Exclusive: Queenslanders Howard and Shirley Hill have called site 75 at Dicky Beach Holiday Park home for more than 30 years.

They poured their life savings into building a home on the long-term site, one where their grandkids and great-grandkids can come for holidays and there's always time for a beer on the deck at the end of the day.

But under a new council plan, Howard and Shirley's little slice of paradise may soon be worth nothing.

Proposed changes to the residential area of Dicky Beach Holiday Park will see the land where the Hills' home is located, along with more than 80 others, returned to its "intended purpose" as camping and recreational reserve sites.

The change is set to come into effect in May 2026 and when it does, residents will no longer be allowed to sell their homes to new owners.

It has rendered the homes of about 100 residents "virtually unsellable and worth nothing".

"It's devastating," Howard told 9news.com.au.

"We put $110,000 into this [home] and we could have sold it six months ago for $350,000.

"Now it's not worth $3.50, if council gets what they want."
