Quieter rides and cleaner air, but the cost is hidden in distant mines
Sydney's harbour ferries, long defined by the low rumble of diesel engines, are edging toward a quieter future — though the path there has proven longer than anticipated. New South Wales has signed contracts for a single Australian-built electric ferry to begin trials in 2028, two years behind the government's original promise, with a broader ambition to retire all 40 diesel vessels by 2035. The announcement is both a milestone and a reminder that the transition to cleaner public transport is rarely as swift as political will alone can make it — and that the materials powering that transition carry their own moral weight.
- A two-year delay has quietly eroded confidence in the government's original 2026 trial target, raising questions about whether the 2035 full-fleet transition is equally optimistic.
- The single 24-metre vessel must prove itself across a full year of real harbour conditions before any further electric ferries are ordered — the entire fleet transition hinges on one boat.
- A $30 million wharf at the Sydney fish market, the ferry's intended 2029 home, remains in the design phase, meaning infrastructure is racing to catch up with the vessel itself.
- NSW's anti-slavery commissioner has flagged that the lithium-ion batteries powering this green transition may be linked to forced labour in Xinjiang and the Democratic Republic of Congo, casting a shadow over the clean-air narrative.
- The broader net-zero public transport push is real — 500 electric buses running, 7,500 more on order — but diesel still dominates the network, and the harbour ferries remain among the last to change.
Sydney's diesel ferries have crossed the harbour for decades, their exhaust part of the city's sensory fabric. That era is now officially in its final chapter — though the timeline has stretched. On Monday, New South Wales announced contracts signed for a 24-metre battery-electric ferry, designed by Incat Crowther and built by Tasmanian shipyard Richardson Devine Marine, to begin trials in 2028. The government had originally aimed for early 2026. Two years have slipped.
Transport Minister John Graham cast the delay as the natural pace of genuine progress — a quieter, cleaner harbour crossing worth waiting for. The vessel will enter passenger service in 2029 on the new Sydney fish market route, though the wharf serving that destination is still being designed as part of a $30 million project. The 12-month trial, run jointly by Transport for NSW and private operator Transdev, will test the ferry's reliability, its charging systems at Barangaroo wharf, and the day-to-day experience of passengers and crew. No further electric ferries will be ordered until that evidence is in hand.
The stakes behind this single vessel are considerable. In 2024, the Minns government committed to replacing all 40 of Sydney's diesel ferries with electric or hydrogen-powered alternatives by 2035 — a target that remains policy, even as the trial delay signals how complex the transition truly is. The ferry sits within a wider net-zero push: last month, a $1.9 billion deal was announced to run buses, trains, and light rail on fully renewable energy, and more than 500 electric buses are already on the road, with thousands more on order.
Yet fossil fuels still power most of the state's public transport, and a troubling question has surfaced in the supply chain. In March, NSW's anti-slavery commissioner found that Transport for NSW had not adequately investigated potential forced labour links in its lithium-ion battery sourcing — particularly from mining operations in Xinjiang and the Democratic Republic of Congo. As Sydney prepares to clean the air above its harbour, it will also need to account for the human cost buried in the batteries making that possible.
Sydney's ferries have rumbled across the harbour on diesel engines for decades, their exhaust mixing with salt spray and the cries of gulls. That era is about to change, though more slowly than the government once promised. On Monday, New South Wales officials announced they had signed contracts for a new electric ferry—24 metres long, battery-powered, designed and built in Australia—to begin trials in 2028. The delay is significant: the government had originally targeted early 2026 for the vessel to start testing. Two years have slipped away.
Transport Minister John Graham framed the shift as inevitable progress. The new ferry, he said, would deliver a quieter ride and cleaner air to those crossing the harbour. It will be built by Richardson Devine Marine, a Tasmanian shipyard that has already constructed seven Parramatta River class ferries—diesel-powered vessels designed with the capacity to be converted to electric propulsion later. The design comes from Incat Crowther, a Sydney-based naval architecture firm. When the trial ferry enters service in 2029, it will operate on the newly opened Sydney fish market route, a destination that opened its doors at the start of this year but has been waiting for ferry access. The wharf there remains in the design phase, with a $30 million project still in development.
The 12-month trial will be run jointly by Transport for NSW and Transdev, a private ferry operator. Howard Collins, the Transport for NSW coordinator general, explained that the testing will examine how the vessel performs in actual working conditions—its reliability, its charging systems (to be installed at Barangaroo wharf), and the experience of both passengers and crew. This data will be crucial. The government has not yet committed to ordering additional electric ferries; any expansion of the fleet depends entirely on how well this single vessel performs.
The broader ambition is substantial. In 2024, the Minns government announced a plan to replace Sydney's entire fleet of 40 diesel ferries with electric or hydrogen-powered vessels by 2035. That target remains official policy. But the two-year slip in the trial start date signals the complexity of the transition. Building new vessels, designing charging infrastructure, and testing new systems in a working harbour takes time.
This electric ferry trial sits within a larger push toward net-zero public transport across New South Wales by 2035. Last month, the government announced a $1.9 billion deal to run all-electric bus, train, and light rail services on fully renewable energy from next year. More than 500 electric buses are already operating, with 7,500 more on order to replace the state's fleet of 8,000 diesel buses. Yet fossil fuels still power most of the state's public transport network—the majority of buses, all the diesel ferries, and regional and intercity trains.
One complication has emerged in the supply chain. In March, the NSW anti-slavery commissioner found that Transport for NSW had not taken adequate steps to address potential forced labour concerns in the sourcing of lithium-ion batteries, particularly regarding mining operations in Xinjiang, China, and the Democratic Republic of Congo. The finding raises questions about the human cost embedded in the technology meant to clean up Sydney's air. As the government moves forward with its electric transition, it will need to reckon with where and how these batteries are made.

Why the two-year delay? What happened between 2026 and 2028?
The government doesn't spell it out, but building a new ferry from scratch—designing the charging infrastructure, getting the shipyard ramped up, navigating approvals—takes longer than press releases suggest. Two years is actually not unusual for maritime projects.
So this is just one ferry being tested. What happens if it fails?
Then the entire 2035 fleet replacement timeline becomes questionable. The government hasn't committed to ordering more electric ferries until they see how this trial performs. It's a cautious approach, but it also means the whole transition could stall.
The fish market route—is that a symbolic choice, or practical?
Probably both. The new market opened this year but has no ferry service yet. Using the trial ferry there means the government gets real passenger feedback on a route that's already waiting for service. It's not a backwater test; it's a working route.
What about those battery supply chain concerns the anti-slavery commissioner raised?
That's the uncomfortable part. You're replacing diesel with electric, which is cleaner air in Sydney. But the lithium for those batteries may come from mines where workers aren't treated fairly. The government hasn't announced how it plans to address that.
Is 2035 realistic for replacing all 40 ferries?
It depends entirely on this trial. If the electric ferry works well and charging infrastructure can be built at scale, maybe. If there are problems, the timeline will slip again. The government is being cautious—they're not ordering a fleet until they know it works.
