CLIMATE change predictions and rising sea levels have been reinstated in State Government planning.
The Palaszczuk government has announced a return to the former Bligh government policy to include a predicted 0.8m sea level rise along the Queensland coast.
The move affects planning and development for 36 local governments along the coastline and could see more developments referred to the state government for approval at an additional cost.
It affects Rules Beach at Baffle Creek, Tannum and Boyne Island but Agnes Water and Seventeen Seventy are the most impacted.
The new policy took effect on July 8 and is similar to the 'erosion prone area' policy repealed by the LNP government in 2014.
Agnes Water business owner Carolyn Cross owns land at The Springs near Rocky Point.
Under the new mapping her block is predicted to be underwater despite being 40m above the shoreline and 120m from the beach.
Ms Cross said she has spent the last seven years and hundreds of thousands of dollars trying to prove she can build on her beachside block.
Now she is right back to square one because every time the government changes its policy she has to fight for her right to develop the land.
"We have paid for studies that say even if there is a 0.8m sea level rise it won't affect our block," Ms Cross said.
"But they just draw a line on a map and now we are back to where we started."
Gladstone town planner Steve Enders says the full impact of the changes won't be obvious until the final review of the state government coastal management legislation.
"The real impact on landholders will be in changes to the Coastal Management Districts (areas where development applications are more likely to be referred for state government approval)," Mr Enders said.
The Urban Development Institute of Australia expects those changes to be announced before the end of the year. The state government did not provide comment before deadline.
