In this episode, Tania Nugent is on Papua New Guinea's Indonesian border, in the village of Wutung in Sandaun Province, where she looks at the challenges and opportunities for the people whose customary land was split when the Dutch colonised the west of the island in 1881, leaving them living on the edge of two countries. Clement Paligaru is amid the bustle of Honiara's market in the Solomon Islands capital where he talks to women who make the elaborate strands used as shell money - a traditional currency that continues to be used today for trade, compensation and bride price.
