Australia must not be distracted as China ramps up its activity in the South China Sea, even as the world’s attention is pulled toward other global hotspots. From the Middle East to Venezuela, 2026 has offered no shortage of crises fighting for headlines. However, while eyes are elsewhere, China continues to tighten its grip on waters that sit right on Australia’s doorstep.
These waters are not a distant concern. Roughly two-thirds of Australia’s trade passes through the South China Sea. Furthermore, as military technology advances, this same stretch of ocean is becoming a launchpad for power projection toward Australia itself. That is why analysts are urging policymakers to keep their focus firmly on the region, rather than letting it slip down the priority list.
Why the South China Sea Matters to Australia?
China’s claim over roughly 90 percent of the South China Sea has stood for decades. In fact, a 2016 international tribunal ruled that Beijing’s “historic rights” claim had no legal standing under the UN Convention on the Law of the Sea. Nevertheless, a decade later, the situation on the water tells a different story, one where Chinese military and government control keeps expanding regardless of the ruling.
Consequently, Australia faces a strategic dilemma. Global crises will always compete for attention. Yet, if policymakers and the public overlook what’s happening in nearby waters, the country risks being unprepared for a much closer threat.
Three Warning Signs Australia Cannot Ignore
Analysts point to three specific developments driving fresh concern.
Island-Building Returns to Antelope Reef
China has restarted large-scale island construction at Antelope Reef. Historically, this kind of building work has been followed by militarisation, meaning today’s construction project could become tomorrow’s military outpost.
Coast Guard and Militia Numbers Are Surging
China’s coast guard and maritime militia, civilian-looking fishing boats used to reinforce territorial claims, have dramatically stepped up operations. Near Scarborough Shoal alone, located only 222 km from the Philippine island of Luzon, over 900 Chinese coast guard ship-days were logged by mid-2026. That figure already matches the entire 2025 total, putting this year on pace to double it. Meanwhile, the maritime militia hit a record daily average of over 240 vessels in 2025.
China Tests New Waters Near Taiwan
For the first time, Chinese coast guard vessels moved east of Taiwan, questioning commercial ships about their origin and destination while asserting jurisdiction well beyond China’s own territorial waters. As a result, this move has raised fresh concerns about freedom of navigation, and some analysts believe it could be an early test of a future blockade around Taiwan.
The Scarborough Shoal Flashpoint: A Collision Course
Scarborough Shoal has become the epicentre of these rising tensions. Around the July ASEAN foreign ministers’ meetings in Manila, several dangerous incidents unfolded there and near Second Thomas Shoal. Chinese coast guard crews reportedly used water cannons, and in one case, a Philippine sailor was struck with a wooden baton.
This pattern isn’t new, either. Collisions between Chinese and Philippine vessels have occurred repeatedly over the past two years, and a notable 2025 incident even saw a Chinese navy ship collide with its own coast guard vessel while chasing a Philippine patrol boat. ABC’s Foreign Correspondent: Collision Course explores this exact flashpoint, with the Philippines’ defence minister warning that the rest of the world should be worried if it wants to protect freedom of movement through one of the planet’s busiest shipping lanes.
Distance No Longer Guarantees Safety
Australians have often taken comfort in geographic distance from Asia’s flashpoints. Historically, that comfort was justified. However, the rise of long-range missile technology has eroded much of that safety margin. Modern missiles can now be launched from land, ships, aircraft, and, as China’s recent submarine-launched ballistic missile test demonstrated, from submarines too.
Sustained military operations against Australia would still be logistically difficult for China. Even so, its heavily fortified artificial islands in the Spratly chain extend Beijing’s reach much further south than many realise. So, while a hypothetical future Chinese base in the Pacific grabs headlines, the bases China already operates in the South China Sea deserve just as much scrutiny.
What Australia Has Done, and Where It Falls Short?
To its credit, Canberra hasn’t stayed silent. Foreign Minister Penny Wong used the ASEAN meetings to publicly call out China’s destabilising conduct. Australia has also boosted support for the Philippine Coast Guard this year, supplying uncrewed aerial and underwater vehicles, alongside a regular naval presence in the region.
That said, Australia’s small naval fleet limits what these gestures can realistically achieve. A single deployed ship can signal presence, but it can’t sustain a meaningful response over time. More importantly, the government hasn’t clearly explained to everyday Australians why these distant disputes actually matter for their own security.
Why This Story Deserves More Public Attention?
Ultimately, the South China Sea offers one of the clearest, most tangible examples of how quickly the regional security picture has shifted. Global conflicts elsewhere will always demand attention and resources. Still, Australia cannot afford to look away from the waters immediately to its north.
As debates continue over nuclear-powered submarines, defence budgets, and national resilience, the public deserves a plain-language explanation of what’s changing nearby, and why it matters. In short, Australia must not be distracted as China ramps up pressure in the South China Sea, because the stakes are too close to home to ignore.
FAQs on Australia and the South China Sea
Why is the South China Sea important to Australia? Around two-thirds of Australia’s trade passes through it, and it’s increasingly used as a platform for regional power projection.
What is Antelope Reef? A reef where China has resumed large-scale island construction, raising fears of future militarisation.
What happened at Scarborough Shoal? A series of aggressive encounters between Chinese and Philippine vessels, including water cannon use and physical confrontations, escalating tensions in the area.
Has Australia responded to China’s actions? Yes, through diplomatic statements, support for the Philippine Coast Guard, and naval deployments, though critics say the response and public messaging remain limited.
