It’s the controversial decision that miners say will revive the resources industry and has environmentalists predicting irreparable damage to the Great Barrier Reef.

Federal Environmental Minister Greg Hunt on Tuesday gave the go-ahead for three million cubic metres of dredge spoil to be dumped offshore in the Great Barrier Marine Park, 24km northeast off Abbot Point.

He also approved construction of the Adani-owned terminal 0 at Abbot Point and gave the go-ahead for the Arrow LNG facility on Curtis Island, near Gladstone, and its associated gas transmission pipeline.

Environmentalists are outraged the four major projects have been approved all at once, even though Mr Hunt says the dredging will be subject to ‘‘some of the strictest conditions’’ in Australian history.
