The document summarizes reconstruction and rehabilitation efforts in Papua New Guinea following World War II and issues that arose. Under Australian administration, infrastructure like roads, railways, and air transport were developed. Aid to education and health increased to prepare Papua New Guinea for self-determination. Local councils were established to encourage Western-style democracy. By the 1950s, airfields and coastal shipping were the primary means of transport, while some plantation railways also operated. Later, the Bougainville Civil War erupted over a copper mine, and nuclear testing negatively impacted parts of the Pacific.
