Urban Infrastructure Minister Paul Fletcher says the $5.3 billion Western Sydney Airport is on track to be open by 2026.
Mr Fletcher said the airport would carry 10 million passengers a year and would generate 28,000 direct and indirect jobs within five years of its opening, notwithstanding jobs created during construction.
"This is part of a much bigger plan. The Commonwealth and NSW governments again working together on the Metro, the rail connection to the airport with a $5.25 billion Commonwealth commitment," he said.
"There's the M12 motorway which will connect to the airport. There's The Northern Road; $1.6 billion project, 35km, six stages, three of them complete.
"It's three levels of government working together to deliver jobs, deliver economic opportunity. We're not just building an airport, a rail line, or roads, we're transforming Western Sydney."
