Western Sydney Science Park has room for thousands more homes if government wants them

A science park development site four times bigger than the axed Rosehill mini-city has approval for just 3400 homes despite sitting near Western Sydneyโs new airport.
A development site near Western Sydneyโs new international airport is four times bigger than the now aborted Rosehill Gardens mini-city โ but has approval to build only a fraction of the 25,000 homes the racecourse was set to deliver.
Developers Celestino have lodged a planning application for stage one of their Sydney Science Park project at Luddenham, including a school for 1200 students and more than 200 terrace style dwellings.
Under future plans for the 271 hectare site, the park will expand into a mixed-use precinct with โknowledge-based employmentโ in health, education and research along with retail, commercial and residential zones.
Mamre Anglican School will relocate from Kemps Creek to the Sydney Science Park in Luddenham, but planning controls have restricted the park to just 3400 homes.
But planning controls have restricted Sydney Science Park to 3400 homes, despite its 3km proximity to the airport, the 12,000 jobs to be created within its boundaries, and the 20,000 employment opportunities the nearby Bradfield City is slated to generate.
Commercial and residential elements will cover just 18 per cent of a site that in its entirety dwarfs the 60-hectares for the mooted mini-city at Rosehill that was killed off when Australian Turf Club members voted down a sale of the racecourse last year.
A Celestino state significant development application has just come off exhibition.
It seeks to subdivide a small percentage of the overall site to commence the projectโs opening stage featuring the Mamre Anglican School to cater for children from kindergarten to Year 12.
Elsewhere in Sydneyโs west, state-owned developer Landcom has abandoned plans for up to 1500 homes, citing concerns over financial feasibility. Property development company ALAND has also gone public about moving to areas closer to the CBD due to shrinking profit margins.
Westpac CEO Anthony Miller has told this masthead previously that more needs to be done to deliver homes in outer suburbs to offer options in a $500,000 to $750,000 price range.
โI feel like progress has been made,โ he said this week. โBut the emphasis on getting more done in that price zip code โฆ thereโs a long way to go.โ
Celestino CEO Matthew Scard told The Daily Telegraph his company was committed to the west and had invested $100 million into Sydney Science Park since 2016 to โservice the site with sewer, water and power infrastructure to deliver housing and jobsโ.
โEven as planning controls have tightened and new development costs have been levied, we have kept faith in our vision for this new city,โ he added.
Initially rezoned for mixed-use development 10 years ago, Sydney Science Park had new controls imposed when the Aerotropolis planning framework was released in 2022. They included restrictions on where and what types of housing could be delivered, and rising contribution charges.
Construction of a new metro station next to the vacant land of the proposed Sydney Science Park in Luddenham where thousands of houses could be built near the new Western Sydney International Airport.
Asked if the company would consider applying for approvals to increase the number of dwellings on the site โ given recent market developments including Landcomโs withdrawal from projects in Tallawong, Rooty Hill and Austral โ Mr Scard was guarded.
โSydney Science Park is not a residential-only estate,โ he said.
โBut if we can provide more housing in addition to what we are doing with education, health, research and retail, then why not? The site is ready to go.
โIt has the capacity and essential services to deliver thousands more homes if the government requires additional housing in Western Sydney.โ
Planning Minister Paul Scully told the Telegraph: โThereโs a strong housing pipeline for Western Sydney with more than 10,300 homes declared state significant through the Housing Delivery Authority.
โThe NSW Government supports a mixed-use approach to development at Sydney Science Park. This is reflected under the current planning framework and controls.โ
