The Ningaloo Reef, a world heritage-listed site off the coast of Western Australia, is renowned for its vibrant marine life and breathtaking underwater landscapes. However, recent reports have painted a grim picture of its current state. Divers and conservationists have brought to light the widespread coral bleaching that is ravaging this natural wonder, likened to an ‘underwater bushfire’ by those witnessing its effects firsthand.
The Australian Marine Conservation Society (AMCS) has been vocal about the distressing situation, with WA Director Paul Gamblin expressing his heartbreak over the images and footage emerging from the reef. The visuals show vast stretches of once-colourful coral now turned ghostly white, a clear sign of the environmental stress they are under.
Coral bleaching occurs when corals, stressed by changes in conditions such as temperature, light, or nutrients, expel the symbiotic algae living in their tissues, causing them to turn white. While bleached corals are not dead and can recover if conditions return to normal, prolonged stress can lead to their demise.
The cause of this widespread bleaching is a marine heatwave that has been building for months, threatening the delicate ecosystem of Ningaloo Reef. This heatwave has already had dire consequences, with over 30,000 fish washing up dead on Gnoorea Beach, just south of Ningaloo, last month. The environmental toll is mounting, and the AMCS is urging the government to take immediate and decisive action.
‘To see beautiful coral reefs bleaching white at Ningaloo icons, including Turquoise Bay, Coral Bay, and Bundegi, is just devastating,’ said Gamblin. ‘This is a red-alert moment for Ningaloo.’
The call for action is not just about preserving natural beauty; it’s also about protecting the livelihoods of coastal communities. Ningaloo’s tourism industry, as well as fishing businesses, depend on a healthy marine environment. The current crisis serves as a stark reminder of the existential threat posed by climate change to these industries and the communities they support.
The AMCS is demanding greater transparency from state and federal ministers, calling for regular updates on the marine heatwave and its impacts. The silence from the government, especially after the fish kill event, has been a source of frustration for environmentalists and residents alike.
The situation at Ningaloo is a microcosm of a global coral crisis. Reefs around the world, including the Great Barrier Reef, have been facing similar threats due to rising sea temperatures and climate change. Scientists have been warning of these dangers for decades, and now, the evidence of their predictions is unfolding before our eyes.
Gamblin’s plea to the government is clear: ‘Reduce pressure on the stressed marine environment.’ He also emphasises the need to assess the status of other WA coral reefs, such as Scott Reef and the Rowley Shoals, to understand the full extent of the bleaching event.

The reefs seem to be affected by bleaching to various extents depending on the location of the reef. Maybe some corals are more adaptable to temperature changes than others may be.
Either way I don’t know what any government in Australia could do about rising marine temperatures.
Hopefully the corals will learn to adapt to greater fluctuations in sea temps.
What an idiotic headline. Journalism is dying.
Totally Agree Winston. 4 years ago, the GBR was reported to have a massive bleaching problem only to return to normal health within two years or so with record levels of coral.
