An Australian academic says both the Papua New Guinea and Bougainville governments should sit down and sort out concerns over funding.
For several years the autonomous Bougainville government has complained that the national government has failed to fulfil its financial obligations under the Bougainville Peace Agreement.
There are severe shortages across the Bougainville public sector and the ABG says this is hampering its preparations for a referendum on independence in 2019.
Bougainville president John Momis says both parties could seek a court arbitrated resolution, but Professor Ted Wolfers, who has been an advisor on Bougainville issues and helped draw up the Peace Agreement, told Don Wiseman, they should just sit down and start talking it through.
He says there appear to be two issues.
