WHILE many of Liverpool's leaders have spoken out in favour of the decision to build an airport at Badgerys Creek, some are still reluctant to support it.
Liverpool mayor Ned Mannoun, a Liberal, welcomed the airport commitment.
"This brings 30 years of indecision to an end," Cr Mannoun said.
"An airport at Badgerys Creek will generate a huge economic boost for both Liverpool and surrounding areas.
"The airport could bring more than 20,000 jobs to Liverpool and more than $9 billion in economic growth for western Sydney."
He said that the council would work with all levels of government to deliver the infrastructure and services that are essential to support a project of this scale.
But Liverpool Labor state MP Paul Lynch said the airport would not bring the benefits to western Sydney that the federal government was promising.
"The Abbott-Mannoun model with no curfew is a betrayal for western Sydney," Mr Lynch said.
He said he received a letter from Deputy Prime Minister Warren Truss recently which said that there would be no local operational jobs from the project for at least 10 years.
Macarthur MP Russell Matheson, a Liberal, said he wanted to see "infrastructure first, runway last".
Mr Matheson said he had put together a list of all the infrastructure that would need to accompany an airport at Badgerys Creek including an upgrade of several state-owned roads as well as new roads.
"I'm pushing hard to get the Spring Farm parkway to the Hume Highway," he said.
Mr Matheson said he would be speaking to Macarthur mayors and state MPs about what they wanted to see in terms of infrastructure and would be active in the community consultation phase.
"It still has to go through the consultation process with the community and it will need an updated environmental impact statement, we wouldn't be able to rely on the old studies" he said.
Mr Matheson said his opposition to a Badgerys Creek airport "had not changed but I've got to take a pragmatic approach to deliver the best possible outcome".
