Melanesia Cities Overview
The urban centers of Melanesia are relatively modest in size compared to other world regions, with Port Moresby, the capital of Papua New Guinea, standing as the region’s largest city with 283.7K residents. This reflects the region’s predominantly rural population distribution and the challenges of urban development in tropical Pacific island nations.
Each Melanesian nation is anchored by its capital city. Noumea in New Caledonia has 93.1K residents, while Suva in Fiji maintains 77.4K inhabitants. Honiara in the Solomon Islands has 56.3K residents, and Port-Vila in Vanuatu hosts 35.9K people.
Papua New Guinea, the largest country in the region, features several secondary urban centers, including Lae (76.3K), Arawa (40.3K), and Mount Hagen (33.6K). Similarly, Fiji has developed regional centers such as Lautoka (52.5K) and Nadi (42.3K).
