THE popular North Stradbroke Island campsite at Adams Beach, Dunwich, will remain shut over Easter, after delays in a cultural heritage survey.
Straddie Camping management closed the bayside camping ground in December 2013 to renovate and tidy up the site.
But 16 months later, the levelled site, which used to offer 30 camping spots, is overgrown with weeds and littered with orange safety bunting.
Straddie Camping chief executive Clare Carroll said the cultural heritage survey was expected to be completed this month.
She said it would identify areas on the campgrounds significant to the island's Quandamooka people.
"We did think it would be completed before this but it is important to get it right so that nothing historical gets destroyed and lost forever," she said.
"We have had cultural heritage experts and archaeologists at the site and once the report is done it will be up to the indigenous community to decide how to proceed with upgrading the camping site."
Before the grounds were closed in 2013, 17 long-term leaseholders were told to move their caravans off the site so some cypress pine trees could be "restored".
Before being evicted, long-term leaseholder Karla Lennon, who is in a wheelchair, demanded to know what would happen to the park and when she could return.
She was told it was not known when the site would reopen or how many campers the reconfigured campsite would accommodate until designs were completed in October 2013.
Last week, Mrs Carroll said plans were on hold until results from the cultural heritage report were known but she hoped the grounds would be open for the September school holidays.
However, she said the toilet block had been renovated inside and rendered outside.
Adams Beach is one of eight camp grounds on the island managed by Straddie Camping.
The nearby Bradbury Beach site has three permanent residents and is also undergoing a facelift.
Grounds at Amity have undergone some changes with building starting on two eco cabins in May last year but yet to be completed.
Straddie Camping also closed vehicle access to the Basin for local residents citing safety reasons.
