The federal government predicts a jobs boom associated with Sydney's second airport at Badgerys Creek will result in a new city in the west.
Federal Assistant Cities Minister Angus Taylor is expected to tell a summit at Parramatta that a "city deal" between the Commonwealth, NSW and eight local governments will transform the lives of western Sydney's two million residents.
The aim is "to build an aerotropolis offering tens of thousands of jobs, to deliver reform to planning laws to free up more housing supply, and to get roads and rail infrastructure built faster," Mr Taylor will tell the Out There Summit on Friday.
His speech is expected to highlight the "jobs gap" in western Sydney, with a third of employees travelling outside the area for work each day.
"The western Sydney Airport will be a once-in-a-generation opportunity for new jobs and long-term growth, which will support the emerging western city as a thriving CBD," Mr Taylor will tell the conference.
The government says the second airport is expected to generate nearly 9000 jobs by the early 2030s and 60,000 jobs long-term.
Thousands more jobs are expected to flow from businesses attracted by the airport, with universities and the aviation, defence and logistical industries already eyeing off the area.
Mr Taylor is expected to reaffirm the Commonwealth's pledge to ensure the airport is up and running by 2026.
