The Economics of Tasmanian Wind

 

Why new projects face a wall

Tasmania’s energy debate still assumes that wind farms are profitable and Marinus will unlock a wave of new renewable investment. But the only audited window we have into the real economics of Tasmanian wind — the accounts of Woolnorth Wind Farms (WWF) — tells a very different story.

WWF supplies around 10% of Tasmania’s electricity, with 308 MW of generation across Bluff Point, Studland Bay and Musselroe Bay. It is also the only operator that files full financials with ASIC. Those accounts reveal the structural truth that now defines the future of Tasmanian renewables: Tasmania’s oldest wind farms are only profitable because Hydro Tasmania subsidises them — especially via Large Scale Generation Certificate (LGC) guarantees. Strip out those supports and WWF is loss‑making every year, even with its current low level of debt.

This is the starting point for understanding why new wind projects — the very projects Marinus depends on — face a wall.

ASH attempts to correct the record

 

ASH’s response to Four Corners (it appeared in a Facebook post which is pasted below) presents itself as a factual correction. In reality, it is a carefully constructed piece of misdirection that avoids the central financial facts, reframes definitions to obscure economic reality, and omits the single most important issue facing the company - the looming 2027 redemption cliff. Once the structure is laid out clearly, the Facebook post collapses.

Heyfield ASH to Ashes?

PART 3: HEYFIELD -ASH TO ASHES?

The 2027 Redemption Cliff

By the time the 2025 financial statements were signed, the future of Heyfield ASH Holdings (HAH) was no longer a question of operational performance or market conditions. It had become a question of solvency. The business had reached the point where the structure created in 2017, and reinforced through the WJS years, could no longer be sustained by accounting treatments, inventory movements, or government grants. The numbers had converged on a single, immovable fact: in 2027, HAH must repay $33 million to the Victorian Government, and there is no internal source of funds to do so.

The redemption of the cumulative preference shares is not a technicality. It is the moment the entire structure is tested. And the closer we get to that date, the clearer it becomes that the structure cannot withstand the test.

Heyfield ASH The WJS Years

 

This is the second part of a three‑part series on Heyfield–ASH: A Case Study in Public Risk and Private Control

PART 2:THE WJS YEARS

When the private partners behind Heyfield ASH Holdings (HAH) purchased the Western Junction Sawmill (WJS) in northern Tasmania in October 2021, the move was presented as a pragmatic response to Victoria’s decision to shut down its native forest industry. The public explanation was simple: if Heyfield could no longer source logs locally, it needed a new supply chain. But the financial statements tell a more complicated story — one in which the Tasmanian acquisition did not merely secure log supply but reshaped the entire economic structure of the business. What emerged was not a conventional supplier relationship but a closed‑loop related‑party ecosystem in which HAH became the financier, WJS became the beneficiary, and Victorian taxpayers became the silent underwriters of a private Tasmanian enterprise.

To understand the WJS years, you have to look past the public narrative and follow the money. Once you do, the pattern becomes impossible to ignore.

Heyfield ASH The Beginning

 

Heyfield–ASH: A Case Study in Public Risk and Private Control

This three‑part series traces how a Victorian Government rescue of the Heyfield mill in 2017 created a financial structure that shifted risk onto the public while consolidating control in the hands of a private group; how that structure evolved into a closed related‑party ecosystem once the same private partners acquired the Western Junction Sawmill in Tasmania; and how, by 2027, the entire model now converges on a solvency crisis that the business cannot meet without further public intervention. Across the narrative, a single pattern emerges with clarity: public money flows in, private benefit flows out, and the financial architecture built at the beginning now determines the fate of both the Victorian mill and the Tasmanian native forest supply chain that depends on it. What follows is not simply a corporate history — it is a case study in how public capital can be captured, redirected, and ultimately exhausted in the service of a private arrangement that was never commercially sustainable.

PART 1: THE BEGINNING

How the related‑party structure was built from Day 1

The story of Heyfield ASH Holdings (HAH) does not begin with a struggling sawmill in Gippsland, nor with the closure of Victoria’s native forest industry, nor even with the later Tasmanian supply chain. It begins in September 2017, in the 24 hours before the takeover of Australian Sustainable Hardwoods (ASH), when a series of decisions were made that set the tone for everything that followed. Those decisions reveal a pattern that would later repeat itself: value flowing out to private interests, risk flowing onto the public balance sheet, and a corporate structure designed from the outset to favour the private partners who would eventually control both sides of the supply chain.

To understand the present, you have to understand the beginning. And the beginning is not pretty.

The Heyfield ASH story

This note traces an extraordinary eight‑year story, part of 4 Corners' report Timber Turmoil on 22nd June 2026 (see also ABC on-line report here): how private interests gained control of Australia’s largest hardwood operation with just $600 of capital at risk, and how the Victorian Government contributed more than $130 million to bankroll a privately controlled structure — including the purchase and ongoing operation of a major sawmill in northern Tasmania. The full analysis, including all financial data is available here

A more accessible narrative form of the tale can be found in a short 3-part series.

Part 1 HAH: The Beginning focusses on the purchase of the Australian Sustainable Hardwoods (ASH) business in 2017.

Part 2 HAH: The WJS Years describes the operations of ASH and the purchase of Western Junction Sawmill (WJS) in 2021

Part 3 HAH: ASH to Ashes looks at the looming cash flow crisis as redemption day for much of the Government’s  risk capital fast approaches.

STT: Another year of deceptive profits and economic unviability

 

Sustainable Timber Tasmania's (STT) 24/25 Annual Report attempts to project an image of strategic progress and financial health, proudly declaring "eight years of consecutive profitable results." However, a rigorous, critical examination of the financial statements, viewed through the lens of industry realities and basic economic principles, reveals a far harsher truth: STT's reported profitability is an accounting construct, propped up by non-cash revaluations and heavily reliant on a substantial government grant for unavoidable public land management duties,  and crucially, benefits from the undisclosed, massive subsidy of free access to public land and its timber resource. This deceptive facade of success not only masks a core operation that is economically unviable but also obscures the ongoing accrual of significant, unquantified societal and environmental liabilities that would largely cease if native forest logging operations were to stop.
