For decades, Australia’s largest independent oil and gas company, Woodside, has eyed off a prize: the largest known unconventional gas fields in the nation.

But there’s a problem. The enormous Brecknock, Calliance and Torosa gas fields are hundreds of kilometres off the coast of Western Australia – buried underneath pristine coral reefs. To access it, the company would have to drill more than 50 wells around the Scott Reef system and pipe the gas 900 km along the ocean floor to a processing plant.
Now Woodside has an even larger problem. The state’s Environmental Protection Authority is it will reject this A$30 billion project, known as , which is part of Woodside’s much larger Burrup Hub project.
It would be unusual to see the state authority reject a project of this size – they’re more commonly approved with conditions. But the authority is clearly concerned about the potential damage the giant gas project could do. The project has been mired in controversy, attracting 800 public appeals and more than 400,000 signatures on against it. Conservationists at news of the rejection.
Has this project by Australia’s homegrown answer to Big Oil been shut down? Not quite. The authority has only made a preliminary decision. Woodside has vowed to keep pushing for a green light – and it of federal Resources Minister, Madeleine King.
But because these reefs are on an important migration route for endangered pygmy blue whales, federal Environment Minister Tanya Plibersek may have to weigh in.
What happens next will tell us a great deal about who holds sway within the Albanese government.
How big is this project?
If approved, the Browse project would feed gas into Woodside’s proposed Burrup Hub, the company’s which would become one of the largest liquefied natural gas (LNG) processing hubs in Australia. Conservationists have described Burrup as a “climate bomb”, which twice the emissions of any other fossil fuel project seeking approval.
The Browse gas has high levels of carbon dioxide (12% CO₂), and gas extraction commonly leads to escaped methane, a particularly potent greenhouse gas. Last year, Shell citing concerns about profitability and carbon.
But greenhouse gas emissions aren’t usually covered under an environmental authority’s remit. The Western Australian authority reportedly rejected the Browse project on conservation grounds. A freedom of information request by the Nine newspapers the authority sent in February to Woodside, indicating the project was “unacceptable” due to the likely impacts on Scott Reef.
The concerns are well-founded. The project would threaten the habitat or migratory routes of endangered species such as pygmy blue whales, manta rays, whale sharks and nesting green turtles. Gas flaring would disorient migratory birds and young turtle hatchlings.
Noise pollution from drilling, piling and other infrastructure would cause stress and impact habitat. Chemical pollutants including drilling fluid and treated sewage would be released into the water.
High speed transfer boats could threaten whale migration paths. Then there’s the chance of an oil blowout. If this happened, it for marine life.
There’s gas extraction could cause Sandy Islet, the only part of Scott Reef above the high tide mark, to be submerged, risking the destruction of a for green turtles.
In the public interest?
Woodside argues exploiting these enormous gas fields to avoid a forecast gas shortage in WA – and to firm up energy security in Asia.
But the state a gas shortage. Even if it did, WA has a domestic reservation policy requiring LNG producers to reserve 15% for the domestic market. Given a recent WA parliamentary inquiry found major gas companies are only reserving 8% of the state’s gas , it would be far simpler to enforce the current reservation policy rather than crack open new gas under a coral reef.
What’s coming next?
A final decision by the state Environmental Protection Authority is yet to be handed down. But even if the decision is a clear no, it’s hard to see the company giving up.
In that case, Plibersek would likely have to weigh in. She is tasked with making determinations of national environmental significance under Australia’s main .
These laws don’t account for damage done by emissions, meaning Plibersek could not reject Woodside’s proposal on climate grounds. But the act does cover protection of endangered species, migratory species and the marine environment.
The endangered pygmy blue whale is found in Western Australian waters -including Scott Reef. Under Australia’s environment laws, the species has had a severe drop in population and has fallen by at least 50% over ten years or three generations.
Plibersek could stop the Browse project due to its impact on the pygmy blue whale, as this species has an existing .
When a recovery plan is in place, our laws state the federal minister cannot approve a project inconsistent with or in contravention of the plan. But the whale’s recovery plan expires next year.
Gas – or nature?
When the Albanese government came to power, it promised stronger action and a reversal of the of the natural world.
But what happens when the government’s priorities ? This year, King launched the government’s future gas strategy, a role for fossil gas out to 2050.
For so long when a fossil fuel company has applied to open new gas fields or coal mines in Australia the answer has been yes. A decision by WA’s environmental authority has challenged that. But it’s not a hard no.
If Browse gets federal approval, it will be a very clear sign of the government’s priorities.
