Beyond the trophy assets: Australasia’s middle-market opportunity
The large-cap end of Australian infrastructure is crowded, expensive and slow to turn over. The middle market is where structural demand, less competition and manager skill can still create value.
Why Australasia
In the global search for infrastructure assets, capital has crowded into large, defensive assets in major developed markets, compressing yields and intensifying competition for a relatively small pool of opportunities. Yet some of the most compelling opportunities today can be found in markets where structural growth, institutional stability and fragmentation provide fertile conditions for value creation.
Australia and New Zealand stand out in this regard. Both markets combine characteristics that are increasingly difficult to find elsewhere: political stability, strong rule of law, long-term infrastructure demand and resilient economic growth.
Australia, for example, has enjoyed close to three decades of uninterrupted economic growth, and the International Monetary Fund projects real GDP growth of around 2% a year through to the end of the decade – ahead of the euro area and Japan over the same horizon.1 Its population reached 27.7 million in September 2025, growing 1.6% year on year, and is expected to exceed 34 million by 2040.2 That pairing of economic and demographic expansion underpins a durable demand profile for the essential services infrastructure provides.
Despite the attention on large trophy assets, we see more compelling opportunities in the middle market, where competition lessens and the levers to create value multiply. This is the segment we have invested in for more than three decades.

A misread market
The typical view of Australian infrastructure – mature, competitive, well banked – does not capture the diversity of opportunities on the ground. The country has been one of the three most active infrastructure markets in the world by deal value over the past five years, behind only the United States and the United Kingdom, with deal volumes approaching US$700 billion over that period.3 Investor sentiment echoes that depth: the 2025 Australian Infrastructure Investment Monitor found Australia had overtaken North America and Europe as the most attractive region for infrastructure investment, with 85% of surveyed investors highly likely to commit capital over the next three years.4 Energy assets dominate stated preferences – grid storage and firming ranked highest – while data centres also sit at the top tier of favoured segments.
The same investors point to a thin pipeline and intense competition as their main frustrations. That is largely a feature of the large-cap segment, where a limited pool of trophy assets, many privatised in the 1990s and 2000s and since held by long-term owners, turns over infrequently. By contrast, the middle market sees around 2.7 times as many transactions as the large-cap segment (deals above US$750 million).5 Around three-quarters of Igneo’s transactions in the region over the past five years have been bilateral deals or add-ons to existing platforms. The first deal in a sector may be competitive; the ones that follow generally are not.
| Large-Cap "Trophy Assets" | Middle Market Infrastructure |
|---|---|
| Limited asset pool | Large, fragmented opportunity set |
| High competition | Fewer competing bidders |
| Auction-driven transactions | Bilateral and relationship-led deals |
| High entry valuations | More attractive pricing |
| Infrequent turnover | Higher transaction volume |
| Limited value creation levers | Multiple operational improvement levers |
| Buy and hold | Buy, build and scale |
"The 2025 Australian Infrastructure Investment Monitor found Australia had overtaken North America and Europe as the most attractive region for infrastructure investment."
Many markets within the market
Australia and New Zealand are not single, homogeneous markets but collections of regional and sub-sector niches. Regulation frequently sits at the state or local level, customer bases are regional, and competitive dynamics vary from one area to the next. The result is a long tail of mid-sized and smaller businesses that national or global players cannot serve efficiently, with deal sizes that are too small for the largest managers to source and manage economically, but a rich hunting ground for a specialist with local networks.
New Zealand illustrates the point. In character it closely resembles Australia: low geopolitical and sovereign risk, sound institutions, high-ranking governance, strong renewable resources and the foundations of energy independence. It is smaller – representing around a third of our deal flow in the region – and is sometimes treated as the forgotten cousin by other investment managers. But with less competition, deals can be shaped and structured rather than simply bid for.
New Zealand’s public finances also frame the opportunity. The country has invested around 5.8% of GDP a year in infrastructure over the past two decades – among the highest rates in the OECD – yet ranks near the bottom for the efficiency of that spending and fourth-to-last for asset management.6 Its National Infrastructure Pipeline has close to 12,000 initiatives worth a combined NZ$275 billion, more than two-thirds of which by value are not yet fully funded.6 Estimates put the country’s infrastructure funding deficit at around NZ$210 billion.7 With many councils close to their borrowing limits, private capital has a key role to play in well-structured, right-sized projects.
Where structural demand meets cyclical opportunity
Several long-running themes are driving sustained capital requirements across the sectors we focus on – energy, digital, transport and waste and water. Arguably the most striking of these is energy, where structural demand, cyclical dislocation and capital scarcity have converged.
Renewable generation accounted for a record 46.5% of Australia’s national electricity production in the first quarter of 2026, up from 42.5% a year earlier, with the federal government targeting 82% to come from renewables by 2030.8 Australia has the highest solar generation per capita in the world, more than six times the global average, and around 43% of households have rooftop solar.9 Layered over that demand is a cyclical opening: after a period of historically high valuations, mispriced risk has emerged as capital has become scarcer, creating attractive entry points for disciplined investors.
"None of these sub-sectors stands entirely alone; the linkages across energy, digital and waste and water are part of what makes the system resilient."
A distinguishing feature of the Australian and New Zealand renewables markets is that the economics now stand on their own. Unlike markets where the investment case has leaned on tax credits or government support, projects here are increasingly cost-competitive against conventional generation, supported by private-sector willingness to contract for clean power to meet corporate sustainability commitments. Subsidised markets have a habit of ending badly when support is withdrawn; a market that does not depend on subsidies to be commercial is likely to prove more durable.
According to the latest projections from the Australian Energy Market Operator, the use of renewable energy will expand drastically between now and 2050, particularly solar and wind power. With two thirds of coal-fired electricity plants due to retire by 2035, the regulator describes renewables as the “least-cost way to supply secure and reliable electricity to consumers”.

Digital, and the water that cools it
Digital infrastructure is the second major theme, with demand running ahead of supply. Boston Consulting Group projects that Australian data centre capacity will roughly double by the end of the decade, from around 1.8GW in 2025 to 4.3GW by 2030, requiring an estimated A$100-120 billion of capital expenditure.10 Westpac suggests that figure could rise to around A$155 billion once the associated renewable build-out is included.11

Australia’s appeal as a regional hub for AI-related infrastructure and data centres rests on a combination of abundant renewable energy across a vast land mass, membership of the Five Eyes intelligence partnership and the security profile that brings a transparent regulatory environment, robust subsea connectivity and available skilled labour.
The constraint increasingly discussed alongside power is water, with cooling demand drawing parliamentary scrutiny. But this is where adjacencies between sectors can be part of the solution. Our own wastewater recycling operation in Sydney draws load off the metropolitan sewerage network and repurposes water that would otherwise be discharged to the ocean, supplying cooling water to data centres and displacing potable supply. The same capability irrigates vineyards in South Australia. Water-cooling systems have significant benefits over conventional air-cooling, reducing energy consumption by around 27%, while also being quieter and taking up less physical space.12
None of these sub-sectors stands entirely alone; the linkages across energy, digital and water and waste are part of what makes the system resilient, and the opportunity set so compelling.
“Buy to build”: Where value is created
What distinguishes the middle market is not only that there are fewer buyers, but that there are more ways to create value once an asset is owned. Many of the businesses we invest in have never been held by institutional capital; they are founder-led or family-owned, well run in a local context but rarely fully professionalised. That leaves room to strengthen management, install appropriate governance and incentive structures, invest in assets that have been short on capital and improve cost and revenue management. Once a business has been professionalised and scaled, it becomes attractive to a wider pool of buyers, including larger funds and strategic acquirers.
Our origination approach falls into three categories: management-team-backed plays, asset-backed aggregation that establishes incumbency in a target sector, and opportunistic situations. Building a position of this kind within a fragmented sector is the foundation for generating returns, and subsequent investments tend to be accretive to the first.
Incumbency does more than improve sourcing. In sectors such as renewables, digital and waste, counterparties increasingly value certainty of execution and long-term operating capability alongside price. As the assets become more operationally complex, our delivery track record can matter as much as the headline bid – a dynamic markedly different from large-cap auctions.
"What distinguishes the middle market is not only that there are fewer buyers, but that there are more ways to create value once an asset is owned."
Atmos Renewables illustrates the asset-led aggregation model. Built from the ground up, it began with a competitive mid-market transaction and then consolidated single assets carrying capital-structure, cost and single-asset risk inefficiencies into one utility-scale platform, before moving into an organic development phase. By August 2025, the platform spanned more than 1.5GW across 18 operational and under-construction wind, solar and storage projects, with a further 5GW under development.
Vertis Energy in distributed energy, is an example of the management-team-backed model. Distributed generation is highly fragmented and smaller in scale, so a capable team able to execute repeatable, modest-sized investments is central to success. We began building exposure in 2019 and have since transformed the capability into a fully integrated platform.
Integrated Waste Services demonstrates vertical integration with purpose. In New South Wales, which produces about a third of Australia’s waste and could exhaust its landfill capacity within the next decade, we started with resource recovery and transfer stations, added greenfield landfill, then acquired collections to secure feedstock, notably construction and demolition waste. Capturing margin along the value chain is part of the rationale; the other part is de-risking, since underwriting the volumes flowing through the gate makes the greenfield landfill more resilient.
CoNEXA brings the water thematic into focus. Water utilities are among the last major infrastructure assets still in public hands in Australia, making them a rare point of entry into an essential service. Their importance is hard to overstate on the driest inhabited continent on earth, where water security is a national concern. An integrated water utility, CoNEXA spans five assets across the eastern states, which collectively recycle around 10 billion litres of water each year, easing pressure on potable supply.
Resilience when it matters
Global allocators often ask how Australian and New Zealand infrastructure performs through challenging macroeconomic environments. The global pandemic and the high-inflation, high-rate cycle that followed presented a serious test, one in which middle-market assets with essential service characteristics demonstrated their pricing power and margin resilience. Australia’s broader economic record supports the point: through the global financial crisis, the pandemic and the energy-price shock that followed the invasion of Ukraine, the economy showed lower GDP volatility than many developed peers.
Most infrastructure assets are, by nature, domestic. A Bass Strait freight network, a regional data centre, a wastewater recycling plant or a waste collections business have little direct exposure to tariffs, global trade flows or currency volatility. In a period when internationally exposed assets carry heightened geopolitical risk, that domestic orientation is a source of stability. Australia’s position as a holder of resources the world needs reinforces it: the country holds among the largest identified lithium and iron ore resource bases globally and meaningful shares of copper, rare earths and other critical minerals, underpinning resource-linked infrastructure demand.13

The role of Australasian infra in a global portfolio
For a global allocator, Australia and New Zealand can play three distinct roles within a diversified infrastructure programme. The first is developed-market exposure underpinned by strong institutions, governance and the rule of law, qualities that make long-dated cashflows dependable. The second is structural growth of a kind that is hard to find in other developed infrastructure markets, with population growth, electrification, digitalisation and resource-linked demand all supporting sustained investment demand. The third is diversification away from the heavily intermediated large-cap segment, where competition and pricing pressure are most acute, toward a fragmented middle market in which an active owner can shape outcomes.
The region also sits at the intersection of several global themes at once: energy transition, resource security, the digital build-out and climate resilience. Those themes are interconnected rather than separate: data centres draw on renewable generation, transmission and water; electrification raises demand for storage and logistics; population growth feeds transport, waste and utilities. An owner who understands the linkages across that system is better placed to find opportunities beyond the most crowded parts of the market, and to build businesses that are more resilient . Australia’s critical-mineral resource base and renewable potential place it at the centre of these trends, while New Zealand’s infrastructure renewal requirements and energy transition create complementary opportunities.
None of this removes the need for selectivity. Infrastructure investing in the region remains operationally demanding. Construction costs, financing conditions and labour availability all bear on delivery. The case rests not on the market being easy, but on its depth, resilience and the breadth of opportunities available to managers able to originate and build rather than simply acquire assets.
"For allocators seeking resilient, long-duration income with genuine growth, that combination is difficult to find elsewhere."
At the frontier, and still here
Our presence in the region began just over three decades ago, around the time when the modern listed infrastructure sector emerged in Australia. We have been present through the privatisations of the mid-1990s to today’s market driven by decarbonisation, digitalisation, transport and water. That longevity has produced deep sector relationships and operating expertise.
The case for Australian and New Zealand middle-market infrastructure rests on more than a favourable macro backdrop. It is a structural argument about a deep, fragmented segment of two of the world’s most stable infrastructure markets where an active, relationship-led owner can both access essential assets and build them into something more valuable. For allocators seeking resilient, long-duration income with genuine growth, that combination is difficult to find elsewhere.
The middle market offers more opportunities to originate, build and create value.
