On September 16, 1975, Papua New Guinea gained full independence from Australia, with Michael Somare becoming the country's first prime minister. Despite its separation from Australia, Papua New Guinea remains part of the Commonwealth.
Independence Day is usually celebrated with flag raising ceremonies, open air music, dances, markets, and fireworks. The national colours of gold, red and black feature prominently in the streets, shops, homes and clothes.
However, during this year of the pandemic, there will not be the usual crowds and social gatherings.
Prime Minister James Marape said that traditional public and big-scale celebrations associated with Independence Day have been cancelled.
The event will have "scaled-down symbolic" activities around the country, Marape said.
"We can still celebrate but not in the usual way," he said.
Marape said the usual funding for the celebrations to districts and provinces had been cancelled as the economy was struggling. "We are prioritising other areas," he said.
