Papua New Guinea country profile

Papua New Guinea occupies the eastern part of the world's second largest island and is prey to volcanic activity, earthquakes and tidal waves.

Linguistically, it is the world's most diverse country, with more than 800 languages.

Some 80% of the population live in rural areas. Many in the isolated mountainous interior live within a non-monetarised economy dependent on subsistence agriculture.

In 2019, the inhabitants of Bougainville voted to become independent from Papua New Guinea by 2027, but the central government has said it has the final say.

Head of state: Charles III, represented by a Governor-General

Prime minister: James Marape

Parliament elected James Marape prime minister in May 2019, after the resignation of his predecessor Peter O'Neill.

This followed Mr Marape's own resignation as finance minister in April due to differences over a high-value gas deal.

He was re-elected as prime minister following parliamentary elections in July 2022.

Radio is important in Papua New Guinea, which has scattered, isolated settlements and low levels of literacy.

The government operates a national network and provincial stations. The media operate in a relatively free environment, says Reporters Without Borders (RSF).

Television coverage is limited mainly to Port Moresby and the provincial capitals.
