New study delays efforts to solve Sydney airport dilemma

ANOTHER study will be ordered into one of the options for Sydney's second airport, after a lengthy technical study of the Wilton site revealed several engineering and environmental challenges.

The Wilton site was one of two areas still under consideration for the second airport, the other being at Badgery's Creek.

An extensive technical study released on Friday showed the mining subsidence at the Wilton site had created challenges for any future airport proposal there.

While there were no "absolute showstoppers" to the airport being built at Wilton, a new geotechnical study will need to be completed before a Commonwealth decision.

Infrastructure Minister Anthony Albanese said while the study needed to be completed, it could contribute to delays already felt at Sydney's Kingsford-Smith Airport.

He said the issue was nationally important, because any delay at Sydney affected the entire airport network, especially in regional areas of New South Wales.

Mr Albanese said domestic travellers from regional areas and international visitors needed certainty about flights to and from Sydney, or it could begin to affect passenger numbers.

He said the new geotechnical study would be completed before the end of this year, but that any future decision on the airport would need bipartisan support.

The construction of a second major airport for Sydney could take up to a decade and, as such, would need support from both sides of the aisle in Canberra, he said.

The Federal Government has not yet announced whether it would back the Wilton or Badgery's Creek site for the second airport.
