What to expect when you’re expecting ... war: Just how prepared is Australia for the macro and micro realities of a conflict in our region?

Months later, in February 1942, Japanese bombs rained down on Darwin, shattering the long-held myth that the vast oceans surrounding the island continent would forever serve as an impenetrable moat.

For eight decades, that post-war strategic settlement, anchored by the 1951 ANZUS Treaty and a reliance on US naval hegemony guaranteed Australian security and unprecedented economic prosperity. Australia grew rich by feeding and powering the rapid industrialisation of Asia, operating under the comfortable assumption that trade and security could be neatly bifurcated.

That comfortable era has drawn to a close. Today, the Indo-Pacific is the world’s most militarised theatre. The rise of a powerful, assertive People’s Republic of China, combined with disputed maritime boundaries in the South China Sea and mounting cross-strait tensions over Taiwan, has placed Australia in a strategic pressure cooker.

Geography, once Australia’s ultimate shield, has become a high-stakes vulnerability. Should deterrence fail and kinetic conflict erupt in the Indo-Pacific, Australia will not be an isolated observer. It will be on the front lines, strategically, economically and domestically.

Lessons from the front lines in the Middle East and Europe

To understand what an Indo-Pacific war would look like for Australia, military planners in Canberra are intensely studying two contemporary laboratories of modern warfare: Ukraine and the Middle East.

VIEW ALL

The war in Ukraine has dramatically demolished several long-standing assumptions held by Western defence establishments. It has proven that high-intensity interstate conflict consumes material at a rate that rapidly exhausts peacetime stockpiles.

Precision-guided munitions, artillery shells and air defence interceptors are burned through in weeks, exposing the fragility of lean, just-in-time defence manufacturing networks. Ukraine has also highlighted the democratisation of precision strike capability through low-cost uncrewed aerial vehicles and sea drones, alongside the absolute dominance of cyber and electronic warfare on the modern battlefield.

Meanwhile, ongoing conflicts in the Middle East, particularly the disruption of Persian Gulf and Red Sea maritime trade by Houthi missile and drone strikes have demonstrated the fragility of global shipping chokepoints. A relatively modest arsenal of asymmetric weapons managed to force major container lines to reroute around Africa’s Cape of Good Hope, sending global freight rates soaring, delaying supply chains and reigniting inflationary pressures across the globe.

Multiplied across the Indo-Pacific, these dynamics become existential. A conflict over Taiwan or in the South China Sea would not be contained to a single land border or maritime strait; it would instantly snarl the world’s most critical sea lines of communication. Modern warfare has shown that economic coercion, cyber attacks and infrastructure disruption occur long before the first missile is fired, a grey-zone reality for which Australia must urgently prepare.

Strategic imperatives: The view from Canberra to Darwin

At the macro level, an Indo-Pacific conflict would instantly trigger Australia’s alliance commitments. Under the ANZUS banner and the AUKUS framework, Australia’s integration into US operational planning means neutral stance options are largely theoretical. Northern Australia, stretching from RAAF Base Tindal and Darwin down to the submarine bases at Rockingham in Western Australia would function as a vital staging ground, logistics hub and strike platform for allied forces.

This operational utility makes northern Australian infrastructure an immediate high-value target for adversary long-range strike capabilities. Modern hypersonic and cruise missiles launched from naval platforms or bombers in the deep Pacific render the northern coastline vulnerable to precision targeting and electronic blindness.

The strategic imperative for Defence is no longer merely projecting force abroad but defending the sovereign homeland against long-range interdiction and grey-zone sabotage.

At the micro level, strategic strain would manifest across Australian communities overnight. Defence Force recruiting, already battling chronic shortfalls, would face intense pressure as mobilisation demands scale up. Local police and intelligence services would be deployed to protect domestic critical infrastructure power stations, subsea telecommunications cables, ports and water treatment facilities against state-sponsored cyber assaults.

Citizens in northern cities like Darwin or Townsville would experience a heightened military footprint, airspace restrictions and visible civil defence preparations not seen in 80 years.

Economic shockwaves: Macro to micro implications and fallout

Undoubtedly, the economic fallout of any major Indo-Pacific conflict would dwarf the 2008 Global Financial Crisis and the disruptions of the COVID-19 pandemic combined, with the Australian economy particularly vulnerable to the first, second and third-order effects that would ensue.

Australia’s economic model relies almost entirely on unhindered maritime trade. China remains Australia’s largest trading partner, purchasing roughly a third of all Australian exports, including iron ore, liquefied natural gas, lithium and agricultural produce. In the event of armed conflict involving the United States and China, bilateral trade would instantly collapse under the weight of naval blockades, sanctions and war-risk insurance cancellations.

• Trade interdiction: Over 90 per cent of Australia’s liquid fuel and a vast majority of manufactured goods pass through Indo-Pacific maritime chokepoints, such as the Malacca, Sunda, and Lombok straits. Any conflict that freezes shipping in these passages effectively severs Australia’s trade arteries.
• Capital and currency flight: The Australian dollar, traditionally traded as a high-beta commodity currency, would experience severe downward pressure as global investors scramble for safe-haven assets. The Australian Securities Exchange would face sharp sell-offs, particularly across banking, mining and retail sectors reliant on regional stability.
• Sovereign debt and inflation: Government spending on emergency defence, fuel subsidies and economic stabilisation would surge, forcing national debt to record levels while supply-driven inflation spiked.

At the individual or micro level for average Australian households, macro shocks would quickly translate into immediate, practical hardship, rapidly dwarfing the implications of the cost-of-living crisis currently being endured by Australians, across every aspect of their day-to-day lives.

• The fuel crisis: Despite recent federal investments aimed at boosting Australia’s liquid fuel security, such as the establishment of a government-backed national diesel reserve targeting roughly 50 days of domestic supply, Australia remains structurally exposed. If tanker routes are disrupted, strict fuel rationing would likely be implemented within weeks. Priority would be given to emergency services, agriculture and military logistics, leaving ordinary motorists facing long queues, strict caps or empty bowsers.
• Supermarket bare shelves: Australia’s domestic freight network relies almost entirely on road transport driven by diesel engines. A fuel crunch, paired with the interruption of imported components and fertilisers, would disrupt the national “just-in-time” supply chain. Supermarket shelves in suburban Sydney, Melbourne or regional hubs could empty of key staples within days.
• Job losses and mortgage stress: Sectors heavily dependent on Asian trade, such as iron ore mining in the Pilbara, agricultural exports in Queensland and international education in university precincts, would face immediate contractions, triggering widespread lay-offs. Compounded by inflation-driven interest rate pressures, household mortgage stress would reach unprecedented levels.

Sociopolitical fallout

Equally, conflict in Australia’s immediate neighbourhood would subject the nation’s political institutions and indeed the broader social cohesion, framework and the concept of “multicultural” modern Australia to extraordinary stress.

In Canberra, party politics would yield to crisis governance. The National Security Committee of Cabinet would effectively operate as a war cabinet, exercising centralised executive authority. Federal Parliament would be called upon to pass emergency powers legislation, granting the Commonwealth sweeping controls over resource allocation, fuel distribution, telecommunications and national logistics.

Maintaining bipartisan unity would prove challenging as the war’s duration and costs mount. While major political parties broadly align on the necessity of the US alliance and sovereign defence spending, fierce parliamentary debates would inevitably erupt over the extent of Australia’s military involvement, war aims and diplomatic pathways toward de-escalation.

Furthermore, Australia would become a prime target for foreign state-sponsored information operations designed to erode public resolve, trigger political paralysis, and exploit existing societal fault lines.

On Australia’s streets, the conflict would test community cohesion. Australia is one of the world’s most successful multicultural nations, home to vibrant diaspora communities from across Asia, including over 1.4 million people of Chinese ancestry and a growing Taiwanese diaspora, but this becomes more complicated if the conflict emerges on the Indian subcontinent, which would undoubtedly see the Indian, Pakistani and Bangladeshi diaspora take to the street in running street battles.

• Social cohesion under strain: During periods of international crisis, diaspora communities often face unfair suspicion, rising xenophobia or covert pressure from foreign state actors seeking to influence local debate. Political leaders would need to balance national security vigilance with firm protections for democratic freedoms and social harmony, preventing suspicion from harming peaceful citizens.
• Civil liberties v security: Expanded government surveillance powers, stricter official secrecy laws and potential restrictions on public assembly would stir concern among civil liberties groups. Australians, accustomed to individual freedom and lifestyle comfort, would be forced to navigate a wartime posture defined by curfews, digital security checks and resource conservation.
• Shifting public expectations: Public sentiment would undergo a rapid realignment. Everyday policy debates over housing affordability, climate targets or tax reform would be overshadowed by existential concerns over national defence, energy independence and household survival.

Each of these factors are issues that, even just two decades ago, would have been considered unthinkable to contemporary Australians but have rapidly become the “new normal” that Australians and our policymakers are not only going to have to accept but also confront and respond to should the unthinkable happen in our region.

Navigating the unthinkable

Australia can no longer view major conflict in the Indo-Pacific as a distant possibility or an abstract scenario confined to wargame exercises in Canberra think tanks. The lessons of Ukraine and the Middle East demonstrate that contemporary warfare is all-encompassing, blurring the lines between military front lines and civilian backyards.

If conflict erupts in Australia’s region, the nation will face a severe test of its national resilience. The macro shocks, lost export markets, alliance commitments and strategic vulnerability will be felt in every regional township and suburban street through fuel shortages, supply disruptions and economic strain.

Preparing for such a contingency requires more than acquiring advanced military platforms or expanding fuel reserves to 50 days. It demands an honest, transparent public conversation about the true costs of regional instability, sustained investment in domestic sovereign manufacturing, robust protection of social cohesion and a clear-eyed focus on deterrence.

Australia’s security no longer rests on the illusion of geographic isolation, but on its preparedness, self-reliance and national unity when tested.
