Impact is the average of the four parts, rounded, plus one point when Canada is directly hit on two or more channels, up to 10.
Two separate scales from 1 to 10. Strature never multiplies or merges them.
What changed
Dated, newest first
- ABG leaders endorsed self-government in 2027 and independence in 2030; responsibilities assumed on 1 Sep 2027; no September-October news of a vote date [3]
Why it matters
Bougainville voted 97.7% for independence in 2019, but Papua New Guinea's Parliament only tabled the result on 27 Aug 2026 and set no date for the vote. The two sides dispute the 89-vote threshold. Bougainville plans self-government from 1 Sep 2027, and PNG holds a national election in 2027.
Why Likelihood 5 Pushes: no date set, the October target passed unreported; the 89-vote dispute; the 2027 election. Brakes: Marape's stated plan; Bougainville's 2027 deadline pressure. One source each side: an open contest.
Why Impact 5 Threshold case no vote by 1 Nov 2027.
The other facts on file (3)
- Referendum result (97.7% for independence) tabled 27 Aug 2026; Parliament adjourned; Marape said the two governments would meet in October to set the vote's date; decision at least months away [1] (28 Aug 2026)
- Sessional order requires a three-quarter absolute majority, 89 votes; PNG cites section 342; Bougainville's Speaker says the sides worked on a simple majority [2] (12 Jun 2026)
- Marape committed to a safe, free, fair and credible 2027 national election; no polling date given [4] (29 May 2026)

Three scenarios and their signposts
- S1
Vote held
A date is set and Parliament votes before the election.
- S2
Election pause
Parliament rises for the 2027 election without a vote.
- S3
Unilateral step
Bougainville acts alone on 1 Sep 2027.
| Path | Signpost |
|---|---|
| S1 | A date announced after the two governments meet |
| S2 | Writs issued with no vote taken |
| S3 | The ABG's self-government declaration |
No probability is given for the three paths.

The other side
A settled path, by vote or agreed self-government, could reopen talks on Panguna and bring investment to Bougainville (Strature's view). The ABG is already running independence-readiness consultations [3].
