Scott Reef is not a household name, but it is 15 million years old, home to more than 2,000 marine species, and currently sitting 3 kilometres from a proposed gas drilling project with up to 50 wells attached to it. This week, WA's own Environmental Protection Authority used the word "irreversible" in writing. Here's what that actually means.
What's actually being proposed
The project in question is Woodside's Browse development, which would drill up to 50 gas wells plus seven wells for dumping carbon, some as close as 3km from Scott Reef, off the Kimberley coast. That is a serious amount of infrastructure for a reef most Australians only heard of this week, which is sort of the point: you don't usually hear about the reef until something is about to happen to it.
The watchdog's own language doesn't hold back
According to a draft letter from the WA EPA and government departments, reported by the Australian Marine Conservation Society (27 October 2026), the risks include a potentially "catastrophic" oil spill, "irreversible" harm to nesting habitat for threatened green sea turtles from seabed subsidence, and significant disruption to pygmy blue whales from underwater noise and ship traffic. Scott Reef is reportedly the only currently identified foraging ground for the whales between Timor and southern Australia on their migration south, so it is doing a lot of ecological heavy lifting for one small patch of ocean.
For scale: the 2009 Montara oil spill released more than 34 million litres of oil over 74 days, and by Woodside's own modelling, a spill at Browse could be up to 30 times larger again. Regulators don't usually reach for a word like "catastrophic" lightly, so when the drafting itself is this blunt, it's worth sitting up for.
A reef that's been quietly outdoing the famous one
AMCS chief executive Paul Gamblin put it plainly: "Scott Reef rivals WA's World Heritage-listed Ningaloo Reef for marine diversity." Fifteen million years in the making and over 2,000 species calling it home is a genuinely wild stat for a reef that doesn't get a tourism campaign, a mascot or a single influencer dive video. It has just been getting on with being one of the richest patches of ocean in the country while nobody was looking.
The actually good bit: this is the system doing its job
Here's the glass-half-full part. This isn't a campaign group making noise, it's WA's own environmental regulator applying the precautionary principle in a draft assessment, on the record, before a single well goes in the ground. The EPA's final assessment is expected later this year, and the ultimate call sits with the WA and federal environment ministers, who AMCS is now publicly asking to reject the proposal. A government department using the word "unacceptable" about a multi billion dollar gas project, in writing, ahead of approval, is exactly the kind of process working-as-intended moment that's easy to miss under a scary headline.
It's also a handy reminder of why ocean health and bathroom habits aren't as unrelated as they sound. We've written before about why we chose home-compostable over recyclable packaging, and the short version is the same logic applies here: what happens upstream, on a reef or in a factory, ends up downstream, in the ocean, eventually. Reef diversity and plastic in the bathroom bin are two ends of the same waterway.
One more thing worth knowing
If you want another recent example of Australians putting money and attention behind ocean conservation rather than just talking about it, we covered Radiohead's 2027 Australian tour bankrolling ocean conservation a few weeks back. Turns out reef protection has better company than you'd think.
A reef that's been quietly thriving for 15 million years just got a government department to use the word "catastrophic" on its behalf. Honestly, that's a better review than most things get in 15 million years.
