What if Australia’s worst offshore oil spill hasn’t happened yet?
I’m terrified by the thought.
Our new report in partnership with Environs Kimberley analyses Woodside’s own oil spill modelling and it reveals a worst-case blowout at the corporation’s proposed Browse gas project at Scott Reef could be up to 30 times larger than the Montara oil spill – one of Australia’s worst environmental disasters to date.
Woodside’s own modelling warns that oil pollution could spread across Scott Reef, the Kimberley coast and beyond, with impacts Woodside itself describes as “severe”, “potentially irreversible” and “catastrophic”.

What’s at stake?
Scott Reef really is like nowhere else on Earth.
Scott Reef is Australia’s largest freestanding oceanic reef, a pristine marine ecosystem that has thrived for around 15 million years. About 270 kilometres off the Kimberley coast, it supports more than 2,000 marine species, including endangered pygmy blue whales, nesting green sea turtles, the endangered dusky sea snake and ancient corals.
Yet Woodside wants to drill up to 57 toxic wells around and underneath it, causing decades of deafening seismic blasting, light and noise pollution, shipping traffic and, of course, the risk of a ‘catastrophic’ oil spill.

What did Woodside’s modelling find?
Before Browse can be approved, Woodside is required to assess what could happen if something goes wrong. We analysed the corporation’s own environmental assessment documents, and the findings are deeply concerning.
Woodside’s modelling shows that the most severe Browse scenario would be the worst oil spill in Australian history, releasing up to 893,739 barrels of condensate into the Timor Sea. For context, the Montara oil spill released 30,000 barrels of oil.
A blowout of this scale could see oil spread hundreds of kilometres, reaching some of Australia’s most important marine environments, extending into Indonesian and Timor-Leste waters and even washing up along parts of the Kimberley coast. Entrained oil – oil mixed throughout the water column – is predicted to travel up to 863 kilometres from the spill site.
The modelling identifies potential impacts to at least nine marine parks, eight reefs and three Indigenous Protected Areas, as well as important habitats for endangered species, including pygmy blue whales, green sea turtles, seabirds and other marine life.

These aren’t just places on a map. They are globally significant marine ecosystems that support ancient coral reefs, endangered wildlife, tourism, fisheries and coastal communities. A spill of this scale wouldn’t simply affect one reef; it has the potential to impact an entire connected marine ecosystem.
Why this matters now
The most important thing is that Browse has not yet been approved. That means there is still time to stop Browse and the serious risks outlined in Woodside’s own modelling.
The science has been done. The risks have been modelled. The decision now rests with the Australian Government.
Governments are often forced to respond after environmental disasters happen. This is one of those rare moments where they have the opportunity to act before one does.
What you can do
Together, we still have the power to stop Woodside and save Scott Reef.
You can help by:
- Sending an email to Environment Minister Murray Watt and Prime Minister Anthony Albanese, calling on them to reject Browse.
- Sharing this story to help more Australians understand what’s at stake.
- Encouraging your friends and family to take action.
The more people who support saving Scott Reef, the harder it is for governments to approve Woodside’s drilling plans – Browse.
Together, we can ensure a reef that has existed for millions of years is known for its incredible biodiversity – not as the site of Australia’s worst oil spill.
Let’s save Scott Reef.

Sailing with the voices of Kioa
A beacon of love
On an outer island of Fiji, two thousand nautical miles from Sydney, is a shining light of hope and resilience for our troubled world.
The island of Kioa is home to a Tuvaluan community who migrated from their atoll of Vaitupu in the late 1940s. It is a land of warm hearts, big smiles, and deep cultural roots; a place where the sound of a conch still summons the island together, where islanders paddle out to fish in carved outrigger canoes, and healthy happy children walk barefoot to school.
Here, culture is life. Kioans live sustainably through their traditional knowledge and practices. The island is alive with song, dance and the rhythms of a life tied to the tides, the winds, and the seasons.

Facing the future
Greenpeace has been lucky to have a relationship with Kioa for a number of years now, and we are continually learning from this remarkable community.
Last week, as part of our Voyaging Oceania project, we returned to the island. Our purpose was twofold —- to carry messages from the island to leaders gathering in Nadi this week for the Pacific Pre-COP, and to support the Kioa community in their efforts to improve water security for the island.
Unlike Tuvalu itself, with its eight atolls, Kioa is a mountainous, forested and richly fertile island. It will remain habitable far into the future. Kioans did not initially migrate from Vaitupu due to climate change, but the move was prophetic. They now have a lifeboat.
However, even Kioa faces challenges on our rapidly warming planet, in particular when it comes to water. Climate change is shifting once reliable rainfall patterns. On top of this, the island is already feeling the effect of this year’s intensifying El Niño event, which for Fiji means reduced rainfall and prolonged dry spells.
Right now, fresh water has to be carefully rationed, and is only available for a few hours a day. During last week’s visit aboard our campaigning ship Oceania, Greenpeace was privileged to work with the Kioa community on a new solar-powered water distribution project for the island.
Designed and led by the island, the project involves using a solar pump to move water from a reliable source to a storage tank and then using gravity to distribute the water around the village.
It was a lesson in how local knowledge and ingenuity can be the backbone of today’s climate solutions. To build a dam around the source, the local community knew the exact spot where they could gather gravel at low tide to mix with the cement. They took only what was needed, knowing that all resources must be carefully conserved. Kioa has no roads and no machinery, and it was an all-of-island effort to carry the materials up to the project site, including many heavy bags of sand and rock.
Such projects truly bring to life the vision of a resilient, locally-led, fossil fuel free Pacific.
Voices of wisdom
During our four precious days on Kioa, Greenpeace’s Pacific team sat with the island’s elders as they shared stories and experiences for us to carry with us to the Pre-COP. During a fun filled morning at the island’s school, Kioa’s children shared what they love about their life on Kioa and what they want to see nourished and protected. They wrote these messages on flags which will fly proudly from Oceania in Nadi.

It is hard to describe the warmth and generosity we experienced once again in Kioa. Meals were lovingly prepared for us, each one the product of many hours and many hands needed to fish, to grow, and to prepare. In the evenings we were entertained with traditional songs and dances, each one pulsing with an indescribable energy. For Kioans, these rituals are of course more than entertainment. This is how they have encoded and kept alive countless generations’ worth of traditional knowledge, and the wisdom that has enabled them to flourish sustainably and peacefully.
We are now sailing on to Nadi, inspired by the warmth and wisdom of Kioa, and determined to help take the voice of Pacific climate justice to the world.

A visit to Kioa is a reminder of what life can and should be. It is a reminder of what we are all fighting to protect. It is a reminder of the power of local knowledge and culture, and of listening to those on the climate front line. And it’s a reminder that tackling climate change is above all about building community, and respecting and loving each other.

Governments that support climate science must stand firm against naysayers
Piers Forster is Professor of Physical Climate Change and Director of the Priestley Centre for Climate Futures at the University of Leeds. He has previously served as a lead author on several IPCC assessment reports.
Evidence of a rapidly changing climate and our improved scientific understanding is compelling nations to act, but not always in a good way. The science itself is facing well-organised obstruction.
The consequences of politicising the evidence are now more apparent than ever, especially in the run-up to a crucial intergovernmental climate meeting taking place in Addis Ababa this week.
On the agenda is a proposal that would prevent all governments from being able to use the most up-to-date analysis of options for combatting climate change at a critical stage in UN negotiations.
The meeting is the 65th session of the Intergovernmental Panel on Climate Change (IPCC), the body charged with providing gold-standard scientific and economic evidence on climate change to the world.
Often characterised as a scientific organisation, the IPCC is actually a forum of governments that commissions assessments from scientists from across the globe. This unique effort is doubly important as it represents the world’s only climate science reports that are approved by consensus among the 195 countries that make up its membership.
But this consensus also means that governments can regulate the IPCC’s reports and timescales. Countries can make it difficult for their scientists to participate or even withhold the organisation’s budget.
By doing so, they can place a straitjacket on the production of analysis that these self-same governments are obliged to consider when they assemble under a different umbrella – the UN Framework Convention on Climate Change (UNFCCC), which relies on the findings from the IPCC to guide negotiations.
When it works well, this intergovernmental approach means that countries agree on, and have a firm, authoritative scientific basis for acting on the evidence in a cooperative way.
Until now, the system has largely functioned as it should, despite a certain amount of posturing and politicking. This month, however, could be the time when that delicately balanced state of affairs comes to an end.
Enemies of science?
The vast majority of governments – in Europe, Africa, Southeast Asia, Latin America and most importantly the small island developing states which sit on the frontlines of climate impacts – want the three main parts of the IPCC’s current assessment report (AR7) finished by the end of 2028. That would mean its conclusions can inform the next Global Stocktake – the five-yearly process set up under the Paris Agreement where governments review progress on climate action and ideally commit to stronger efforts.
Against this view stands a handful of major emitters who are determined that the IPCC’s upcoming report on mitigation – reducing climate-heating emissions – will not emerge until after that crucial political decision-making point.
The figureheads for this group are Saudi Arabia and India, with a few others such as Russia lurking in the background. Finding the Saudis here is absolutely expected, but India’s presence is more surprising given President Narendra Modi’s commendable commitment to building a clean energy economy, most notably his leadership of the International Solar Initiative.
As science comes under attack at UN talks, climate movement splits over how to respond
Underneath pretexts of giving the authors more time, or making it fairer in terms of who can contribute, they have a hidden motive: if the report on mitigation is delayed beyond the second Global Stocktake, the same governments that delayed it will then argue that the stocktake cannot meaningfully discuss vital mitigation action without the latest report, effectively delaying more ambitious agreements on cutting emissions by another five years.
It is the duty of every government that professes to care about climate change to oppose such a retrograde step. There are worrying signs, however, that some governments which are highly influential within the IPCC system may be about to cave.
No time to appease
What seems to be happening is that in the face of signals that the Saudis, for example, are prepared to block the IPCC’s budget if they don’t get their way, some governments are leaning towards appeasement, i.e. publishing the mitigation report only after the Stocktake been has completed, just to keep the whole process moving – better a bad agreement than no agreement.
This would be a major error of judgement, for two reasons.
One is that appeasement will not stop the naysayers’ moves to derail climate action â€
