National Security Office Precinct

For the latest news about the National Security Office Precinct, see Project Updates.

The Department of Finance is leading the development of a National Security Office Precinct (the Precinct) at York Park in Barton, ACT. The Precinct will provide a permanent solution to the critical accommodation and capability requirements of several national security and other Commonwealth agencies.

York Park (Block 5, Section 1) is a prominent Commonwealth owned site within Barton, previously used as a temporary car park. The site is bounded by Brisbane Avenue, State Circle, the York Park Oak Plantation and Windsor Walk. This site was chosen for the National Security Office Precinct by the Department of Finance in consultation with the National Capital Authority.

Consistent with the requirements of the National Capital Plan (NCP), the precinct approach will maximise the development potential of the site by addressing multiple accommodation requirements.

The Precinct and associated infrastructure will have a number of public and private tenants and is expected to be utilised by a range of Commonwealth entities including the Office of National Intelligence and parts of the Department of Foreign Affairs and Trade. The Precinct is expected to accommodate up to 5,000 workers, and will include hospitality and retail amenities servicing both the Precinct occupants and wider public.

As an enabling project to the Precinct's development, a multi-level car park was constructed adjacent to the John Gorton Building in Parkes, ACT (referred to as the John Gorton Campus Car Park).

The John Gorton Campus Car Park replaces displaced car parking by providing over 1,000 spaces in the multi-level structure to support worker and visitor amenity in the area.

The Car Park supports the objectives of the John Gorton Campus as set out in the NCP, and is planned to include a childcare centre and electric vehicle charging stations.

The former John Gorton East on-grade car park was closed on 17 July 2023, to allow for the construction of the new John Gorton Campus Car Park which was opened on 12 February 2025. See the John Gorton Campus Car Park - Fact Sheet for further details about access to the car park.

To minimise disruptions in the area, the project development has been staged:

• Stage 1: John Gorton Campus Car Park – Construction commenced on 17 July 2023 and opened on 12 February 2025 (landscaping and concrete façade elements will continue throughout 2025).
• Stage 2: National Security Office Precinct – Early site works commenced at the National Security Office Precinct in late 2024. Staged closure of Windsor Walk and York Park Car Parks occurred in January 2025, and the site closed permanently on 12 February 2025. Construction works are underway.
