FEDERAL cabinet could sign off on an airport at Badgerys Creek this week, with reports the government will release a $200 million transport infrastructure package to support the project.
Western Sydney Airport Alliance spokesman David Borger said building roads to connect residents to the airport would be a fairly low-cost operation as land around the Badgerys Creek site was relatively undeveloped.
"Connecting [the airport] to the close-by South West Rail Link and M7 Motorway will be an absolute bargain basement deal for Sydney," he said.
Since the likelihood of the the government's plan to give Badgerys Creek the nod was announced in metropolitan media last week, hopes that the airport could provide more jobs and a bigger share of tourist dollars for western Sydney have risen.
"Airports are one of the only pieces of transport infrastructure that generate more jobs in operation than during construction," a Department of Infrastructure and Regional Development spokesman said.
"These range from aircraft maintenance engineers, airline staff and baggage handlers to customer service, retail and logistics staff.
"There will be a large number of good trade jobs with the construction phase [and] an ongoing need for tradespeople to keep the airport running."
Analysis by the department in 2013 found that if a full-scale airport was built at Badgerys Creek, jobs could increase, with population growth, to more than 60,000.
The spokesman said passenger volume and businesses moving their operations would influence the number of jobs on offer.
