SYDNEY, AAP – Sydney’s third city – to be built around the western Sydney airport – will be named after John Bradfield, the engineer who designed and oversaw construction of the Sydney Harbour Bridge and the city’s railway network.

Premier Gladys Berejiklian said Bradfield would be Australia’s “first 22nd century city”, that would deliver up to 200,000 jobs across the western parkland precinct.

“I’m very pleased that this core of the city we are building will be called Bradfield in honour of that outstanding engineer who shaped much of Sydney’s transport network, who had the vision of the Sydney Harbour Bridge and who’s inspired generations of engineers,” she said on Tuesday.

The name was chosen after extensive community consultation and endorsement by a government panel.

Located north of Bringelly, Bradfield will cover more than 100 hectares which will incorporate advanced manufacturing and be a centre for research, science and education.

The precinct will be adjacent to the Nancy Bird Walton Airport that’s now under construction, that’s due to begin operations on 2026

Standing in the paddock where the new city will be built, the premier said the area would create great economic opportunities with blossoming industries incorporating advanced manufacturing, logistics, agribusiness, research and development as well as a myriad of industries creating jobs for the future.

“As we’re going through a difficult time for our state it’s important to plan for us to plan for our future,” she said.

Memorandums of understanding had already been signed with 18 organisations, locally and globally, which were interested in establishing enterprises in the city.

People living in Sydney’s second city Parramatta would in the future be looking west to Bradfield, rather than Sydney for jobs.

“We will be competing around the world for the best jobs,” the premier said.

Western Sydney Minister Stuart Ayres said plans were under way for roads, parks and transport networks and the first building would be under construction by 2023.

The project which includes a rail link to the airport had been allocated $11 billion and there had already been extensive rezoning of land in the area, he said.

Opposition Leader Jodi McKay said residents in the area were distraught their properties had been rendered “worthless” after being rezoned, and that there had been no proper consultation or explanation and residents had been treated with contempt.

“These are people’s homes, These are people’s farms. They’ve been in families for generations, people have raised their children,” she said.

The government had compulsorily acquired about 26 hectares of land at Orchard Hills where the metro station will be built, while other residents around Bringelly had had their land rezoned and told it would eventually be bought for parkland.

“Their land is being compulsorily acquired by a government that’s not … paying them what it’s worth,” Ms McKay said.

“It’s about treating people with respect and saying ‘We’re going to properly compensate you’.”
