Ukraine's Lessons for Australia: Asymmetric Warfare and Deterrence (2026)

The Winter Is Coming for Australia: Lessons from Ukraine and the Indo-Pacific

There’s a chilling phrase that’s been echoing through the halls of Australian defense circles lately: “Winter is coming.” It’s not just a nod to Game of Thrones—it’s a stark warning from Air Marshal Stephen Chappell, the head of the Royal Australian Air Force, about the deteriorating security landscape in the Indo-Pacific. Personally, I think this metaphor is more than just a catchy line; it’s a wake-up call. What makes this particularly fascinating is how it frames the region’s challenges—not as distant threats, but as an approaching storm that demands immediate action.

The Looming Shadow of a Modern War

One thing that immediately stands out is the blunt assessment from Lieutenant General Susan Coyle, the incoming army chief. She calls it “delusional” to think Australia’s current defense capabilities could withstand a modern conflict. In my opinion, this isn’t just a critique of the Australian Defense Force (ADF); it’s a broader commentary on how rapidly warfare is evolving. What many people don’t realize is that the nature of war hasn’t fundamentally changed—it’s still about violence and conflict—but technology has transformed the battlefield. From degraded satellite communications to manipulated missile systems, the ADF’s vulnerabilities are glaring.

This raises a deeper question: How can Australia prepare for a war it’s not equipped to fight? Coyle’s answer is clear: rapid transformation. The ADF, she says, will be unrecognizable in five years. But here’s the kicker—will that be enough? If you take a step back and think about it, the pace of technological advancement in warfare is outstripping even the most ambitious defense reforms.

Nuclear Subs: A Game-Changer or a Distraction?

Vice Admiral Mark Hammond argues that AUKUS nuclear submarines will be pivotal in deterring regional threats. What this really suggests is that Australia is betting big on a single capability to counter a complex, multi-faceted challenge. A detail that I find especially interesting is the historical precedent Hammond cites—nuclear subs have only been deployed twice in combat, both times with devastating effect. But here’s the thing: the Indo-Pacific isn’t the Falklands or the Persian Gulf. The region’s dynamics are far more intricate, with China’s military modernization posing a unique threat.

From my perspective, relying solely on nuclear subs feels like putting all your eggs in one basket. What happens if China targets Australia’s critical infrastructure with cyberattacks or long-range missiles, as experts warn? The Lowy Institute’s prediction that previously out-of-reach areas in Australia could become fair game within a decade is particularly alarming. This isn’t just about naval dominance—it’s about a comprehensive defense strategy that Australia seems to lack.

Ukraine’s Asymmetric Warfare: A Blueprint for Australia?

Ukraine’s ambassador to Australia, Vasyl Myroshnychenko, offers a compelling perspective: Australia should look to Ukraine’s war for lessons. What makes this particularly fascinating is the emphasis on asymmetric warfare. Ukraine, with its relatively small army, has managed to hold off Russia through innovation and adaptability. Myroshnychenko points out that Ukraine’s drones and missiles, developed at a fraction of the cost of conventional weapons, have been game-changers.

But here’s where it gets interesting: Ukraine’s success isn’t just about technology—it’s about the speed of innovation. The cycle from battlefield to manufacturing and back is lightning-fast. Personally, I think this is a lesson Australia can’t afford to ignore. If Australia were to face a larger, more technologically advanced adversary, it would need to adopt a similar mindset. The question is, can Australia’s defense industry scale up fast enough?

The Hidden Threat: Drones in Shipping Containers

One of the most striking insights from Myroshnychenko is the threat of drones hidden in shipping containers. Imagine this: an enemy secretly delivers a container full of drones to an Australian port, only to activate them once they’re on shore. This isn’t science fiction—it’s a very real possibility. What many people don’t realize is that this kind of asymmetric attack could cripple critical infrastructure before a single missile is fired.

This raises a deeper question: Is Australia prepared to detect and neutralize such threats? Myroshnychenko’s answer is clear: not yet. But what this really suggests is that Australia needs to rethink its defense strategy entirely. It’s not just about big-ticket items like nuclear subs; it’s about building resilience against unconventional threats.

The Broader Implications: Deterrence and Global Lessons

Here’s where the conversation takes a global turn. Myroshnychenko argues that Russia’s failure in Ukraine is the best deterrence Australia can build in the Indo-Pacific. In my opinion, this is a powerful point. If Russia can get away with its invasion, it sets a dangerous precedent for other nuclear-armed powers. But what’s even more interesting is his suggestion to use frozen Russian assets as a deterrent. If aggressors see that their assets will be seized, the cost of invasion becomes far too high.

This brings me to Australia’s $120 billion defense investment. While it’s a significant commitment, I can’t help but wonder if it’s enough. The Indo-Pacific is a region where the rules of warfare are being rewritten, and Australia needs to adapt faster than ever.

Conclusion: The Winter Is Here

If there’s one takeaway from all this, it’s that Australia’s winter has already begun. The warnings from defense chiefs, the lessons from Ukraine, and the evolving threats in the Indo-Pacific all point to one thing: the need for urgent, transformative action. Personally, I think Australia’s defense strategy needs to be less about traditional deterrence and more about agility, innovation, and resilience.

As Myroshnychenko puts it, “Whatever future warfare is going to look like, it’s going to be based on the experience in Ukraine.” Australia would do well to heed that warning. Because if winter is coming, it’s not just about surviving the cold—it’s about ensuring you’re not left out in the storm.
