COOLUM community groups are considering boycotting developer Sekisui's forums, arguing it is "stacked" against them and paying lip service to consultation.
Prominent architect and Project Coolum member Dragi Majstorovic said community forums, which begin this Friday, were "37 to 3" against the locals.
A Sekisui House spokeswoman has denied this is the case, saying there are 10 representatives of Coolum/Yaroomba, including residents, business owners and community groups.
"Each session has approximately 18 to 20 participants," she said.
Mr Majstorovic feared events were "set up with Sekisui's consultants to talk about how far they can push the limits of the town plan".
"The community is not interested in that. They are interested in adhering to it," he said.
The Daily revealed on Tuesday Sekisui House was planning a new round of community forums, starting with a "blank page", to discuss the future of its 19ha Yaroomba site.
Development Watch's Lyn Saxton, who has been invited to the forum, said the community groups would meet Thursday to discuss whether they would attend.
Coolum Residents' Association's Mark Bizzell said the groups only had a few options - to attend and listen to consultants "tell us why this new deal is the one for us" or boycott the meeting.
"This will send a clear message to Sekisui their tactic and strategy is seriously flawed and one sided," he said.
The Sekisui spokeswoman said she had repeatedly assured Ms Saxton further meetings specifically for Coolum's interested groups could follow.
"It is important that Development Watch takes part and shares their viewpoint, we genuinely want them to participate," she said.
