Southern Gold Coast land is set to be transformed into one of the largest eco-parks in the country through compulsory acquisition from the defiant owners.

The state government has announced it will begin the process to acquire 148 hectares for the Currumbin Eco-Parkland locally known as Martha's Farm or Martha's Vineyard.

Minister for the Environment Meghan Scanlon says the decision would deter the ambitions of new developers and protect natural and delicate rainforest.
