Prime Minister Malcolm Turnbull said Aus$60 million ($48 million) would go into the new drive, with just over half to be spent on incentives for farmers to prevent agricultural pollutants from running into the reef.

Funds will also go towards increasing the number of patrol vessels and divers targeting the starfish, he said.

“It is a vibrant, resilient ecosystem and one of the best-managed coral reef ecosystems in the world,” Turnbull said in a statement.

“While it is facing increasing threats, we intend to remain leaders in reef management,” he said, adding the fund would support the development of new technology to help protect the reef.

The reef is also reeling from significant coral bleaching due to warming sea temperatures linked to climate change.

Canberra in 2015 narrowly avoided UNESCO putting the site on its endangered list, and has committed more than Aus$2.0 billion to preserve it over the next decade.

But it has been criticised for backing a huge $16 billion coal project by Indian mining giant Adani near the reef, which environmentalists warned would harm the natural wonder.

Conservationists said Monday the government’s latest funding announcement did not go far enough and action is needed to slash greenhouse gas emissions to prevent warming sea temperatures.
