Why it matters
A formal China–Indonesia security alignment targeting 'external forces' directly threatens Australia's Pillar 7 (Alliance) and Pillar 8 (Northern Arc) by eroding the Western coalition's influence in Southeast Asia and raising the prospect of Chinese military accommodation in the Indonesian archipelago. Indonesia's pivot away from the Quad/AUKUS consensus materially increases the risk of Chinese power projection into Australia's Northern Arc and constrains allied freedom of manoeuvre in the Indo-Pacific.
