Leaked plans suggest Sydney's second airport at Badgerys Creek will eclipse Sydney Airport at Mascot, with work to begin as soon as next year.
Confidential maps obtained by News Corp showing the planned site, runway and terminal locations reveal an airport that could eventually rival New York's JFK International Airport for capacity and size.
A site map for "stage 1" includes a 3700m east-west runway, a domestic, international and cargo terminal, and a tunnel earmarked for a future underground rail link to the airport.
It would take eight years to build and take 10 million passengers annually at a cost of $4 billion, News Corp reports.
By 2050, a second 3700m runway would be complete, with the airport forecast to take 80 million passengers annually - about twice the number presently serviced by Sydney Airport at Mascot.
Mass excavation work is expected to generate several thousand jobs, with work reportedly to begin by the middle of next year.
The maps were reportedly drawn up by commercial contractors and provided to the Abbott government in February.
