Australia’s prosperity runs on systems that look permanent but depend on inputs arriving from beyond its shores. While the ships keep coming, that dependence is invisible. When they stop, it becomes the only thing that matters. Yet one practical question is rarely asked: how long could a critical system keep running if the external supply were cut tomorrow? (From: The Strategist. The Australian strategic Policy Institute.
In ASPI’s latest report, Make Stuff Here… or Else, I’ve called this the ‘sovereignty countdown’. Sovereignty is a nation’s ability to make choices about how it works. The sovereignty countdown is the time a system (essential to our sovereignty) can keep operating on the reserves, substitutes and domestic capability already in hand. Every essential function has one. Water, fuel, food logistics, power and communications all run on a clock that most of their operators have never started.
Framed this way, resilience stops being a slogan and becomes an engineering problem. A nation that knows a system has 30 days of endurance can set about extending it to 90. A nation that doesn’t know the sovereign countdown is just guessing and mistaking present operation for underlying security.
The numbers are sobering. Australia owns its dams, pipes and treatment plants, yet safe drinking water depends on a narrow supply of treatment chemicals. For major cities, those buffers are often measured in weeks, sometimes as little as a fortnight. A country can own all the hardware and still lose control of its tap water if the chlorine stops arriving.
Fuel tells a similar story on a larger scale, with national diesel cover usually discussed in weeks rather than strategic depth. Fertiliser tells a slower one: interrupt urea supply during winter planting, and the damage doesn’t show until the harvest fails months later. Some countdowns run in days, others across a season, but each can be measured, managed and extended.
A countdown is not only a measure of an accident. It is also a measure of leverage. A rival does not need to engineer a crisis if it can see where Australia already runs on short buffers, single suppliers or predictable resupply windows. Pressure can then be applied at exactly the point where disruption would bite hardest and be hardest to ignore. The actor need not even be hostile. A competitor pursuing its own interests, or a trusted partner protecting its own people during a shortage, can produce the same effect. Dependence quietly becomes a bargaining chip held by someone else.
Australia didn’t lose its industrial depth through one bad decision. It lost it through thousands of rational ones. For any firm, sourcing a component offshore at a fraction of the local cost was simply good management. That logic held while global trade behaved like a neutral utility. It no longer does. Cost is a corporate measure; continuity is a sovereign one, and the two have come apart.
The government has noticed. From the 2023 Defence Strategic Review to the Future Made in Australia Act, resilience and domestic capability are now stated national priorities. But a policy can pass in a week; a refinery, a chemical plant or a skilled workforce cannot. Between the moment a country recognises a vulnerability and the moment it can fix it lies a dangerous lag, often measured in years. Australia is living inside that lag now.
Closing it starts with three steps. The first is a national resilience test: every operator of a critical system should identify the inputs it cannot run without and calculate how long it could last without them. The second is a national survival threshold, a minimum buffer below which no essential system should be allowed to operate. The third is remediation, wherever the gap is too short, through a disciplined mix of stockpiling, substitution and, where resupply would take longer than the buffer lasts, rebuilding domestic production.
This is a call to make more stuff here but not everything. Self-sufficiency in all things is neither possible nor desirable, and trusted partners, including those in AUKUS and the Quad, remain central to the picture. The test is narrower: which inputs are so critical and so slow to replace under pressure that Australia must be able to make or repair them itself.
There is an opportunity in this, not just a burden. Australia does not need to rebuild the smokestack economy of the last century. Distributed, digital and additive manufacturing can place capability closer to where it is needed across a large and thinly settled continent, an approach far better suited to the country than the vast legacy plants of the past.
Identifying a sovereignty gap is not alarmism. It is the national equivalent of fitting a smoke alarm, making a manageable danger visible before it becomes a catastrophic one. The task is finite and achievable: measure endurance honestly, set the threshold, and close the gaps that are too short. Australia should start the clock before someone else starts it for us.
