The Federal Government has signalled that a second airport for Sydney would operate 24 hours a day, indicating the airport will be built at Badgery's Creek and would be operating inside of 15 years.
"A number of people have suggested alternatives (to Badgery's Creek) but all of them seem to have problems" Deputy Prime Minister Warren Truss said in an interview with ABC TV's 7.30 program overnight.
"It was the site that was chosen a long time ago and it is still obviously the frontrunner. There's no perfect site for a second airport."
A final decision is expected to be made early next year, although the site is already earmarked on Google Maps as Sydney West Airport and has been allocated the airport code of SWZ.
Truss also indicated the new airport would operate 24 hours a day, compared to the current 11pm to 6am curfew imposed by Sydney Airport on international flights.
"If Sydney is to be a world-class city … a city that is going to be able to compete internationally, then it will have to have airport services that are available 24 hours" Truss said.
''There's no doubt that Sydney loses a lot of the economic benefit of its airport because it is only operating limited hours. There are a number of movements out of Melbourne and Brisbane that happen in hours when there is no airport open in Sydney."
Truss also stated that a second airport for Sydney should be running before the 2027 target date nominated by the Western Sydney Alliance group which is promoting Badgery's Creek.
'I am confident that an airport could be built and operating well and truly before the target date set by the alliance" Truss said. ''You'd start modestly and then build up the facilities once the traffic movements justify it.'"
