A SECOND airport site at Wilton to the south-west of Sydney would not work and governments need to start planning for a site at Badgerys Creek, according to the aviation and tourism industries.
The latest call to revive planning for a Badgerys Creek airport comes from the Tourism and Transport Forum, whose members include Sydney Airport, which has repeatedly argued another Sydney airport is not necessary.
But the forum, whose message comes on top of strong business support for a western Sydney airport, argues that short-term measures will not be enough to negate the need for another major airport in a city where demand for air travel is expected to double in the next 20 years.
''It's a process of elimination,'' the chief executive of the forum, John Lee, said.
''People can flag any other type of airport solution but Badgerys was arrived at 20 years ago for good reason,'' he said.
''There is definitely momentum politically around the economic value of a second airport in Sydney.''
The forum report, Sydney's Aviation Future: Meeting the Challenge of Growing Demand, released on Tuesday, says concerns about noise pollution in the western suburbs from a Badgerys Creek airport could be offset by the proper planning of runways, using parallel runways, rather than crossed ones.
