The project, which was announced last year, proposed a 5.6 hectare extension into Freycinet National Park to accommodate the construction of 12 hardstands and 12 cabins at Freycinet Lodge.

While developers of the proposal have said the extensions would be “sensitive” and have no visual impact, its detractors have described the project as “exploiting public land”. 

In recent weeks critics of the plan have gone about collecting signatures from RACT members to force a special general meeting with the company’s board. 

A separate meeting has since been scheduled between the RACT board and a handful of environmental groups including Freycinet Action Network, The Wilderness Society and Tasmanian Conservation Trust.

Despite already having sufficient support to force a special general meeting, Freycinet Action Network member Sophie Underwood said her organisation would continue to collect signatures until learning the outcome of the upcoming meeting with environment groups.

“To hold a special general meeting you have to have 50 signatures but it's restricted to RACT members who can put their name in the petition,” Ms Underwood said.

“We've got over 250 already and we're going to still continue to collect names.

“We'd like to hear from as many members as possible who are supportive of the petition.”

In a statement on Friday, an RACT spokesman said the organisation had engaged tourism entrepreneur Brett Torossi to assist in developing concepts for the project, which was still in a “conceptual stage”.

“The (RACT) board met earlier this week and received a briefing about the status of the proposed development currently under consideration,” the statement read.

“The project is still in a conceptual stage and it would be premature to release specific details.”

The spokesman said in a member survey compiled earlier this year, an overwhelming majority said they supported "improving and developing" Freycinet.
