There is a particular quality to infrastructural reckoning — the moment when a network built to serve one era discovers that the era is ending. It does not arrive loudly. Revenues hold, contracts renew, tonnages tick upward in a good year. But underneath the operational surface, the ground is shifting, and those who manage great rail systems must reckon with a question that no quarterly report can fully answer: what does this network become when the commodity that created it no longer commands the same world?

For Aurizon Holdings — the Brisbane-headquartered freight rail company that descends from Queensland Rail’s privatised freight operations, floated on the Australian Securities Exchange in November 2010 and rebranded in 2012 — that question has arrived in earnest. Formerly named QR National Limited, Aurizon was in 2015 the world’s largest rail transporter of coal from mine to port. That origin defines both the company’s extraordinary infrastructure inheritance and its current strategic predicament. Aurizon carries around half of Australia’s exported coal, and its share price has at times mirrored moves in that of the fossil fuel itself. When coal does well, Aurizon does well. When coal contracts, the reverberations move through every corridor of the company’s finances.

The energy transition is not an abstraction for Aurizon. It is a structural force slowly reshaping the demand curves that underpin the company’s largest revenue stream, operating across a 2,670-kilometre rail network in Queensland that exists for one primary purpose: moving coal from the mines of the Bowen Basin to the coast. Understanding what that transition means — in timing, in scale, in strategic response — is among the more important questions in Australian industrial history right now.

aurizon.queensland represents the permanent onchain civic address through which Aurizon’s identity as Queensland’s foundational freight operator is anchored in the digital record — a recognition that the company’s history, its infrastructure, and its transition are matters of lasting public significance, not merely commercial footnotes.

THE COAL DEPENDENCY IN NUMBERS.

To understand the energy transition’s implications for Aurizon, one must first understand the depth of the coal relationship. Aurizon’s Coal business transports coal from mines in the Newlands, Goonyella, Blackwater, Moura and West Moreton systems in Queensland and the Hunter Valley and Illawarra coal systems in New South Wales, to domestic customers and coal export terminals. Coal hauled is split approximately evenly between metallurgical coal and thermal coal, with demand linked to Asian steel production and energy generation, respectively.

In the financial year ended June 2025 (FY2025), Central Queensland Coal Network volumes were 133.7 million tonnes, while total coal revenue increased by $34 million, or 2 per cent, to $1.777 billion. That figure alone — $1.777 billion from coal revenue — illuminates the dependency with precision. Coal haulage from mine to port contributes roughly a third of Aurizon’s operating income, while the non-coal bulk segment contributes less than 15 per cent of earnings and undertakes the rail haulage of agricultural, mining, and industrial products. The regulated Network business — essentially the infrastructure business of managing the Central Queensland Coal Network — contributes approximately half of earnings through the company’s 2,670-kilometre coal rail network held under a 99-year lease from the Queensland government.

The picture that emerges is a company with two coal-adjacent businesses — the direct haulage operation and the regulated network — together comprising the great majority of its earnings base. Non-coal activities, though growing, remain structurally subordinate. This is not a flaw in Aurizon’s management; it is the inheritance of an infrastructure company built expressly for the coal economy of Queensland.

THE GLOBAL SIGNAL: DEMAND, DECLINE, AND DIFFERENTIATED FUTURES.

The energy transition’s impact on coal is not uniform. Thermal coal — used for electricity generation — faces a more immediate and more severe demand trajectory than metallurgical coal, which is used in steelmaking and for which no proven, commercially scaled alternative yet exists at the required volume.

The Australian Department of Industry, Science and Resources projects thermal coal export earnings to decline from A$36 billion in FY2023–24 to about A$21 billion by FY2028–29, in real terms, as coal prices continue to decline. That is a fall of more than 40 per cent in export earnings within five years. For the first time, the government’s own Resources and Energy Quarterly has forecast that thermal export volumes will decline during the five-year outlook period, down 14 million tonnes in FY2029–30 on expected FY2024–25 levels, with government projections showing Australian thermal coal exports peaking and beginning to decline through to 2030.

The primary markets tell a consistent story. Thermal coal demand in Japan, South Korea and Taiwan — which collectively account for the largest share of Australian thermal coal exports — is expected to continue to decline. China and India both increased domestic coal production in 2024, with China and India expected to decrease reliance on imports.

For metallurgical coal, the trajectory is slower but pointed in the same direction. The International Energy Agency has stated that overall global met coal demand is set to decline by 53 million tonnes between 2025 and 2030, “underscoring the gradual transition in steelmaking technologies and regional economic dynamics.” Global metallurgical coal demand is expected to fall to 2030 as non-coal-based steel production — including electric arc furnace technology — gains pace. Australia’s exports also face the reality that India is diversifying met coal imports away from Australia, while China lowers steel production.

Projections indicate that global coal demand is likely to plateau around 2024 and then enter a period of gradual decline, driven by both environmental policies and the increasing cost-competitiveness of renewables. This is not prediction; it is the convergence of multiple independent institutional forecasts — the IEA, the Australian federal government’s own quarterly resources analysis, and a range of market analysts — pointing in the same direction.

"Global coal use will start declining by 2030 under its Current Policies scenario, or even earlier if the Paris Agreement goal to limit global heating to 1.5°C is taken seriously."

This framing, drawn from the IEA’s World Energy Outlook 2025 as reported by the Institute for Energy Economics and Financial Analysis, captures the essential asymmetry facing Aurizon: the timing is uncertain, but the direction is not.

OPERATIONAL VOLATILITY: WEATHER, MINES, AND THE NEAR TERM.

Before the long arc of structural decline, Aurizon has had to navigate a more immediate layer of operational turbulence. In FY2023, coal haulage volumes — a roughly even mix of thermal and coking coal from central Queensland and New South Wales mines — decreased 5 per cent to 185 million tonnes, with the EBITDA of the coal division falling 16 per cent year-on-year to $455 million. Aurizon attributed the coal slump to “the impact of prolonged wet weather, a major third-party derailment and mine-specific production issues.”

In FY2024, Aurizon expected to increase coal haulage volumes after missing its FY2023–24 target, having hauled 189 million tonnes of coal — up from 185 million tonnes in the weather-affected prior year but below the 194 million tonnes achieved in FY2021–22. The pattern is one of persistent underperformance against contracted capacity, shaped by the particular vulnerability of Queensland’s coal rail corridors to extreme weather. The Bowen Basin sits in a region where La Niña weather events bring heavy rainfall that floods rail formations, washes out tracks, and closes corridors for weeks at a time. Queensland floods in early 2024 caused widespread network closures, affecting Aurizon’s ability to transport commodities.

Lower-than-anticipated network volumes on the Central Queensland Coal Network in FY2025 led to a deferral of $50 million in earnings to FY2027 due to revenue under-recovery under the regulated framework. This is the institutional mechanism of the regulated network at work: when volumes fall below the regulatory forecast, Aurizon Network cannot fully recover its allowed revenue in the period, and the shortfall is deferred — a feature of the regulatory architecture that provides some protection but also creates financial timing risks.

In August 2025, Aurizon announced its FY2025 full-year results, showing revenue of $3.952 billion — a 3 per cent increase — while underlying EBITDA was $1.576 billion, a 3 per cent decrease, with underlying net profit after tax down 14 per cent to $348 million. The revenue line grew; the earnings did not. The gap between them reflects the cost pressures — labour escalation, maintenance, the absorption of new containerised freight operations still ramping to profitability — that accompany the company’s transition effort.

THE PIVOT: NON-COAL GROWTH AND THE ACQUISITION STRATEGY.

Aurizon’s strategic response to coal’s long-term trajectory has been deliberate and substantial. The clearest single expression of that response came in October 2021, when Aurizon Holdings signed an agreement with Macquarie Asset Management to acquire One Rail Australia for $2.35 billion. One Rail Australia comprised bulk rail haulage and general freight assets in South Australia and the Northern Territory, the 2,200-kilometre Tarcoola-to-Darwin railway line, and a haulage business in New South Wales and Queensland. The sale was completed on 29 July 2022, and Aurizon took over One Rail Australia’s South Australian, Northern Territory and interstate operations under the brand “Aurizon Bulk Central.”

The strategic logic was explicit: the One Rail acquisition delivered “a step change for Aurizon Bulk as a new entrant in the SA and NT region, and supports the ongoing growth of non-coal revenue in the Aurizon portfolio.” The acquisition included the 2,200-kilometre Tarcoola-to-Darwin railway line, “connecting regions rich in resources and agricultural commodities with Darwin, the closest port to Asia,” and was described as delivering “scope and scale with new customers, new regions and greater exposure to new economy commodities such as copper, manganese and rare earths.”

The containerised freight ambition followed a different logic — not bulk commodity haulage but general freight, the movement of consumer goods, food, clothing and industrial products across Australia’s continent-wide distances. In February 2023, Aurizon inaugurated two Melbourne–Perth containerised freight services and in September 2023 a weekly return container service on the Melbourne–Sydney–Brisbane corridor in collaboration with its customer, Team Global Express. The ramp-up of national linehaul services for containerised freight was completed in May 2024, with these services now reaching all major capital city markets and import and export terminals.

The growth in non-coal revenue has been measurable. As Aurizon reported for FY2023, non-coal revenue had by that point come to comprise 45 per cent of non-network revenue — up 11 percentage points compared with FY2022. A key stated objective is to reduce reliance on coal haulage, aiming to bring it below 20 per cent of above-rail revenue by 2030. That is a meaningful structural ambition — to move from a business where coal dominates haulage revenue to one where it is a minority contributor, within a decade.

More recently, the company secured a substantial AUD 1.5 billion deal with BHP Group for copper logistics in South Australia. Aurizon is actively focusing on “new-economy commodities” in central Australia, including copper, magnetite, phosphate, and rare earths. These are the minerals of the energy transition itself — the inputs to batteries, solar panels, and electric motors. There is an irony worth noting: the force that is contracting coal demand is simultaneously creating the commodity demand that Aurizon hopes will replace it.

THE DECARBONISATION CHALLENGE: A FLEET OF 600 DIESEL LOCOMOTIVES.

Aurizon’s energy transition challenge is not only about what it hauls. It is also about how it hauls it. Aurizon operates a fleet of more than 600 diesel locomotives and carries 250 million tonnes of freight a year across Australia. Rail freight emissions from Australia’s heavy haul freight industry account for more than 4 million tonnes of carbon emissions, or 0.8 per cent of Australia’s total greenhouse gas emissions. That number, modest in aggregate national terms, is nonetheless a material liability as emissions reporting requirements tighten and as customers increasingly need to demonstrate decarbonised supply chains.

Aurizon has set an ambitious goal to achieve net-zero operational emissions by 2050, as outlined in its 2024 Sustainability Report. The pathway to that goal runs through technology that does not yet exist at commercial scale for heavy haul rail in Australia. Aurizon has developed a three-pronged approach.

The project is the second of Aurizon’s three-pronged strategy to develop a zero-emission fleet. Aurizon started work on the first part, Australia’s first battery-electric locomotive, built by Progress Rail, in May 2023. The prototype is expected to start line trials on routes of up to 400 kilometres in late 2025.

Aurizon has also secured a $9.4 million grant from the Australian Renewable Energy Agency (ARENA) to develop, test and trial a battery-electric tender to be used in conjunction with a modified locomotive. The tender — essentially a large battery-pack on wheels — will couple with the modified locomotive to operate as a hybrid unit using both diesel and battery-electric power sources, with the tender’s battery also harnessing regenerative energy captured as the train travels down grades and brakes. When coupled with the battery-electric locomotive, this combination aims to extend the future range for freight hauls up to 850 kilometres, with trials expected to commence in early 2026.

The third part of the strategy involves Aurizon working with Anglo American on a feasibility study to introduce hydrogen-powered traction for bulk freight, with the study concluding that a hydrogen-electric tender was the preferred configuration given the lack of space on the locomotive to store the required amount of hydrogen fuel.

Locomotives typically have an asset life of 20 to 30 years, so replacing the diesel engine with batteries and recycling the remainder of the locomotive is less expensive, more environmentally sound, and consistent with circular economy principles. The strategic elegance of this approach lies in its avoidance of full fleet replacement — a capital commitment that would be prohibitive — in favour of staged retrofitting, technology hybridisation, and route-by-route optimisation.

THE INVESTOR SIGNAL AND THE SHARE PRICE QUESTION.

Financial markets are forward-looking, and Aurizon’s share price has been one of the more candid expressions of the market’s uncertainty about coal’s long-term future. Having tumbled approximately 40 per cent over the five years to late 2024, it appears investors have lost confidence in Australia’s largest rail freight operator, with the share price dipping 8 per cent despite the posting of strong results in August 2024 amid ongoing worries about the future of coal.

Market analysis attributes the discount to fair value as driven by uncertainties around long-term coal demand and concerns about capital allocation. This is the structural tension in Aurizon’s investment case: the coal business remains highly cash-generative in the near term, the regulated network business provides stable regulated returns, but the long-term trajectory of the primary commodity creates a persistent overhang on the stock’s valuation.

Morningstar has emphasised the importance of investment in non-coal businesses to diversify away from thermal coal and maintain the support of Western lenders. The lending dimension matters here — Western institutional lenders increasingly apply ESG criteria to their credit decisions, and a company with an outsized coal dependency may face higher funding costs or reduced access to certain debt markets over time. In addition to diversifying away from coal, Aurizon has broadened its lending base by adding several Asian banks. That decision reflects a pragmatic understanding that the capital market landscape is not monolithic: Asian financial institutions retain a different risk calculus regarding coal exposure than many European and American peers.

Simon Conn, senior portfolio manager at investment group IML, said that while it was early days, Aurizon’s strategy for diversifying away from coal appeared to be working, adding that “the nature of these assets is that you have to spend capital, build things… and that takes time.” That observation — patient, structural — captures the essential reality of infrastructure transition. It does not happen in a single financial year. It is measured in asset lives, contract cycles, and the slow accumulation of new revenue streams.

THE REGULATORY DIMENSION: A NETWORK BUILT FOR COAL, GOVERNED FOR COAL.

There is a further structural layer to Aurizon’s transition challenge: the Central Queensland Coal Network, the 2,670-kilometre regulated network at the heart of the company’s infrastructure earnings, was designed, built, and governe expressly for coal. Its access regime — managed by the Queensland Competition Authority — sets reference tariffs, regulates utilisation, and manages the complex commercial relationships between Aurizon Network and the mining companies that use the track.

Lower-than-anticipated network volumes on the CQCN in FY2025 led to revenue under-recovery under the regulatory framework, deferring $50 million in earnings to FY2027. The current Access Undertaking, known as UT5, governs this relationship; since mid-2024, the Network and the Rail Working Group have been meeting to discuss a Draft Amending Access Undertaking to apply once UT5 ends on 30 June 2027, with a submission targeted for the December 2025 quarter.

The regulatory architecture creates both protection and constraint. It provides certainty of revenue recovery through the take-or-pay mechanisms that require mining companies to pay for contracted capacity whether or not they actually use it. But it is a system premised on coal volumes remaining within a particular range. As volumes structurally decline toward the end of the decade, the regulatory compact will face its own renegotiation — a question of how the enormous sunk infrastructure costs of the CQCN should be allocated across a smaller and smaller customer base.

A declining coal market could accelerate mine closures in Australia, with the government’s own analysis stating that “a prolonged decline in prices may result in some older and smaller mine closures being brought forward.” Fewer mines means fewer tonnes means a more concentrated customer base bearing the fixed costs of infrastructure that was sized for a larger system. This dynamic — well understood in the economics of regulated monopoly infrastructure — will be among the defining regulatory questions for the Queensland Competition Authority through the 2030s.

WHAT COAL DECLINE ACTUALLY MEANS: A MEASURED RECKONING.

It is worth being precise about what the energy transition does and does not mean for Aurizon in practical terms across the next decade.

It does not mean the sudden cessation of coal haulage. In FY2024, Aurizon hauled 189 million metric tonnes of coal out of a contracted capacity of 230 million, reflecting an 82 per cent utilisation rate. Morningstar has forecast coal haulage volumes to increase to 211 million metric tonnes by 2029 as contracted volumes rise and mines recover from weather disruptions. The short to medium term remains a period of substantial coal operations.

It does not mean that metallurgical coal vanishes from Aurizon’s books in the 2030s. The steel sector’s decarbonisation is real but gradual, and Queensland’s premium coking coals — particularly those from the Bowen Basin — retain demand from Asian markets building out infrastructure and manufacturing capacity. The government’s analysis projects Australian met coal export volumes will peak in FY2027–28, before declining, though the trajectory remains contested between different analytical frameworks.

What it does mean is a structural narrowing of the coal market’s contribution to Aurizon’s total earnings over a ten-to-fifteen-year horizon. Aurizon faces significant threats from the ongoing global energy transition, which could reduce demand for coal haulage, with a continued shift towards renewables possibly seeing coal volumes decline by 3 to 5 per cent annually in the coming years. Applied to a base of 192 million tonnes, a sustained annual decline of that magnitude would subtract tens of millions of tonnes from the haulage book within a decade.

The company’s response — diversifying into bulk minerals aligned with the energy transition, expanding containerised freight nationally, investing in the technology to decarbonise its own locomotive fleet, and extending its geographic reach into central and northern Australia — reflects an organisation that has absorbed this reality and is acting on it, even if the pace and scale of transformation remain sources of legitimate investor uncertainty.

PERMANENCE IN TRANSITION: INFRASTRUCTURE AS CIVIC IDENTITY.

There is something worth holding onto in all of this: the infrastructure itself does not disappear when the commodity changes. The rail formations of the Bowen Basin, the gauge-specific track through the Goonyella system, the port terminals at Hay Point and Dalrymple Bay — these physical assets have a permanence that outlasts any particular commodity cycle. The question is not whether they continue to exist, but what purpose they serve and for whose benefit.

Aurizon carries the institutional weight of Queensland’s industrial history. It emerged from a state-owned railway that built Queensland’s resource economy from the ground up, and it continues to operate the arteries through which the state’s export wealth flows. That history does not dissolve under the pressure of energy transition; it transforms. The company that once moved only coal now moves grain and iron ore, copper and containers, mineral sands and agricultural inputs across a continent-spanning network. The coal dependency that once appeared to be its permanent identity is now one dimension of a larger, more varied business.

Understanding that transition, tracking its progress, and assessing its implications for Queensland’s communities, its workers, its regulatory architecture, and its place in the global commodity economy — these are questions with genuine civic weight. They belong to the public record in the same way that the infrastructure itself belongs, in a fundamental sense, to the public through whose land it runs and whose economic life it shapes. The namespace aurizon.queensland marks that civic permanence — not the commercial fortunes of any particular year, but the enduring fact of a great infrastructure system navigating the most consequential industrial transition of the century, anchored in the land and identity of Queensland.
