The services sector in Papua New Guinea is small and almost entirely in the public sector . This sector employs an estimated 17.2 percent of the labor force , consisting mainly of government employees such as administrators, teachers, and health care workers. Approximately 66,000 tourist visas were issued in 1997, though under 10,000 of these are "real" tourists, with the others being people visiting relatives and other temporary visitors. Tourism generated US$72 million in 1997, but the high cost of travel to and within the country limits tourism development at present. Financial services are likewise a limited sector.
