Previously secret NSW government documents have identified Port Kembla, located 75km south of Sydney, as the preferred east coast base for Australia's proposed nuclear submarine fleet under the AUKUS agreement. The documents, prepared by the NSW cabinet office and premier's department, warn that the facility could be a target for Australian military adversaries. Residents are expected to resist the proposal due to concerns over nuclear accident risk and the base's potential as a military target. No official site announcement has been made, with Brisbane, Newcastle and Port Kembla all previously identified as candidates.

Impact verdict

Medium impact. While currently a planning and intelligence disclosure event rather than an active incident, the identification of a future nuclear submarine base as a military target introduces significant long-term war risk and nuclear incident exposure for insurers covering the facility, surrounding infrastructure, and Port Kembla's existing industrial operations.
