Australia's Semiconductor Gap Costs Billions as Chip Manufacturing Clusters in Asia

Australia is a world leader in semiconductor design. We create the blueprints for chips that power everything from smartphones to mining equipment. Yet we manufacture almost none of them. Instead, we ship designs overseas, wait for factories in Taiwan, South Korea and Japan to build them, then import the finished chips back. This gap in the middle costs Australian businesses billions in lost opportunity, delayed supply, and vulnerability to distant disruptions.

Why chip factories cluster in one region

Building a semiconductor fabrication plant (or 'fab') is the most expensive industrial undertaking on Earth. A modern fab costs between $10 billion and $20 billion to construct. It requires extreme precision: manufacturing happens in rooms cleaner than an operating theatre, where a single dust particle can ruin a wafer of chips worth hundreds of thousands of dollars. The process demands expertise, reliable electricity, ultra-pure water, and stable political conditions.

These conditions exist in Taiwan, South Korea, Japan and increasingly China. Taiwan alone manufactures over half the world's advanced semiconductors. South Korea dominates memory chips. Japan specialises in specialised and legacy chips. This concentration happened because early winners attracted investment, skilled workers clustered there, and governments backed the industry with subsidies and research funding. Once momentum builds, moving a fab elsewhere becomes enormously expensive.

Australia's design strength and manufacturing weakness

Australia excels at the creative work. Engineers in Sydney and Melbourne design chips for artificial intelligence, automotive systems, radio-frequency communications, and power management. Companies like Technoology and smaller specialists punch well above their weight globally. The design phase is high-value, low-cost work: talented engineers, good universities, and proximity to Asian markets make Australia competitive.

Manufacturing is the opposite. Australia has no modern commercial fab. We have research facilities and legacy plants, but nothing that can compete with Taiwan or South Korea on cost, scale, or capability. A designer must either partner with a foreign foundry or accept long lead times and higher costs. During global chip shortages-like the one that paralysed car production in 2021 and 2022-Australian design companies were helpless. Their fabs were booked out for months. Competitors with established relationships got priority.

The geopolitical squeeze

The concentration of chip manufacturing in Asia creates strategic risk. Taiwan produces the majority of the world's most advanced chips. If tensions across the Taiwan Strait escalate, global chip supply could collapse within weeks. Japan and South Korea would be overwhelmed. The United States, European Union, and other democracies have recognised this vulnerability. They are now spending tens of billions of dollars to build new fabs domestically-efforts that may take a decade to yield results.

Australia has discussed building a fab but has not committed serious capital. Instead, we rely on diplomatic relationships with Japan and South Korea to secure chip supply during crises. This works for now, but leaves us dependent on goodwill rather than capability.

What it means for Australia

The chip manufacturing gap affects Australia across three dimensions. First, we lose direct jobs and investment. Every fab built in Taiwan or South Korea is billions in revenue and thousands of jobs that might otherwise go to Australian workers. Second, Australian chip designers must accept longer timelines and higher costs. A startup cannot build a product quickly if it must queue for overseas manufacturing. Third, our defence and critical infrastructure-power grids, telecommunications, defence systems-depend on chips we cannot make ourselves. A supply shock hits us harder than countries with domestic capacity.

Agriculture, mining, and advanced manufacturing all depend on semiconductors. As these industries become more digital and automated, the gap widens. A Tasmanian precision agriculture company cannot innovate as fast as a competitor in California with instant access to a nearby fab.

The bottom line

Australia is not alone in this position. Most countries outside East Asia face the same constraint. But the gap between design excellence and manufacturing capacity represents lost growth. Building an Australian fab would be extraordinarily expensive and take years to become productive. A more realistic path involves incentivising Japanese or South Korean manufacturers to build satellite facilities here, investing in research partnerships, and securing long-term supply agreements with Taiwan and South Korea. Until that happens, Australia designs the future but manufactures it overseas.
