Papua New Guinea (PNG) is arguably the most diverse indigenous population in the world, with a reported 840 indigenous living languages. The country was first colonised in 1884 by Germany and this was followed by Australia until it gained independence in 1975. Australia continues to have significant interests in PNG, with extensive extractive industry investments, and provides considerable donor funds to the country which heavily influences policy, including in education. In my PNG search I found this team of entrepreneurs looking for ways to use technology to address economic and social issues in the country.
