Announced last observed as of 2026-08-31 · Project announcement

The consultant's SEARs request (letter dated 6 March 2026, ref WTJ25-464; 36 pages) seeks SEARs under the Rapid Assessment Framework for a State significant development application for a new data centre 'to be known as the Mars Road Data Centre' on Lot 8 DP241877 (3 Apollo Place, 3,473.3 m2), Lot 9 DP241877 (4 Apollo Place, 1,289.5 m2), Lot 100 DP622160 (87 Mars Road, 2,428.2 m2) and Lot 1 DP732557 (91 Mars Road, 7,852.9 m2), plus part of Lot 1 DP1271404 (1 Sirius Road, which holds the Lane Cove West Data Centre SSD-9741 and Apollo Place Data Centre SSD-67407231 approvals). It proposes demolition, consolidation of the four lots, and a five-storey data centre with roof plant, about 13,800 m2 GFA, 37.4 m high, total IT load about 140 MW, about 120 back-up generators, diesel and lithium-battery storage and two driveways (site about 15,044 m2). It states that 1 Sirius Road will not form part of the site when the EIS is lodged (boundary adjustment and consolidation into a single lot) and that 'Future development proposed on the Site will operate independently to both the Lane Cove West and Apollo Place Data Centres.' The proponent table names only the planning consultant; no developer or operator is identified. evidence

The Department's 9 April 2026 letter issues the SEARs for the Mars Road Data Centre State significant development application (SSD-108835458) to the applicant's planning consultant. It asks the applicant to refine the substantial development footprint so that direct impacts on vegetation within 1 Sirius Road, which is subject to restorative works and maintenance requirements under the separate consent SSD-9741, are avoided. evidence
