Australian Government commissions AECOM for Henderson Defence Precinct site characterisation studies in Western Australia

Executive Summary

The Australian Department of Defence announced on May 27, 2026 the appointment of AECOM Australia to conduct environmental and ground studies across the Cockburn Sound region. The engagement lays the foundational infrastructure planning basis for the Henderson Defence Precinct in Western Australia.

Key Regulatory Signals

Contract Award: AECOM Australia has been appointed to deliver site characterisation studies covering environmental, ground, and marine conditions across the Cockburn Sound region adjacent to Henderson.
Scope of Studies: Work encompasses environmental and geotechnical assessments of the site, surrounding waters, and broader environment — standard precursors to major defence infrastructure procurement.
Precinct Development Stage: The appointment represents a pre-construction planning phase. No construction contract, funding envelope, or delivery timeline has been publicly stated in this release.
Strategic Location: Henderson, Western Australia hosts existing naval and defence industry facilities, including the Australian Marine Complex, positioning the precinct within an established sovereign industrial base.

Regulatory Delta

- The Henderson Defence Precinct aligns with the 2024 National Defence Strategy and Integrated Investment Program, which identified Henderson as a priority site for enhanced naval and defence industrial capacity. - This appointment marks the formal transition from policy commitment to site-level technical investigation, preceding any infrastructure procurement or environmental approval process. - The Department of Defence's engagement of AECOM follows the broader AUKUS Pillar II industrial base expansion agenda, under which Western Australia has been designated a key node for future naval sustainment and construction capability.

Materiality Classification
