New South Wales Premier Mike Baird has announced all 1,800 Education Department jobs will be moved from Sydney's CBD to Parramatta.

Staff will move to Parramatta from the Bridge Street office in 2018, and from the Oxford Street office in 2020.

"Western Sydney is the economic powerhouse of NSW and the NSW Government is doing everything possible to further strengthen this dynamic region," Mr Baird said.

"The relocation of these 1,800 jobs will provide another massive boost to the western Sydney economy and further cement Parramatta's position as Sydney's second CBD.

"This move will provide even more opportunities for western Sydney residents to work closer to where they live, which will reduce congestion across the city."

Labor leader Luke Foley said he would believe the move when he saw it.

"Two years ago this Government promised to relocate seven of their agencies involving 3,000 employees to western Sydney – not one of those seven agencies has relocated to western Sydney.

"So today's announcement must be seen in that light – there's a lot of rhetoric from this Government but when your record is promise seven and deliver none it's hard to believe them."

The Premier's office said as of August this year, it had moved 1,012 full-time positions from government departments in city offices to western Sydney.

Western Sydney director of the Sydney Business Chamber David Borger said today's announcement was good news.

"The challenge for western Sydney is there are 300,000 people every day who leave their area to get to work, so creating jobs close to home really does make sense," he said.

"There's been 30 years of decentralisation and Parramatta is actually the best example in Australia; it's worked really well."

Report calls for 15-minute express train to city

The announcement comes as western Sydney businesses release their "wish list" for the area, designed to support the generation of 200,000 extra jobs by 2020.

The report, compiled by Deloitte Access Economics, contains 130 recommendations, including the creation of a 15-minute express train service between Parramatta and Sydney CBD.

It was compiled with the input of hundreds of Western Sydney businesses to drive investment in key job growth areas.

Report author Theo Psychogios said better transport was a major factor.

"Especially with the introduction of the airport in the decade to come, it is really quite critical," Mr Psychogios said.

"We're reducing productivity by having so many people in motion each day just to get to their desks to start their day."

He said the 15-minute train proposal was centred around recognising the parts of Sydney which would be the job centres of the future.

"While connecting workers to the city is important now it's also about working towards reversing the trend and focusing on where the jobs growth will start to mature in the next two or three decades."

The report also called for the establishment of a new western Sydney development authority to drive investment in key job growth areas in western Sydney.

Mr Psychogios said the authority would be a new body which would aim to streamline approval processes to remove duplication.

"This is not just about driving construction, whether it's residential or commercial, but that there is a real jobs focus in doing so," he said.

Another proposal was the creation of the nation's first high school specialising in science, technology, engineering and maths skills to be built in Sydney Science park, near the new Badgerys Creek airport.

"It's about recognising the skills required for the jobs of the future will be built around technology," he said.

"What we recognise is many of the students today haven't been given the opportunity to have these more technical skills."
