Papua New Guinea–Bougainville: Independence negotiations almost certain to continue despite parliamentary vote

On 5 August, the Joint Supervisory Body (JSB), co-chaired by PM Marape and President Ishmael Toroama, endorsed the Post-Consultation Report and Melanesian Agreement, making way for the 2019 referendum result to be tabled and finalised in PNG's National Parliament on 27 August. The referendum recorded 97.7% support for independence, but the result is non-binding and requires parliamentary ratification under Section 342 of the Constitution to trigger independence. President Toroama reiterated Bougainville's position that independence is non-negotiable while calling out "bureaucratic manoeuvring" with the setting of a three-quarters threshold to pass. The Autonomous Bougainville Government plans to declare independence in 2030, while PM Marape has linked any transition to financial self-sufficiency, peace and stability, and an end to armed violence and factionalism.

Assessment: Regardless of the National Parliament's vote, the JSB and Melanesian Framework Agreement will almost certainly remain the mechanisms for negotiations on Bougainville's independence and to reduce the risk of conflict. PNG and Bougainville remain divided over both Bougainville's political future and the timeline for independence. These differences are likely to prolong negotiations and create political tensions.
