The first design images of the Western Sydney International (Nancy-Bird Walton) Airport have been released.
Major earthworks will start next year that will lead to the construction of runways, roads, rail and the terminal.
Architectural team Zaha Hadid Architects and Australian Cox Architecture won the contract to design the terminal precinct beating more than 40 other entrants.
The winning design pays tribute to the western Sydney region and natural landscape.
It passed a range of value-for-money and technical reviews.
Prime Minister Scott Morrison said: "This is set to be the largest gateway to Australia and these designs are another step to making it a reality."
"Designed alongside locals and built by local workers it will deliver massive economic benefits to the region."
Mayor Mark Greenhill said he was concerned there was a terminal design but no mention of where the planes will fly.
"It's like the flight paths are in witness protection."
