Australians’ Rising Concern Over National Security

A recent study by the Australian National University's National Security College has shed light on the growing concern among Australians regarding national security. The report, based on polling and focus groups, indicates that almost half of Australians believe a foreign military attack on the country is likely within the next five years.

The study, conducted between November 2024 and February 2026, found that two-thirds of those polled were worried about various security issues. The sharpest increase in concern was observed among the 18-24 age group, with 55% expressing anxiety about national security, up from 22% in November 2024.

Australians' fears encompass a range of threats, including AI-enabled attacks, disinformation, supply disruptions, climate change impacts, foreign interference, and economic crises. These concerns are heightened by Australia's involvement in overseas military conflicts, with 69% of respondents in July 2025 considering it likely or almost certain.

The study's findings suggest a growing sense of vulnerability among Australians, with 45% considering an onshore attack by a foreign military as likely or almost certain within five years. This perceived threat is considered the most concerning, with potential major consequences, according to respondents.

Furthermore, the study reveals that Australians believe the country is ill-prepared to handle these threats. Over half of those surveyed felt Australia was slightly prepared or not at all for various security challenges, including foreign attacks and economic crises.

The report's release coincides with the latest Middle East war, which has disrupted global fuel supplies and impacted Australia's energy sector. Federal Energy Minister Chris Bowen confirmed the cancellation or deferral of six oil ships bound for Australia, highlighting the real-world implications of these security concerns.

This study underscores the importance of addressing national security issues and ensuring Australia is equipped to handle potential threats, as the country navigates an increasingly complex global landscape.
