A planned $592 million resort on Great Keppel Island is one step away from approval after the state government finished its environmental assessment.
The proposed resort off Rockhampton would have a 250-berth marina and create more than 1000 jobs plus construction positions, the Deputy Premier Jeff Seeney said.
Tower Holdings wants to build the low-rise resort and says it "aims to deliver the most environmentally sustainable eco-tourism resort ever envisaged in Australia", according to the project's website.
Mr Seeney said there were 176 public submissions, which raised about 300 issues.
"If it goes ahead, this will be one of the biggest tourism developments in Australia, and a major boost for both the construction and tourism industries," Mr Seeney said in a statement.
Government agencies will review the final environmental impact statement and report to the Queensland coordinator general, who will make the final decision.
The federal government in 2009 rejected a more ambitious $1.1 billion proposal for the island because it would have had unacceptable environmental impacts.
