Ten data centre projects and stages across four states are due in 2027, four of them campuses of 200MW or more.
Five follow in 2028, four in New South Wales and one in South Australia.
Headline capacity due to start is about 1.7GW in 2027 and 1.3GW in 2028, including several full-campus sizes.
New South Wales carries 13 of the 25 projects with a published date, with projects due in every year from 2026 to 2029.
Large campuses without a date include gigawatt-scale proposals in New South Wales, Victoria, South Australia and the Northern Territory.
This guide lists every Australian data centre project and stage with a published target year, taken from the operator, its builder or press reporting, with sources under each table. Financial-year dates are converted to the calendar months they cover. Sites already operating are in the list of data centres in Australia.
Ten projects and stages are due in 2027 and five in 2028, and New South Wales holds eight of the 15. Two Sydney campuses carry 2029 dates, and no project yet has a published 2030 date.
Year | Projects and stages | By state |
|---|---|---|
2026 | 8 | NSW 3, Victoria 2, Tasmania 1, WA 1, NT 1 |
2027 | 10 | NSW 4, Queensland 3, Victoria 2, Tasmania 1 |
2028 | 5 | NSW 4, South Australia 1 |
2029 | 2 | NSW 2 |

The next table groups headline capacity by the year each project's stage is due, using the published figure for that stage, or for the whole project where no stage figure is given. Most campuses come online in stages over several years, and each company measures capacity its own way.
Year | Headline capacity due | By state (MW) |
|---|---|---|
2026 | About 90MW, plus three projects without a MW figure | Tasmania 44, NSW 26, Victoria 20, NT 1.5 |
2027 | About 1.7GW | NSW 938, Queensland 381, Victoria 355, Tasmania 1 |
2028 | About 1.3GW | South Australia 800, NSW 516 |
2029 | About 0.7GW | NSW 704 |
Source: capacity as published by each company, on different bases: planned capacity, IT load (the power available to computing equipment), first phase or whole campus. S4, S7, MEL2, the SYD3 extension and IREN Bundey are full-campus sizes that will be built over years, so the totals are indicative and do not measure capacity switching on in that year. Victoria's largest projects have no date yet: Syncline Energy's Plumpton proposal at 2.4GW, NEXTDC M5 at up to 1.2GW, CDC Laverton at more than 400MW, STACK MEL02 at 252MW and NEXTDC M4 at 150MW.

NEXTDC and DigiCo added their 2026 capacity inside existing sites, and Macquarie Data Centres says the power and water supply for the full IC3 SuperWest building has been commissioned.
Firmus, one of the neocloud providers in Australia that rent out the computing capacity inside an AI data centre, said on 27 August that its Melbourne cluster had been installed, commissioned and handed over.
Canberra Data Centres (CDC) supplies the data centre infrastructure for Firmus's Project Southgate. Its Brooklyn campus in Melbourne, operating since 2024, was officially opened by Premier Jacinta Allan in February 2026.

2029 and 2030: two Sydney campuses, then forecasts
Two Sydney campuses carry a 2029 date. No Australian operator has published a 2030 opening date, so 2030 is covered by forecasts.
Project | Capacity as published | When |
|---|---|---|
CDC Marsden Park, Western Sydney | 504MW approved across six buildings | Multiple buildings, April 2027 to March 2029 |
Macquarie Technology campus, Macquarie Park, Sydney | Proposed 200MW | First completion late 2029, subject to approvals |

Australia intends to legislate data centre standards in early 2027, and most of the pipeline would be built under them.
The Australian Energy Market Operator (AEMO) forecasts data centre electricity use in the National Electricity Market, the grid serving every state except Western Australia, to triple to about 15TWh in the year to June 2030. The forecast for total operating capacity, reaching 3.2GW in 2030, is set out at the end of this guide.

Operating capacity is forecast to reach 3.2GW by 2030
Total operating capacity for each year is published only as a forecast, and only nationally and for Sydney and Melbourne. Industry body Data Centres Australia and researcher DC Byte forecast it on one measure, the power available to servers in finished data halls.
Year | Australia | Sydney / Melbourne |
|---|---|---|
2025 | 1.4GW | 0.8GW / 0.4GW |
2026 | 1.7GW | 1.0GW / 0.5GW |
2027 | 1.9GW | 1.2GW / 0.6GW |
2028 | 2.3GW | 1.5GW / 0.7GW |
2029 | 2.7GW | 1.7GW / 0.9GW |
2030 | 3.2GW | 2.0GW / 1.1GW |

The report does not forecast other cities or states, and its figures are rounded to 0.1GW, so the rest of the country cannot be worked out by subtracting Sydney and Melbourne from the national total.
