The Australian government said no to a coal mine project near the Great Barrier Reef because it could cause damage that cannot be fixed. The Great Barrier Reef is a large group of coral reefs in the ocean near Australia. The mining project was going to be less than 10 kilometers from the reef on the Queensland coast. The minister who makes decisions about the environment and water, Tanya Plibersek, said that the reef could be in danger if the mine went ahead. She said there could be pollution and other problems that would hurt the plants and animals there.

Many people told the government their opinions about the mine. UNESCO also said they want the reef to be better protected. The government promised to spend a lot of money to take care of the reef and help it deal with climate change. But last year, the reef had a big problem with too much heat from the water. This was because of climate change. The new government promised to do more to help the environment.
