Mirvac and Australian Retirement Trust (ART) announced the launch of the first stage of SEED, their co‑owned, 39-hectare industrial and enterprise precinct in the Western Sydney Aerotropolis, together with the first State Significant Development approval (SSDA) from the New South Wales (NSW) Government for the transformative new precinct.
The project will provide a major economic boost for the region, with more than 3,000 jobs to be created across the two stages of the precinct’s development — spanning both construction and long‑term operational employment as SEED evolves into a major employment hub for Western Sydney.
This marks the third industrial project by the Mirvac–ART partnership, following Aspect Industrial Estate at Kemps Creek, which was the first site approved under the Mamre Road Precinct planning controls regime and is now a major employment precinct for Western Sydney. The partnership has also delivered Switchyard, a next-generation industrial estate in Auburn.
SEED will comprise 90 hectares of developable land adjoining 42 hectares of natural open space across two stages, delivering a future‑focused, sustainable and flexible employment precinct located just 800 metres from the soon to open Western Sydney International (Nancy‑Bird Walton) Airport.
With flexible warehouse opportunities ranging from 2,500 to 100,000 square metres across 17 future buildings, SEED is designed to support a diverse range of customers — from logistics and advanced manufacturing to technology, aviation‑linked enterprises and emerging industries.
Richard Seddon, CEO – Investment, Mirvac, said: “We’re proud to be extending our partnership with ART, with SEED building on the strong momentum we’ve established through Aspect and underscores our shared commitment to deliver world‑class, sustainable industrial precincts for Western Sydney. To date, we have already received strong enquiry from prospective tenants who are drawn to the location, being next to Sydney’s only 24-hour airport and the soon to be completed M12 Motorway. SEED will give customers the connectivity, capacity and confidence to scale in line with the region’s growth.”
The central outer west industrial region continues to be the powerhouse of Sydney’s industrial leasing market, accounting for 50 per cent or more of total activity. Notably, vacancy rates in this region remain well below the broader Sydney average (2.6 per cent compared to 3.6 per cent Sydney metro average)1.
Michael Weaver, General Manager, Mid Risk Assets, Australian Retirement Trust, said: “ART is proud to continue our partnership with Mirvac on SEED. This project will contribute to Western Sydney’s economic development and create jobs while targeting strong, long‑term outcomes for our members’ retirement savings.”
Stuart Penklis, CEO – Development, Mirvac, said: “We’ve worked closely with NSW Government to receive this SSDA approval providing us with the opportunity to develop this major employment hub for this growing region. We are actively advancing our $2.4bn industrial development pipeline which is 100% weighted to prime Sydney locations. We continue to leverage our asset creation capability to deliver quality, highly functional facilities with superior sustainability features and low operating costs that resonate with the current and future needs of our customers.”
The approved first stage of SEED includes premium warehouse facilities featuring:
- High‑clearance, flexible warehouse design;
- High power provisions, and secure 24/7 operations;
- Connections to high-capacity infrastructure;
- Premium end‑of‑trip facilities, an estate café and outdoor breakout areas;
- Walking and running tracks connected with the Wianamatta Creek corridor.
Mr Seddon said: “Sustainability is embedded from the ground up, with the SEED development targeting certification of net positive embodied carbon, minimum 5‑Star Green Star certification, rooftop solar, LED lighting, recycled water systems, electric vehicle charging and environmental monitoring — supporting customer ESG outcomes and Mirvac’s broader planet‑positive ambitions”.
From the inception of the project in 2018, the Mirvac team worked closely with Dharug knowledge holders to ensure SEED embraces its connection to Country, drawing on the cultural and environmental significance of Wianamatta Creek. The design approach incorporates themes of people and culture (Wianamattagal), water (Wianamatta), earth (Nura), and flora (Dirang and Daramu).
“This country has been shaped and maintained by the Dharug people for thousands of years. The vision for SEED was to lead with a Connection with Country and landscape led approach throughout the entire project, whilst also creating a best-in-class sustainable enterprise precinct by honouring the strong connection to the surrounds of the Wianamatta Creek,” said Mr Penklis.
Located on Elizabeth Drive with direct access to the M12 Motorway and close proximity to the M7, SEED connects occupiers to major road, rail and future aviation networks.
