Port Moresby History

Since its early days, Port Moresby has always been a spot designated for trade. The Motuan people would trade sago and pots for canoe logs and food.

John Moresby was the first European to arrive at Port Moresby. In the late 1800s, he claimed the land for the British. Later, Queensland tried to annex the southeastern corner of New Guinea Island, but this was not approved by the British. A protectorate over Papua as British New Guinea was established a few years later.

In the early 1900s, the Papua Act transferred Papua and Port Moresby to Australians. It was during this time that the city began to grow. Port facilities were improved, grocery stores and butcher shops were opened, and electricity was brought to the city.

During the 1940s, the city also became an important area for Allied bases during World War II. It was also during the 1940s that the Territory of Papua and New Guinea was combined and Port Moresby was named as capital.

It was during the 1970s that Papua New Guinea gained its independence. Government buildings, businesses, and cultural buildings were built as a result. Once the city gained its independence, the population grew significantly, climbing from 120,000 in 1980 to almost 200,000 during the 1990s.
