The new city will be home to research, science and education facilities as part of the first stage of the Aerotropolis Core precinct.
The city stretches over 100 hectares of land and will be a key driver for Greater Sydney's economic growth, jobs and opportunities for generations to come.
The precinct will connect Liverpool, Penrith and Campbelltown and expand on the network of roads and public transport.
Local community members are encouraged to come up with names that reflect NSW’s heritage, recognise people who have contributed to the state, or honour figures connected to Western Sydney.
Premier Gladys Berejiklian said the naming process to be carried out will find a unique name which will forever define Australia’s first 22nd Century City.
“Until now we have been referring to the area as the Aerotropolis Core, but with the city quickly moving from a vision to a reality now is the time for it to be given a real place name,” Ms Berejiklian said.
