Status verified as of 14 September 2026. Political positions change; this explainer describes the documented position on that date.

The referendum result

In the referendum held from 23 November to 7 December 2019, 176,928 votes were cast for Independence and 3,043 for Greater Autonomy, with 1,096 informal ballots among 181,067 counted.[1][2] The Commission described the result as non-binding.[3]

What the agreements provide

The 2001 Peace Agreement makes the referendum outcome subject to ratification by the National Parliament, with final decision-making authority, after consultation between the two governments.[4] The governments began those consultations in January 2021 and endorsed a Joint Consultation Report and the Melanesian Framework in early August 2026.[5][6]

Implementation so far

Parliament has set a three-quarters absolute majority, at least 89 of 118 MPs, for ratification, a threshold disputed by Bougainville’s leaders.[7][8][9] The result was tabled on 27 August 2026 and Parliament adjourned without a vote.[10] Prime Minister Marape said the governments would meet in October to set the date for the vote.[11]

Separately, the Joint Supervisory Body has agreed further transfers of revenue and constitutional powers under the existing autonomy arrangements.[12]

Is Bougainville an independent state?

No. As of late August 2026 Bougainville remained an autonomous region of Papua New Guinea.[13] The ABG proposes self-government from 1 September 2027 and independence in 2030, while the PNG minister responsible said an affirmative parliamentary vote would lead to a transitional phase rather than immediate independence.[14][15]
