It is the southernmost terminus of the Kiunga-Tabubil Highway. Local industry rests on a cornerstone of freight and haulage, particularly from the Ok Tedi Mine and provisioning for the much larger town of Tabubil. Natural rubber has been an emerging industry more recently, with a processing/manufacturing plant being built in town.
