Australia’s infrastructure challenge is changing

Australia’s infrastructure challenge is no longer simply a pipeline problem. It is increasingly a capital allocation problem.

Governments continue to face significant infrastructure demands across transport, water, energy, health, education and defence. However, more constrained fiscal conditions mean many projects are competing for a smaller pool of available funding. In this context, the core question has changed from whether infrastructure should be delivered to how projects can be funded.

How can projects be procured and structured to maximise value for money and investment over the longer-term?

Procurement and funding decisions are increasingly becoming investment decisions. The agencies that recognise and adopt this earlier will be better positioned to secure investment decisions, attract market confidence and deliver infrastructure outcomes that withstand growth scrutiny.

A more constrained fiscal environment

Governments are operating in a markedly different infrastructure environment from the one that shaped investment decisions over the previous decade.

Revenue growth has become less predictable as economic conditions soften and activity in key tax bases becomes more volatile. In some jurisdictions, this pressure is particularly visible where slower property market activity affects stamp duty collections while governments continue to manage elevated debt levels and rising interest costs. At the same time, expenditure pressures continue to rise and higher debt levels interact with tight monetary conditions and global market pressure on borrowing costs. These settings narrow fiscal flexibility and make the opportunity cost of every major investment decision more visible.

Alongside these operating pressures sits a material, competing capital agenda. Governments are being asked to invest simultaneously in large capex projects including energy transition infrastructure, water security, defence capability, health and education facilities and selected transport upgrades. Whilst infrastructure expenditure remains substantial, competition is increasing for scarce capital across jurisdictions.

There is a need to start thinking differently about infrastructure funding

The practical consequence is that every project must compete harder for approval and demonstrate a stronger value-for-money case across its full lifecycle. Treasury agencies, boards and regulators are applying increasing scrutiny to the assumptions that support business cases, including the robustness of cost estimates, risk allocation, the capacity of the market to respond and importantly, the extent to which alternative delivery or funding models could improve outcomes.

Why procurement and funding choices matter more now

The delivery model chosen for a project impacts far more than the contractual structure. It shapes how risk is shared, how incentives are aligned, how design development is managed, how quickly decisions can be made, and how much capability the client organisation must bring to the table.

Governments already have access to a wide spectrum of delivery models, ranging from traditional construct-only contracts through to highly collaborative alliance and partnership arrangements. Infrastructure delivery models should be selected through robust procurement options analysis rather than by precedent.

The challenge is not the availability of options but selecting the most appropriate model for the specific the complexity, uncertainty, interfaces and strategic objectives of the project.

The case for new delivery models

For straightforward, well-defined projects, traditional delivery models may still provide the best balance of cost control and accountability. However, many of the investments now facing governments are not straightforward. Large scale water security programs, renewable energy developments, defence investment and geographically dispersed capital programs involve uncertain scope, stakeholder sensitivities and interfaces, accelerated timeframes and evolving operational needs. Under these conditions, collaborative and programmatic models can offer significant advantages. Delivery partner and capability partner arrangements can strengthen client-side capacity where internal teams are stretched or where programs require sophisticated coordination across planning, procurement and delivery. Early contractor involvement can improve constructability, sequencing and risk pricing before governments commit to a final delivery structure. Alliance and incentivised models may be appropriate where uncertainty is high and better outcomes are more likely to come from integrated decision-making than from aggressive risk transfer.

Across Australia, agencies are increasingly exploring these approaches to address capability constraints, accelerate delivery and improve whole-of-life outcomes.  

Broader funding considerations

Funding decisions are equally important. Governments have historically relied heavily on direct budget funding supported by Commonwealth/State borrowing programs and these remain essential tools. However, constrained public balance sheets require a broader range of mechanisms that can either supplement public funding or alter how cash flows and risks are structured over time.

Which funding model for your project

No single funding model is universally appropriate

The right answer depends on the characteristics of the asset, the revenue profile, the allocation of demand and performance risk, the regulatory environment, and the government’s broader policy objectives. Public-private partnerships, for example, may be well suited to projects where long-term performance can be specified clearly and where private sector discipline can improve whole-of-life outcomes. Concession and availability-based structures can support accelerated delivery where there is a strong case for transferring specific risks and aligning payment to performance. Regulated or utility-style models may be more relevant where infrastructure serves an essential service monopoly and can be supported by an established regulatory framework. Value capture can contribute to funding where public investment creates identifiable private uplift, though Victorian policy work has consistently noted that it is generally a contributor to, rather than a full substitute for, core project funding. Hybrid models, including joint ventures, co-investment arrangements, developer contributions and institutional equity, can also be effective where projects sit at the intersection of public infrastructure, private sector need and commercial opportunity.

Procurement and funding must be considered together

Importantly, procurement and funding should not be considered in isolation. The two are deeply connected. A project’s delivery model influences risk pricing, financing confidence, governance requirements and the practical bankability of the structure. Likewise, the funding model often shapes what forms of procurement are feasible. A privately financed structure requires greater rigour in output specification, interface management and performance regimes than a directly funded capital works contract.

A long-term program delivery partnership may create the consistency and transparency needed to support alternative finance over time. In this sense, commercial strategy is most effective when procurement and funding are assessed together as part of one integrated delivery proposition.

Why advisory capability matters

This is where sophisticated infrastructure strategy and advisory support becomes increasingly important. Governments and public sector delivery agencies are being asked to navigate a wider menu of options at precisely the point when scrutiny is intensifying and internal capability is often stretched. Decision-makers need more than a generic list of models. They need a comprehensive assessment of which models are realistically available, the trade-offs they entail, what market response they are likely to generate and how they align with policy, governance and affordability constraints. That assessment must be grounded not only in theory but also in practical delivery experience across comparable programs.

How MBB can help

MBB supports government infrastructure clients across strategic advisory, commercial and transaction services, project development, project oversight, risk advisory, project controls and technical management. That breadth matters because the challenge governments face is rarely confined to a single decision point. It begins with strategy and business case development, extends through procurement design and transaction management, and continues into delivery governance, assurance and performance monitoring. The ability to connect these stages allows a more comprehensive assessment of both procurement methodologies and public and private funding options.

By helping clients move beyond default approaches and evaluate the full range of commercial pathways available, MBB assists agencies to identify commercial structures that are aligned to project objectives, market conditions and long-term value-for-money outcomes.

Procurement and funding models

The broader message is clear

Australia’s infrastructure challenge is no longer only a question of infrastructure need. It is a question of how governments prioritise scarce capital, how projects can be structured to achieve long-term value for money and how they unlock delivery pathways that are robust in a fiscally constrained environment.

Procurement and funding decisions are no longer implementation decisions. They are investment decisions. Agencies that assess these options early and rigorously will be better placed to secure investment approval, attract market confidence and deliver outcomes that stand up to public scrutiny.
