CommBank puts Australia’s data centre build out at around $150 billion by 2030, and around $220 billion if the whole pipeline were completed. Roughly six gigawatts is proposed, about four times what was operating at the end of 2025. New South Wales carries around half of it and Victoria around a quarter, with South Australia, Western Australia, Queensland and the Northern Territory growing because their grid constraints are less severe.
What Australian businesses deliver
The processors, servers and networking equipment are imported and make up most of the facility cost. Almost everything else is delivered by Australian businesses. Civil and structural, high voltage and low voltage electrical, mechanical and cooling, fire, security, commissioning, and then a maintenance and shutdown programme for the life of the site.
How a data centre gets built, and who buys what
The developer or operator secures land, power and water, then appoints a head contractor. The head contractor lets the packages in a defined order through an estimator or package manager, civil and structural first, then electrical, mechanical and cooling, then fire, security and commissioning. Once live, the operator runs the site on multi year maintenance, cleaning and security terms managed by a critical environments or facilities manager. Three buyers, at three stages, each with a different reason to say yes. Win Work watches planning approvals, contractor appointments and job ads for critical environments roles to find each of them in time.
Why the constraints are the opportunity
The report names grid connection, water, land, construction materials and skilled trades as the binding constraints on the pipeline. A constraint is a scope somebody has to deliver, and the businesses that can deliver it are in short supply. A fabricator with switchroom experience, an electrical contractor with high voltage tickets, a mechanical crew that has commissioned cooling plant and a maintenance business that can hold a critical site are all rarer than the demand for them.
What this means for a business in New South Wales or Victoria
Half of what is proposed is in New South Wales and a quarter in Victoria. For an industrial or construction services business in either state, this is a new category of buyer that did not exist at this scale five years ago, with sites being approved and contractors being appointed now. The buyers are named on planning applications and in appointment announcements. Much of the work they will let sits with Australian industrial and construction services businesses.
