When Australians think about Taiwan, the focus is often narrow: a distant sovereignty dispute in the Taiwan Strait, or a potential flashpoint between China and the United States. This framing understates the scale of what is at stake.
Taiwan is not a peripheral issue. It sits at the intersection of global trade, advanced technology, democratic values and regional security. What happens there will shape Australia’s prosperity, security and way of life for decades.
That is the central argument of ASPI’s new report, Taiwan Matters. The report makes a clear case: a crisis over Taiwan would not be a distant geopolitical event. It would be a systemic shock felt in Australian households, businesses and institutions within days.
The starting point is Taiwan’s global significance. Taiwan lies astride one of the world’s busiest maritime corridors, linking Northeast Asia with global markets. A disruption to shipping through the Taiwan Strait would ripple through supply chains almost immediately, driving up costs, delaying goods and creating shortages across industries.
Even more important is Taiwan’s role in advanced technology. Its semiconductor industry, led by firms such as TSMC, produces the majority of the world’s most advanced chips. These underpin modern life, from smartphones and vehicles to medical devices, artificial intelligence systems and defence equipment. Serious disruption to Taiwanese chip production would cascade across the global economy, halting manufacturing lines and constraining technological development.
The report highlights that Taiwan’s economic weight is not just about exports. It is deeply embedded in global supply chains as both a supplier and a customer. Major economies, such as the US, China, Japan and Australia, depend on Taiwanese inputs to sustain their own industries. This interdependence means that any crisis would be amplified across multiple sectors simultaneously, turning a regional contingency into a global economic shock.
Taiwan’s importance goes beyond economics. As a vibrant democracy of 23 million people, it represents a powerful counterpoint to authoritarian narratives in the region. This makes Taiwan symbolically important in the contest over the future of the international order.
The report also explores a less commonly discussed idea: Taiwan as a strategic sponge. As long as Taiwan remains separate from China, it absorbs much of Beijing’s political, military and diplomatic attention, constraining China’s ability to project power elsewhere. If Taiwan were annexed, that constraint would diminish, potentially freeing up Chinese resources for other theatres, from the South China Sea to the wider Indo-Pacific.
The consequences of a crisis would be immediate and severe. Economic modelling cited in the report suggests that even a limited disruption, such as a blockade, could significantly reduce global economic output. A full-scale conflict could trigger losses exceeding the global financial crisis and the Covid-19 pandemic.
For Australia, the impacts would be direct. Our economy is deeply tied to Indo-Pacific trade. Much of Australia’s trade flows through or is connected to Northeast Asia. A disruption in the Taiwan Strait would affect export demand, shipping routes and financial stability. Commodity exports could fall sharply, while the cost of imports, from electronics to machinery, would rise.
Supply chains would be hit hard. Australian industries, including defence, rely on advanced components that are made in or pass through Taiwan. A crisis would expose the fragility of these arrangements, leading to shortages, delays and increased costs, affecting everything from industrial production to everyday consumer goods.
The societal impacts would be just as significant. A major crisis would likely be accompanied by cyber operations and information campaigns targeting Australian institutions and public opinion. At the same time, communities with ties to Taiwan and China would feel the strain directly, through concern for family members, disrupted connections and the risk of social tension.
The report details strategic implications. A forcible change to Taiwan’s status would fundamentally alter the balance of power in the Indo-Pacific. It would weaken confidence in US security guarantees, put pressure on regional states to accommodate Beijing and reshape maritime dynamics across the Western Pacific. For Australia, this would narrow strategic options and introduce a level of insecurity.
Canberra would face hard choices. Expectations from allies, particularly the US, would likely be high, ranging from access to bases and logistical support, even potentially requests for military involvement. Meanwhile, risks of escalation, including retaliation against Australian interests, would be real.
The report does not argue that conflict is inevitable. It emphasises prevention, deterrence and resilience, but makes clear these require a much deeper level of understanding across government, industry and society.
Taiwan Matters ultimately moves the debate beyond abstract strategy and into concrete consequences. It shows how a crisis would unfold across economic, military, political and social domains and why those effects would be felt far beyond the Taiwan Strait.
For Australia, the message is clear. Taiwan is not a distant issue to be managed at the margins of policy. It is a central test of the Indo-Pacific order and a key determinant of our future security and prosperity. Raising awareness of this reality is not alarmism. It is preparedness. The alternative, treating Taiwan as someone else’s problem, risks a nasty strategic surprise.
