Bougainville raises K46.74 million a year of its own money. Running an independent state would cost K1.3 billion a year.
That K1.3 billion comes from the ABG's own accounting. NBC Bougainville and the Post Courier both reported the figure on 23 June, drawing on the cost-of-services report Treasury and Finance Minister Albert Punghau launched in Buka, titled "From Here To There" and commissioned with the National Economic and Fiscal Commission. Exepreneur has not independently verified it against the report.
Punghau described what governing Bougainville actually costs as an iceberg, PNG Haus B**g reported, with much of the expense sitting hidden inside national agency allocations in Waigani. "A sovereign people must be served by a government that can sustain itself," he said, Asia Pacific Report carried.
The ABG's 2026 budget is K844.09 million, of which K520.36 million arrives as National Government grants, per figures Punghau tabled and PNG Business News reported. Internal revenue funds 5.5 per cent of it.
Statehood costs more than that budget again. Closing the difference means raising 28 times what Bougainville raises today.
An independent estimate lands higher. Researchers at Harvard Kennedy School's Growth Lab put the annual cost of a fully sovereign Bougainville at the equivalent of K1.5 billion to K2.1 billion, in a March 2026 dispatch by Niklas Piringer and Anna Christina Thorsheim advised by Professor Ricardo Hausmann, covering courts, police, health, education, foreign affairs and infrastructure. Bougainville's own figure sits below their range.
The Bougainville Independence Leaders Consultation Forum endorsed 1 September 2030 as the declaration date on 28 July, Islands Business reported.
