Queensland’s record infrastructure spend brings delivery challenges into focus

The Queensland Government’s 2026-27 Budget reinforces the state’s position as one of Australia’s most significant infrastructure growth markets.

With substantial investment committed across transport, health, housing, energy, education, and Brisbane 2032 Olympic and Paralympic Games (Brisbane 2032) infrastructure, the scale of the pipeline is clear.

But the biggest takeaway isn’t the funding. From an infrastructure advisory perspective, it’s the scale of the delivery task ahead that may prove the greatest challenge - and opportunity.

Headline investment across sectors

The scale of investment is significant. The Budget delivers Queensland’s largest-ever infrastructure pipeline:

• $119.2 billion capital program over four years, including $55.9 billion through the Queensland Transport and Roads Investment Program, underpinning major road, rail and transport delivery across the state
• Expanded social infrastructure investment, including $4 billion in health capital expenditure in 2026-27 under the Hospital Rescue Plan and $1.5 billion in education infrastructure in 2026-27, alongside a $5.7 billion four-year social and community housing program and the $2 billion Residential Activation Fund to unlock new housing supply
• Investment in Brisbane 2032 venues and athlete villages is also progressing, with $765 million allocated in 2026-27, including $417 million for venues and $348 million for athlete villages
• Renewed focus on water security and resilience, including $276.2 million in 2026-27 for dam improvement programs.

These initiatives reflect a broad and coordinated push to support population growth, improve connectivity, and deliver essential infrastructure across the state.

From funding to delivery

Queensland is now managing one of the largest infrastructure pipelines in the country while simultaneously preparing for Brisbane 2032, addressing housing supply constraints, expanding health capacity, and delivering major regional projects. At this scale, the conversation is increasingly shifting away from identifying funding priorities towards understanding how projects will be delivered.

The challenge is not simply the volume of work, but the fact that multiple large and complex programs are being delivered concurrently, often drawing on the same labour pools, supply chains and delivery capability.

A constrained delivery environment

Delivering this infrastructure pipeline will occur in a market that remains constrained.

Workforce shortages continue to impact construction, engineering and project management capability, with sustained demand across both public and private sector projects. At the same time, supply chain conditions, while improved, remain uncertain, particularly for large-scale projects that rely on specialised materials and long lead times.

Cost escalation also remains a central consideration, with input costs, financing conditions and risk allocations continuing to evolve. This creates additional pressure on project feasibility, budgeting and delivery outcomes, particularly where projects have long planning and construction timelines.

As highlighted in BDO’s 2026 Construction Report, cost pressures, labour shortages and supply chain constraints continue to shape project delivery across Australia, reinforcing the importance of realistic budgeting and risk allocation.

In addition, the scale of the pipeline places increased demands on procurement frameworks and delivery models. Traditional approaches may not always be well-suited to managing concurrent programs of this size and complexity, particularly where risk allocation, contracting structures and approval processes have not adapted to current market conditions.

Implications for government and industry

The key questions are now more practical than conceptual.

• Which projects are genuinely ready to proceed?
• How should the pipeline be sequenced to avoid crowding the market?
• What procurement and delivery models will give industry enough certainty to price and participate confidently?
• How can government ensure scarce capital and delivery capability are directed to the projects that will deliver the greatest economic, social, and service outcomes?

Recent experience across major transport, health, housing, and Brisbane 2032-related programs show success is increasingly dependent on early market engagement, realistic risk allocation, robust business cases and disciplined program-level prioritisation.

The opportunities for contractors, consultants, investors, and asset owners remain significant. However, participation in the pipeline will require a more considered approach, with a stronger focus on risk management, capability alignment and delivery performance.

For government, this will likely require greater emphasis on program-level coordination, including how projects are prioritised, sequenced and delivered across agencies.

Procurement strategies will also need to evolve to support collaboration, incentivise productivity and better manage risk in a changing delivery environment.

The shift to execution

Delivering the infrastructure pipeline outlined in the Budget will depend on the ability of both government and industry to move from project announcements to disciplined execution.

Based on our work across major infrastructure business cases, project validation, procurement strategy and delivery assurance, the most successful programs are those that make early, evidence-based decisions about scope, sequencing, risk allocation, market engagement and governance. Robust front-end planning is therefore critical to testing whether projects are genuinely investment-ready, understanding market capacity, structuring procurements to attract competition, and maintaining a clear line of sight between investment decisions and long-term economic, social, and service outcomes.

How BDO can help

Queensland’s infrastructure ambition is clear, with a pipeline that reflects both the scale of growth and the importance of long-term investment across the state. The focus now turns to execution, and how effectively these commitments can be translated into outcomes in a constrained and increasingly complex delivery environment.

BDO’s project and infrastructure advisory team works with government, investors, and delivery partners to support capital decision-making and improve delivery performance across complex infrastructure programs.
