A POSSIBLE Badgerys Creek airport remains up in the air, unlike Blacktown Council's official stance on the matter.
Councillors voted in support of the council to continue to oppose an airport, citing concerns about noise, air pollution, impact on development and threat to Sydney's water catchment.
The council will seek support from other local government stakeholders and request Western Sydney Regional Organisation of Councils to adopt the same position.
A request for a delegation to meet with Prime Minister Tony Abbott and relevant ministers to outline the council's concerns will also be made.
Mayor Len Robinson was the only one to oppose the motion while Karlo Siljeg, Mark Holmes and Walter Smith abstained.
The mayor remains undecided about an airport and said current speculation was nonsense.
"I'm undecided until we know what's required," Councillor Robinson said. "We're waiting for the government to make its decision. Until then, we don't know what's going to happen. Then, we can look at noise studies and possible flight paths."
Liberal councillor Jacqueline Donaldson supported the motion but wants more information.
"The big problem is we don't have any current reports," she said. "The information we have is based on reports from 1997.
"We'd never vote on a development before we saw detailed plans from a developer yet we're being asked to accept an airport with no plans or financial breakdowns.
"If we could be supplied with detailed plans and environmental reports and costings we could make a more informed decision."
Labor councillor Stephen Bali, who's also the secretary of the new No Badgerys Creek Airport, Inc said civic leaders shouldn't be fence-sitters.
"At the end of the day we're going to have an airport and it's going to be 24-7," he said. "There are 50 reports out there.
"You either agree with noise or you don't."
He said the public has been bombarded with arguments for and against the airport but they could make up their own minds at a public forum to be held on March 11 at 7pm in the Bowman Hall on Campbell Street at Blacktown.
