THE State Labor Government's new dredging plans for the expansion of the Abbot Point coal terminal have been submitted to Federal Environment Minister Greg Hunt.

Queensland Premier Annastacia Palaszczuk said the new proposal, which has the support of port proponents Adani and GVK, would see dredge spoil dumped on land on the site known as T2, adjacent to the existing coal terminal, and not on the Caley Valley wetlands or within the Great Barrier Reef World Heritage Area.

This is the third proposal relating to the disposal of dredge spoil to come before Minister Hunt's office and was referred to him on April 17.

A representative for Minister Hunt said the revised proposal would be considered under national environment law, and that the Queensland government expected a full Environmental Impact Statement to be carried out as part of the assessment process.

"The proposal is for onshore relocation of dredge material and will not require disposal in the Caley Valley Wetlands," the representative said.

"The amount of dredging proposed is significantly smaller than previous proposals (and) it's less than three per cent of what was proposed under the Bligh Labor Government.

"Onshore disposal has always been our preferred option and that's why we're ending the century-old practice of dumping capital dredge material in the Great Barrier Reef Marine Park."

But news of the proposal's referral to Mr Hunt's office has drawn the ire of local Australian Marine Conservation Society Great Barrier Reef Community Campaigner Cherry Muddle.

"People were shocked to learn that the Queensland Government has submitted new plans to dredge 1.1 million cubic metres of seabed at Abbot Point, and dump the spoil at Terminal 2, which is adjacent to turtle nesting beaches and the Caley Valley Wetlands," she said.

"The reef supports 69,000 jobs in Queensland.

"It is the most important economic driver to the local economy.

"The Whitsundays represents 1 per cent of the total area of the Great Barrier Reef Marine Park, yet it receives 40 per cent of all marine tourism in the Great Barrier Reef."

Ms Muddle said the World Heritage Committee would decide in June whether or not to list the Great Barrier Reef as "in danger".

"We must urge our government not to allow damaging and unnecessary port expansions to risk our national treasure."

The Queensland Government's new proposal for Abbot Point is open for public comment until May 1.
