MORE action is needed to prevent the Great Barrier Reef being put on a World Heritage sites "in danger" list, environmental groups say.
WWF and the Australian Marine Conservation Society said not enough was being done, in a report on concerns and solutions for the reef's health.
While the Australian Government has committed about $2 billion to reef programs, the Academy of Science and natural resource management groups previously said it was not enough.
The World Heritage Committee will meet in June this year for a decision on whether the reef should be listed as a World Heritage Site in danger
But despite increased efforts since the listing was first raised in 2011, WWF Australia chief executive officer Dermot O'Gorman said the Federal Government needed to "lift its game".
He said a further $500 million was needed over the next five years to address the challenges facing the reef.
The WWF-AMCS report recommended the extra funding, a ban on all dredge spoil dumping in the reef's World Heritage Area and more resources and teeth for the Great Barrier Reef Marine Park Authority.
AMCS reef campaigner Felicity Wishart said while Environment Minister Greg Hunt had promised a ban on dredge spoil dumping in the marine park last year, it was not yet enacted.
She said, as most dumping occurred just outside the marine park boundary, a complete ban on dumping spoil in the World Heritage Area was needed.
Mr Hunt previously said the ban would be completed through regulations this month.
