China intensifies maritime presence in South China Sea

China is intensifying its maritime presence and coercive reach in the South China Sea, posing a strategic threat to Australia. Despite global distractions, China has expanded its regional dominance through large-scale island-building at Antelope Reef, increased coast guard and maritime militia operations, and asserting jurisdiction outside its territorial seas.

The development of militarized artificial islands in the Spratlys allows China to project power further south, eroding the traditional security advantage provided by Australia's geographic distance. Recent advancements in long-range missile technology, including submarine-launched capabilities, further complicate the regional security landscape.
