AUKUS Debate: Can Australia Defend Sea Trade Lanes? Greens Senator Shoebridge Weighs In (2026)

Australia's Strategic Conundrum: AUKUS and the South China Sea

The AUKUS agreement, a strategic alliance between Australia, the United Kingdom, and the United States, has sparked a fascinating debate about Australia's role in the Indo-Pacific region and its relationship with China. The recent comments by Greens defence spokesman David Shoebridge shed light on a crucial aspect of this discussion: Australia's ability to project power and protect its interests in the South China Sea.

Shoebridge's argument that Australia is too small to defend sea trade lanes, especially the Strait of Malacca, is a thought-provoking one. It highlights a fundamental question: Should Australia aspire to be a global policeman, or is it more prudent to adopt a nuanced approach to regional security?

Personally, I find the idea of Australia taking on a global policing role in distant waters somewhat far-fetched. Australia's military capabilities, while significant, are not on par with those of superpowers like the US or China. Attempting to secure sea trade lanes thousands of kilometers away seems like a stretch, especially when considering the economic and logistical challenges involved.

What many fail to grasp is that the South China Sea is a geopolitical hotspot, with multiple nations vying for influence. The Strait of Malacca, a vital chokepoint for global trade, is a prime example. Any disruption here could have far-reaching consequences, affecting not just Australia but the entire region's economic stability.

The AUKUS agreement, with its focus on nuclear-powered submarines, is primarily about power projection. The acquisition of these submarines is seen as a way to counter China's growing naval might. However, Shoebridge's point about the 'ridiculousness' of this approach is worth considering. Australia's defence strategy should be more than just a reaction to China's rise; it should be a well-rounded, independent policy.

In my opinion, Australia's defence planning should prioritize diplomacy and regional cooperation. As Shoebridge suggests, Australia should learn from its Asian neighbours, who are navigating complex relationships with China. A balanced approach is key. Australia can maintain strong ties with the US while also fostering better relations with China and other regional powers.

The debate over AUKUS also reveals a deeper issue—the evolving nature of alliances. With the US-China rivalry intensifying, countries like Australia are caught in the middle. The decision to align with one power over the other is not just about military might but also about economic and political interests.

Interestingly, the potential delays in the AUKUS deal due to US domestic issues further complicate matters. This uncertainty underscores the need for Australia to explore alternative defence strategies, as Shoebridge proposes. A diverse force structure, including crewed and uncrewed submarines, could provide more flexibility and resilience.

As an analyst, I believe Australia's defence policy should be a careful balance between its alliance commitments and its national interests. While AUKUS offers technological advancements, it should not be the sole pillar of Australia's defence strategy. A more comprehensive approach, considering regional dynamics and diplomatic solutions, is essential for Australia's long-term security.
