Artificial intelligence is changing how the world uses computing power. Queensland positions itself to join that transformation. The technology also requires an AI data center. It needs vast computing infrastructure.
That infrastructure is increasingly built as an AI data center. One of the most significant proposals in Australia is now taking shape in regional Queensland.
The Western Downs Digital Park, proposed near Dalby, could become one of the largest digital infrastructure developments ever seen in Australia. The proposal represents a significant change for regional Queensland, bringing together artificial intelligence, electricity generation, energy infrastructure, construction, telecommunications and regional employment.
The project is still subject to planning and government approvals, so it is important to distinguish between what has been proposed and what has already been built. Nevertheless, the scale of the proposal is substantial and has placed the Western Downs firmly into Australia’s emerging AI infrastructure conversation.
A $31.9 billion AI data centre proposal near Dalby
Singapore-based developer Zerra DC has proposed the Western Downs Digital Park on a 725.5-hectare site approximately 37 kilometers north-west of Dalby and around 250 kilometers north-west of Brisbane.
The proposed development is planned as a master-planned digital and energy precinct containing AI-ready data centers and associated infrastructure. The full development is estimated at approximately $31.9 billion. Current plans provide for four major data-center phases, with the possibility of further expansion identified in planning material.
The scale is difficult to comprehend in ordinary business terms. The initial proposal involves four data-center buildings, each designed around approximately 360 megawatts of capacity, with the overall development potentially reaching more than 1.4 gigawatts of IT capacity under the four-building proposal.
This is not simply another commercial building project. It is major infrastructure designed to support the computing demands of artificial intelligence and other digital services.
Why would an AI data center be built in regional Queensland?
The location is not accidental.
Western Downs has developed an unusual combination of characteristics that makes it attractive for energy-intensive industries. The region has a long history of electricity generation, gas infrastructure and large-scale agricultural production. It has also become a major location for renewable energy investment, including solar, wind and battery storage.
The proposed digital park is located close to major electricity infrastructure, including the Braemar substation, as well as several existing and proposed energy facilities.
This is one of the key reasons the Western Downs has become attractive to developers of large computing facilities. AI data centers require enormous amounts of reliable electricity, and the Western Downs already has an established energy ecosystem.
The region is therefore evolving from being primarily associated with agriculture and conventional energy production into something considerably more diverse.
AI data centre needs enormous computing power
The growth of AI is creating a completely different type of demand for infrastructure.
Training and operating sophisticated AI models requires large numbers of specialized processors running continuously. Cloud computing companies, technology companies and other organizations increasingly need access to high-performance computing infrastructure.
That means AI growth ultimately translates into demand for land, electricity, fiber-optic telecommunications, cooling systems, substations, batteries, buildings and highly secure facilities.
A data center is effectively a piece of industrial infrastructure for the digital economy.
Instead of producing physical goods, it processes and stores enormous quantities of digital information.
The importance of this distinction is becoming increasingly clear. AI may look like a software revolution, but supporting that software requires very physical investments in places such as regional Queensland.
Energy is at the center of the debate
The Western Downs proposal has also become part of a much larger national debate about how Australia should power data centers.
The electricity requirements of large AI facilities are substantial. Consequently, governments are grappling with how to balance economic development, electricity reliability, energy prices and emissions reduction.
Queensland has argued for flexibility in the way data centers source electricity, rather than requiring every facility to operate exclusively on renewable energy.
At the August 2026 meeting of National Cabinet, Queensland secured an exemption from the proposed national approach that would have required large data centers to rely exclusively on renewable energy. This means Queensland retains greater flexibility to use its existing energy system, including gas and coal, alongside renewable generation.
The issue is politically and environmentally contentious, but from a business perspective it highlights an important fact: energy availability is becoming a major factor in Australia’s ability to attract AI infrastructure investment.
Water is another important consideration
Electricity is not the only resource required by data centers.
Traditional data centers can use substantial quantities of water for cooling, which has raised concerns about whether large facilities are appropriate in areas where water security is already an issue.
The Western Downs Digital Park is proposing air-cooled technology rather than relying on conventional evaporative cooling. The project’s own plans state that water use during normal operation would primarily relate to staff and other operational requirements rather than cooling.
The developer’s current proposal indicates approximately 21 kiloliters of water per day for the first building, with around 8 kiloliters expected to be supplied through recycling. The remaining requirement would primarily involve treated rainwater, according to the project’s current planning information.
However, the project has still attracted questions about water, particularly during construction. The development application involves substantially greater temporary water requirements during the construction phase.
These questions will be important as the project proceeds through planning and community consultation.
Regional businesses could benefit
Perhaps the most interesting aspect of the proposal for Queensland businesses is not the data center itself.
It is the supply chain that forms around it.
A project of this scale requires enormous amounts of construction, engineering, electrical work, civil works, telecommunications, security, transport, accommodation and maintenance.
Regional businesses may have opportunities to provide services directly to the project or to contractors working on it.
Potential areas include earth-moving, concrete, fencing, electrical contracting, plumbing, equipment hire, transport, accommodation, catering, cleaning, security, landscaping, building supplies and specialized maintenance.
There will also be opportunities for businesses that can help existing regional companies adapt to the arrival of major infrastructure projects.
The Western Downs Regional Council has reported a development pipeline worth approximately $37.7 billion across the region, covering energy, housing, education, commercial development and infrastructure. The proposed digital park is therefore arriving in a region that is already experiencing substantial investment activity.
Housing and workforce will matter
Large industrial projects can create their own problems if local communities are not prepared for an influx of workers.
Housing is one of the obvious challenges.
The Western Downs Digital Park proposal acknowledges this issue and includes temporary accommodation and amenities for construction workers during peak periods. The developer has stated that it intends to reduce pressure on local housing by providing accommodation on site during periods of high demand and transitioning workers into the community as additional housing becomes available.
That could create secondary opportunities for regional accommodation providers, builders, property developers, transport companies and other service businesses.
It also means that the economic impact of the project could extend well beyond the boundaries of the proposed data-center site.
This is bigger than one data center
The significance of the Western Downs proposal is not simply that Queensland might receive a very large data center.
It demonstrates how the state’s existing strengths in energy, land and regional infrastructure could intersect with the rapidly growing digital economy.
Queensland has traditionally been associated with agriculture, mining, tourism, construction and energy. AI infrastructure adds another potential industrial sector to that mix.
The Western Downs is particularly interesting because agriculture remains fundamental to the region while energy infrastructure has expanded dramatically. The challenge will be allowing these industries to coexist rather than allowing one form of development to undermine another.
That balance will be closely watched by other regional Queensland communities considering similar investment.
What happens next?
The Western Downs Digital Park remains a proposed development and is subject to local and state government assessment and approval processes. The final design, staging, infrastructure requirements and timing could therefore change.
That is important because headlines about a $31.9 billion development can make it sound as though the entire investment has already been committed and construction is imminent.
It has not.
What does exist is a very substantial proposal backed by a developer specifically targeting hyperscale digital infrastructure and AI computing.
If the project progresses, its effects could extend well beyond Dalby. It could strengthen the Western Downs’ position as an energy and industrial center, create opportunities for regional suppliers and demonstrate that the next generation of Australia’s digital infrastructure does not necessarily have to be concentrated in Australia’s capital cities.
A new chapter for regional Queensland
For decades, the economic story of regional Queensland has largely revolved around agriculture, mining, energy and tourism.
Artificial intelligence introduces another possibility.
The computers running tomorrow’s AI systems may be located hundreds of kilometers from Brisbane, surrounded not by skyscrapers but by farmland, power infrastructure and regional communities.
That is what makes the Western Downs proposal particularly significant.
The development represents a convergence of two very different Queensland economies: the physical economy of energy, land, construction and agriculture, and the rapidly expanding digital economy of artificial intelligence and cloud computing.
Whether the full proposal ultimately proceeds at its currently proposed scale remains to be seen. But the fact that a project of this magnitude is being seriously proposed in regional Queensland is itself a sign that the geography of Australia’s technology industry is beginning to change.
Regional Queensland may not simply supply the food, minerals and energy that Australia needs in the future.
It could also help provide the computing power.
