Knight Frank’s Wealth Report 2026 forecasts Australia’s UHNW population growing 59% to 26,095 by 2031, and the Australian billionaire count growing 77% to 85, the fourth-fastest billionaire growth rate of any major economy.
The Knight Frank Family Office Survey 2026 names data centres and the utility infrastructure powering them as the headline emerging investment theme for the world’s 10,000 family offices.
Gilbert + Tobin’s 25 May 2026 insight confirms GPU clusters are now a distinct infrastructure asset class, financed off long-term take-or-pay contracts, with energy strategy as a hard financing constraint.
The Commonwealth’s Expectations of data centres and AI infrastructure developers, released 23 March 2026, is operating as a de facto gatekeeper. In parallel, the NSW Investment Delivery Authority moved 15 data centre projects worth A$51.9 billion into its priority pipeline four days later on 27 March 2026.
Disclosed Australian-domiciled AI infrastructure capital deployed or committed in the past 18 months exceeds A$60 billion. Direct family office equity into Australian-domiciled operators is conspicuously absent.
What Knight Frank just said about Australia
The 20th edition of The Wealth Report landed on 30 April 2026 with three findings worth holding in view.
Australia is now a top-five global wealth-creation engine. UHNW population is forecast to grow from 16,460 in 2026 to 26,095 by 2031, the fifth-fastest national growth rate worldwide. The Australian billionaire count is forecast to grow 77% over the same period, from 48 to 85, behind only Saudi Arabia, Poland and Sweden. Knight Frank’s own framing: “In a world where wealth is becoming more mobile, Australia stands out for the diversity and durability of its wealth creation story.”
Data centres are the headline allocation theme for family offices. The Knight Frank Family Office Survey 2026, drawing on more than 40 interviews across London, New York, Dubai, Singapore and Hong Kong, identifies digital infrastructure as the leading emerging investment theme. The defining quote, from a family office principal: “We are hugely bought into digital infrastructure, not just data centres, but utility projects that are powering data centres.”
The Active Capital signal backs it up. The Knight Frank Active Capital Survey 2026 reports almost a quarter of CRE investors anticipate investing in infrastructure by the end of 2026, up from 12% currently. Data centres alone saw a 36% year-on-year hike in 2025 investment. The Wealth Report’s energy essay, Power, power everywhere?, lands where Gilbert + Tobin land: dependable energy determines whether a hyperscale data centre can open.
What Gilbert + Tobin just said about financing
Gilbert + Tobin’s 25 May 2026 insight, inside the firm’s Beyond Transition series, codifies what the financing market has been signalling for the past 18 months. Five points to note.
GPU clusters are a distinct infrastructure asset class. Value is migrating from the data centre shell to the compute platform inside it. Financing follows the silicon, not the slab.
Bankability sits in the customer contract. Long-dated take-or-pay arrangements with creditworthy hyperscalers or enterprise AI buyers give a GPU cluster the cashflow profile of traditional infrastructure. The new risk is counterparty concentration. One hyperscaler customer equals single-name credit risk dressed as infrastructure.
Private credit got there first. Commercial banks are warming up. The sponsor mix is broadening from hyperscalers to specialist neoclouds and GPU clouds, as Certified Strategic has tracked in our neocloud market report.
Energy is a financing covenant in everything but name. A project without a credible energy story is becoming uninvestable rather than just expensive.
Australia’s bottleneck is coordination, not capital. Planning frameworks, transmission, energy policy and approvals are the friction. Gilbert + Tobin explicitly call out the Commonwealth’s Expectations of data centres and AI infrastructure developers as a “de facto gatekeeper” for project finance, despite the document having no statutory force.
Federal and state action are converging. Four days after the Commonwealth released its Expectations document, on 27 March 2026, the NSW Investment Delivery Authority moved 15 data centre projects worth A$51.9 billion into its priority pipeline, part of a wider inaugural round of 31 endorsed projects worth A$86.3 billion administered by the NSW Premier’s Department.
Where the two documents lock together
Knight Frank describe the capital side: who has the money, what they want to buy, how they are operationalising the buying. Gilbert + Tobin describe the structuring side: how the deal gets put together, where the bankability sits, which regulatory document acts as the screen.
Together they map a complete trade. An Australian GPU cluster financed by private credit, co-invested by a family office syndicate, with an integrated energy strategy underwritten as part of the credit case, screened against the Commonwealth Expectations document, and contracted off a take-or-pay arrangement with a hyperscaler or enterprise AI buyer.
This is no longer hypothetical. It is the operating structure of every major Australian AI infrastructure deal closed in the last 12 months.
The deal flow that already exists
The capital is arriving at industrial scale. Nine transactions over the past 18 months mark the new floor.
Transaction | Size | Date | Capital source |
Blackstone and CPP acquire AirTrunk | A$24 billion | Sep 2024 | Global PE and Canadian pension |
Firmus Project Southgate debt facility | US$10 billion | Apr 2026 | Blackstone, Coatue |
IREN secures Microsoft AI cloud contract | US$9.7 billion | Nov 2025 | Take-or-pay enterprise contract |
HMC Capital lists DigiCo Infrastructure REIT (ASX:DGT) | A$4.3 billion EV | Dec 2024 | Public markets |
CDC Data Centres refinancing | A$2.7 billion + A$308m USPP | 2026 | Syndicated bank and institutional |
AustralianSuper into Vantage EMEA | A$2.5 billion | Dec 2025 | Australian superannuation |
NEXTDC capital plan | A$2.2 billion | Apr–May 2026 | Public markets + Quebec sovereign |
SharonAI GPU-backed facility | US$500 million | Q1 2026 | Specialist private credit |
Aware Super into Vantage APAC | US$300 million | Jan 2026 | Australian superannuation |
Source: Certified Strategic Editorial, primary company disclosures, May 2026.
The pattern fits Gilbert + Tobin’s thesis exactly. Take-or-pay sits at the centre of the credit case in Firmus, IREN, NEXTDC and CDC. Sovereign and pension capital is showing up as long-dated equity through Aware Super, AustralianSuper, La Caisse (Quebec) and CPP (Canada). Private credit is filling the gap where traditional senior debt is not yet committee-ready.
What is absent from the table is direct family office equity into Australian-domiciled AI infrastructure operators. The Knight Frank Family Office Survey says the appetite is there. The first announced trade will reset the price of access for everyone behind it.
The information gap
The binding constraint in Australian AI infrastructure is no longer capital or structuring expertise. Both are accumulating fast. The constraint is informational.
A family office principal in Singapore, Dubai or London who wants to co-invest in Australian AI infrastructure has no consolidated view of:
• Which operators have credible contracted revenue books
• Which sites have credible energy plans
• Which projects are aligned with the Expectations document
• Which sponsors have the consenting pathways to deliver
The brokers do not have it. The law firms have fragments from their own client books. The hyperscalers will not share it. The federal and state agencies are not equipped to publish it. The big-four research desks are publishing thematic essays, not pipeline-level intelligence. And no autonomous intelligence platform has, until now, been built specifically for this category in Australia.
Three wealth vectors for HNWI capital
Place the Knight Frank forecast alongside the disclosed deal flow and three vectors emerge for HNWI capital entering Australian AI infrastructure.
1. Direct equity in operators. Neoclouds, GPU clouds, sovereign AI plays. High return, high information asymmetry, narrow window. Family office appetite confirmed by Knight Frank. Structuring capacity confirmed by Gilbert + Tobin. Inbound flow has not yet matched the demand profile.
2. The energy and utility layer. The Knight Frank family office quote almost verbatim, and the segment closest to a textbook infrastructure-asset profile for a passive allocator. Australian family office capital already has a track record here through Cannon-Brookes and Forrest into Sun Cable and Squadron Energy. The synergy with AI infrastructure is structural: the energy contract is now embedded inside the GPU cluster credit case.
3. The intelligence and information layer. The least obvious of the three, and the highest-leverage. It is the diligence apparatus, the pipeline radar, the operator screening tool and the policy-watch desk in one asset. It is also a non-obvious moat. The operators trust the intelligence layer with their data because the publication has built credibility independently of any single capital provider. That credibility is hard to bootstrap. It is easier to acquire one already operating. As we set out in our analysis of Australia’s 12-to-18-month window to capture its share of the AI infrastructure boom, capital allocators are now the new readers.
What to watch over the next six months
Four catalysts will tell us whether the Knight Frank and Gilbert + Tobin convergence becomes the operating template for the category.
The next NSW IDA endorsement tranche. The 15 data centre projects endorsed on 27 March 2026 covered A$51.9 billion. The next NSW IDA disclosure cycle will signal which operators move up the priority list, and whether other states establish equivalent fast-track bodies.
The AEMC final rule on grid connections. Consultation closed on 7 May 2026. The final rule will define what the Commonwealth’s energy expectation looks like at the grid-connection interface. Worth reading alongside our coverage of the NSW data centre consultation paper.
The Firmus ASX listing. A successful Australian IPO at scale would be the first listed pure-play GPU-backed AI infrastructure vehicle in this market, and a public benchmark for HNWI allocators who will not write a private credit cheque.
The first named family office trade. The Knight Frank Survey signals the appetite. The first announced direct equity round into a named neocloud or GPU cloud operator will reset the price of co-investment access for everyone behind it.
