Trevor Hansen has been driving refrigerated semi-trailers onto the Bass Strait ferry since 1998 — the same year the ship he still boards, Spirit of Tasmania II, first entered service. Most weeks he loads King Island cheese and Tasmanian salmon for the overnight run to Geelong, because for an island state with no bridge to the mainland, that ferry deck is the road. Twenty-eight years on, Hansen is still driving onto the same ageing ship. A few kilometres away, in the port of Hobart, two brand-new vessels sit fitting out at the wharf — ferries that cost $850 million (approx.) to build, handed over to their state-government owner more than a year ago, but still not licensed to carry a single paying passenger. Tasmania paid for its ferry replacement. It has not yet received it.
That gap, between money spent and service delivered, is the story of the Spirit of Tasmania fleet renewal — one of the largest infrastructure projects a Tasmanian government has run in a generation. It began as an uncontroversial, arguably overdue decision to replace two ships nearing thirty years old. It has become a case study in how a government can order the ship without being ready for it to arrive.
What the government did
TT-Line Company Pty Ltd, the Tasmanian Government-owned corporation that runs the Bass Strait car-and-freight ferry service, announced in December 2017 that it would replace its ageing Spirit of Tasmania I and II with two larger vessels. A contract was signed in January 2018 with German builder Flensburger Schiffbau-Gesellschaft, targeting first delivery in 2021. That contract collapsed in February 2020 and TT-Line pivoted to Finland's Rauma Marine Constructions; the Rauma deal itself was cancelled months later, in July 2020, amid COVID-19 uncertainty, before being re-signed in April 2021 at a combined contract price of around $850 million (approx.) for both ships — Spirit of Tasmania IV and V, each able to carry roughly 1,800 passengers and more than 4,000 lane-metres of vehicles (approx.), noticeably more than the ships they replace.
The new ships needed a new home. The existing Devonport terminal, built for the smaller 1998-era ferries, could not berth vessels of this size, so TT-Line and the Tasmanian Government committed in 2020 to a redeveloped Devonport terminal and berth, initially costed at around $90 million. That single number — a wharf estimated at $90 million to serve ships that alone would cost $850 million — is where the sequencing problem defining this topic begins: the government locked in delivery dates for two enormous, custom-built ships years before the far more locally-controlled task of designing, approving and building the shore-side infrastructure to receive them was secured.
The strongest case
The old ships genuinely needed replacing
Put the decision to renew the fleet at its strongest, because the underlying need was real and not partisan. Spirit of Tasmania I and II entered service in 1998 and by the late 2010s were approaching the end of their economical operating life, carrying the bulk of Tasmania's interstate freight task and hundreds of thousands of tourists a year across one of the more exposed stretches of water in southern Australia. An island state's only vehicle-carrying sea link functions closer to critical road infrastructure than to a discretionary transport service; when it falters, supermarket shelves, export deadlines for perishable produce and the tourism season all feel it within days. Larger, more efficient replacement vessels, an idea supported under both Labor and Liberal governments since it was first floated, were a defensible long-term investment in the state's only fixed sea corridor to the mainland.
Some of what went wrong afterwards was also not entirely of Tasmania's making. The original German shipbuilder contract collapsed for commercial reasons unrelated to the state; the pivot to Finland then ran into a global pandemic that shut shipyards and disrupted supply chains worldwide, followed by Russia's 2022 invasion of Ukraine, which pushed European steel and energy costs sharply higher mid-build. A government locking in a fixed-price shipbuilding contract in April 2021 could not have modelled a European land war into its costings, and the resulting pressure on the vessels' own price was a comparatively contained part of the eventual blowout.
The evidence
What is harder to attribute to global shocks is the terminal. Tasmania's Auditor-General, parliamentary committees and TT-Line's own board have placed detailed, dated figures on the record, and together they show a project whose vessel costs grew but whose shore infrastructure costs exploded. The Devonport berth redevelopment, budgeted at $90 million in 2020, had been revised to around $493–495 million (approx.) by 2024 — a more than five-fold increase, and the single largest component of the overall blowout. In September 2025 it also emerged that TT-Line had supplied its own wharf designers with incorrect vessel specifications back in 2023, requiring a further $9 million (approx.) in fender and hull-strengthening work once the error came to light. Tasmania's Parliamentary Standing Committee of Public Accounts, running a continuing inquiry into "TT-Line's Spirits Project", has since taken sworn evidence putting the total cost of the vessel-replacement program at around $717 million (approx.) above the original business case — a figure TT-Line's own chairman confirmed to the committee in 2025.
The delivery timeline tells the same story from a different angle. Spirit IV completed sea trials in June 2024 and was formally handed over to TT-Line in September 2024 — with the Devonport berth still years from completion. Rather than sail to an unfinished terminal, the ship was sent to the Port of Leith in Scotland for storage from November 2024, at a cost to Tasmanian taxpayers of around $47,000 a week (approx.), while TT-Line fielded around fourteen enquiries from parties interested in chartering the idle vessel, including one lease offer reportedly worth $20–30 million (approx.) over twelve months. That offer was not taken up, and the ship instead sailed home, arriving in Hobart in August 2025 for final fitting-out — the best part of a year after Australia had already paid for it in full.
The fallout
The scale of the blowout claimed a run of senior figures. TT-Line chairman Michael Grainger resigned on 14 August 2024 after the government said its relationship with him had become "untenable"; interim chair Damian Bugg took over the next day. Chief executive Bernard Dwyer, who had led TT-Line for fourteen years and overseen the vessel build from the start, resigned on 7 September 2024, days after a Public Accounts Committee hearing examined why the vessel contract alone had grown by $81.6 million (approx.) above its $850 million base price; chief financial officer Kym Sayers took over as acting chief executive from November 2024. Infrastructure Minister Michael Ferguson resigned that portfolio on 26 August 2024, and then resigned from Cabinet altogether on 14 October 2024, ahead of an expected no-confidence motion in Parliament, while remaining the Liberal member for Bass.
The financial fallout has outlasted the personnel changes. In August 2025, Tasmania's Auditor-General, Martin Thompson, formed the opinion that TT-Line was insolvent and reported the board's position to the Australian Securities and Investments Commission; his November 2025 report to Parliament reiterated that the company's ability to service its debts beyond August 2026 was in serious doubt, a conclusion the board disputed on the basis of its own external advice. The Tasmanian Government has since stepped in repeatedly: a $75 million (approx.) equity injection in its November 2025 budget update, a $400 million (approx.) increase to TT-Line's government-guaranteed borrowing capacity approved during the 2025 state election campaign, and a further $506 million equity injection over four years — $200 million (approx.) of it in the first year alone — confirmed in the 2026-27 Budget handed down in May 2026 to cover past capital cost overruns.
Tasmania ordered two ferries, and in effect built a wharf worth more than five times its own original estimate to receive them.
The critique
Strip away the individual resignations and the critique is about sequencing, not any single villain. A government-owned corporation and its shareholding ministers signed a fixed, multi-year shipbuilding contract for two vessels before the far more locally-controlled task of designing, approving and building the terminal to receive them was anywhere near secured. Shipbuilding risk — currency movements, a war in Europe, a change of shipyard — is genuinely hard for a state government to manage. Wharf-building risk, on a project entirely within Tasmania's own jurisdiction, using its own port authority and its own contractors, is not. That the terminal, not the ships, produced the larger share of the $717 million (approx.) overrun points squarely at planning and project-management failures inside TT-Line and the departments overseeing it, not at forces beyond Tasmania's control.
The 2023 specification error — TT-Line giving its own wharf designers the wrong vessel dimensions, not discovered until 2025 — is a small dollar figure next to the headline blowouts, but it is the clearest single piece of evidence that basic project coordination broke down between the people building the ships and the people building the berth for them. It should not have been possible for the client on both sides of the same project to be working from different numbers.
The Leith storage episode compounds the sequencing failure with a commercial one. Having paid in full for a ship it could not yet use, TT-Line then held it empty at a cost of roughly $47,000 a week while declining a lease offer reportedly worth $20–30 million (approx.) over twelve months — money that would have materially offset the storage bill and put an idle, taxpayer-funded asset to some use rather than none. Whichever way that specific decision is judged, the fact that it had to be made at all is itself the failure: a well-sequenced project does not leave a ship that cost the state hundreds of millions of dollars sitting with nothing to do for the best part of a year.
None of this is a victimless accounting exercise. The $506 million equity injection confirmed in the 2026-27 Budget, on top of the earlier $75 million interim payment and the $400 million (approx.) expanded borrowing guarantee, is money drawn from the same Tasmanian budget that funds hospitals, schools and roads, either directly or through the debt the state now carries on TT-Line's behalf. An Auditor-General's insolvency finding against a state-owned corporation is a serious governance verdict, not a technicality, and it followed two years in which TT-Line's board disputed the government's account of events while the government said the board had not kept it properly informed — an accountability gap in which both sides pointed at the other while the bill kept growing.
The risk to the future
A ferry service — and a project-delivery model — still exposed
Tasmania will not have a fully in-service replacement fleet until at least 31 October 2026, the latest confirmed date, nearly nine years after TT-Line first announced the plan and five years after the ships were originally due. Until then, Bass Strait's freight and passenger task keeps riding on vessels approaching thirty years old, with the reliability and maintenance risk that implies for an island economy with no alternative crossing. Even once the new ships enter service, TT-Line carries a materially larger debt load and a recent formal insolvency finding on its record, meaning its capacity to absorb the next unexpected cost — a further wharf defect, a delayed certification, a fuel-price shock — is thinner than before the project began.
The wider risk is what this project teaches Tasmania's public sector about running the next one. Marinus Link, the Macquarie Point stadium and other major state-backed builds now under way will each depend on the discipline that failed here: locking in delivery-critical infrastructure on a timeline that actually matches the asset it is meant to receive, and giving a board and a minister enough shared, accurate information to catch a $9 million specification error before it becomes a $717 million political and financial crisis. A state the size of Tasmania cannot easily afford to relearn that lesson twice.
