacity ahead of the 16.8 GW Early Stage tier. Recent moves like Amazon's 430 MW of battery-backed renewable PPAs and AirTrunk's Lumina CloudInfra acquisition are visible cases of capacity moving from Early Stage and Committed into delivery.
The forecast is described as bi-annual, which sets up an ongoing rhythm of revision against actual delivery. As Operational and Under Construction tiers grow over the next two years, the report becomes a tracking instrument rather than a one-off snapshot.
What to watch through 2026
· NSW Data Centre Consultation closing 8 May 2026. Sets the planning template most other states will follow.
· NSW Legislative Council Inquiry hearings opening 1 May 2026. First detailed public examination of the supply-and-demand reconciliation.
· Quarterly capacity announcements from listed operators. NEXTDC's S4 Sydney programme and Sharon AI's NEXTDC M3 deployment are early indicators of how Committed capacity converts to Operational delivery.
The DCA × DC Byte forecast gives Australia a baseline for those conversations. The next two years will show how the methodology performs when measured against actual delivery.
