Port Moresby hosts Britain's High Commission to Papua New Guinea where tribal diversity meets resource wealth and British engagement in Pacific island nation. The mission coordinates bilateral relationship built on Commonwealth membership since 1975 independence, historical Australian administration under British oversight, development aid supporting governance, and security cooperation. British tourists visit PNG minimally despite spectacular attractions with FCDO advising extreme caution due to violent crime epidemic making Port Moresby among world's most dangerous cities, though intrepid travelers seek Kokoda Track's WWII trekking pilgrimage, highland tribal festivals showcasing sing-sings and traditional dress, diving pristine coral reefs including wreck diving in Milne Bay, volcano climbing Mount Tavurvur, Sepik River cultural expeditions, and unique biodiversity. British expats maintain small presence in mining sector, development organizations, and diplomatic community operating under strict security protocols. British businesses engage in PNG's mining sector with British companies extracting gold and copper, oil and gas development, development consulting, and financial services despite challenging business environment with corruption and infrastructure limitations. The High Commission coordinates development aid supporting governance in nation struggling with service delivery to remote populations, monitors political instability and tribal violence affecting outlying provinces, and facilitates British interests in resource-rich but underdeveloped Pacific state. Staff operate under severe security constraints in high-crime capital requiring fortified compounds and restricted movement, support British nationals facing risks from violent crime including carjackings and armed robbery, and maintain presence in challenging environment. The mission represents British interests in strategically located Pacific nation where 800+ languages and extreme cultural diversity create governance challenges, resource revenues from mining fail to translate to widespread development, Australia's dominant influence limits British role, and PNG's position north of Australia makes bilateral engagement important for Pacific stability despite security environment constraining operations.
