Nearly Half of Australians Believe a Foreign Military Will Attack Within Five Years

ANU study finds sharpest rise in national security anxiety among 18 to 24 year olds as Middle East war reshapes threat perceptions

Nearly half of Australians believe a foreign military will attack the country within five years, according to a new study from the Australian National University's National Security College. The report found that two-thirds of those polled in 2026 were worried about national security issues, with the sharpest increase in anxiety among young adults aged 18 to 24.

The findings reflect a dramatic shift in public sentiment driven by the ongoing Middle East conflict, the oil shock that has disrupted Australian daily life, and broader geopolitical instability including tensions with China and the US alliance dynamics under the Trump administration.

The study used a combination of representative polling and focus groups to measure attitudes toward national security. The results suggest that the abstract concept of military threat has become concrete for many Australians, particularly younger people who have watched fuel shortages and economic disruption flow directly from distant conflicts.

The government's decision to decline US requests to send warships to the Strait of Hormuz appears to have heightened rather than eased public concern, with some respondents expressing worry that Australia is isolated without strong alliance commitments.

Defence analysts note that while an actual military attack on Australia remains highly unlikely, the perception of vulnerability has real policy consequences, potentially driving increased defence spending and changing attitudes toward military alliances.

Analysis

Why This Matters

Public perception of military threat drives defence policy and spending. If nearly half the population believes an attack is imminent, that creates political pressure for significant shifts in national security posture.

Background

Australia has traditionally felt insulated from direct military threat by geography and alliances. The Iran war and its economic knock-on effects have challenged that assumption for many citizens.

Key Perspectives

Defence experts stress that the threat perception gap between public fear and actual military risk is significant. However, the psychological impact of fuel shortages and economic disruption has made abstract threats feel tangible.

What to Watch

Whether these attitudes translate into bipartisan support for accelerated defence spending and AUKUS implementation ahead of the federal election.
