Southlake Business Chamber and Community Alliance issued the questionnaire to businesses and community groups in response to a letter published in the Lakes Mail.

In the letter, Cooranbong resident Jeff Bromage asked for the chamber to publicly state whether it opposed or supported the plan.

"We emailed the questions to everyone on our emailing list, and received a very small response," Southlake Business Chamber and Community Alliance president Robert Kemmis said.

There was "a very small number of people who were totally negative" about the plan, he said.

Mr Kemmis said the response was not sufficient to warrant the chamber opposing the development.

The twin service stations would provide 24-hour fuel, along with restaurants and cafes.

"From a chamber point of view, we're interested in employment and business development," he said.

"On that basis, it's difficult for the chamber to be anti the twin service stations."

Cooranbong Business Chamber and Community Alliance has concerns the plan would take business from Morisset and Cooranbong.

Mr Kemmis said he had seen no evidence to suggest the plan would have a big impact on local businesses, including petrol stations.

Supporters argue that the twin service stations would increase price competition.

They would also generate jobs, Mr Kemmis said.

"If we can get another 170 jobs, that's a plus for the area," he said.

Given the loss of jobs associated with the Sanitarium factory closure at Cooranbong, coupled with the "hundreds of people" coming to live in new housing estates in the area, local employment was a key consideration, he said.

"Every 170 jobs that can be found in the local area are important."
