Notes on Defence, Foreign Affairs and Public Opinion in Australia

For most of the 20th century, except during the World Wars, defence and foreign affairs saw minimal political contestation in Australia.
This allowed for a long-standing bipartisanship in Australian politics, leading to low public interest and limited knowledge about strategic options among citizens.
Noteworthy exceptions include the Vietnam War, where political divisions emerged over support for the U.S.
Engagement in foreign policy issues notably increased after key events like the September 11 attacks and the Bali bombings in 2002.

The changing strategic environment has heightened public awareness of defence and foreign policy issues.
Australia’s military involvement in the Iraq War led to divisions among major parties and increased public scrutiny of defence policy.
Globalisation has intertwined economic considerations with defence and foreign policy, further awakening public interest.

Prior to the late 1980s, issues related to defence and foreign affairs were rarely polled, hindering longitudinal analysis of public opinion.
Introduction of the Australian Election Study (AES) in 1987 and the Lowy Institute survey in 2005 provided valuable data on public attitudes.
Systematic study of Australian public opinion on defence and foreign affairs can now be conducted.

Traditional views in political science suggest public opinions are often ill-informed and unpredictable, as argued by foreign policy realists.
In contrast, liberal perspectives see public opinion as essential for accountability and can influence foreign policy outcomes.
Recent analyses have moved toward pluralist models where public opinion is seen as logical and coherent, influenced by elite cues.

The bipartisan nature of foreign policy has occasionally stifled democratic debate, as major parties avoid contentious troop deployments.
The end of colonial ties has allowed Australia to pursue a more independent foreign policy in recent decades, highlighted by multiple free trade agreements with various countries.
There are shifts in demographic composition, with nearly half of Australians being overseas-born or having immigrant parents, impacting foreign policy attitudes.

The discussion around defence, foreign policy, and public opinion revolves around:
- Australia's engagement with Asia,
- The ANZUS alliance,
- Australia's role as an international actor.
Changes in demographic make-up influence public sentiment towards Asia, showing some key trends and generational shifts.

Various studies have indicated a connection between public opinion and perceived threats, affecting attitudes toward military alliances and interventions.
Despite bipartisan support for ANZUS, public skepticism about military interventions (like Iraq) has led to significant political debate.
The general tendency shows that while public opinion remains supportive of alliances, it is less forgiving of overseas military deployments not backed by strong political rationale.

The findings illustrate that public opinion in Australia regarding defence and foreign policy has become more engaged and complex.
Public sentiment is increasingly critical of unchallenged governmental decisions in foreign affairs, signalling a demand for more public debate in shaping policies that affect Australia’s national interests.
