In the years leading up to independence, Papua New Guinea experienced a growing movement towards self-governance, driven by rising nationalist sentiments among the diverse ethnic groups. Following World War II, Australia administered the region as a territory under its authority, which fueled aspirations for autonomy among the local populations. The push for independence gained traction during the 1960s and 70s, spearheaded by various local leaders and emerging political parties. The establishment of the House of Assembly helped nurture political dialogue and awareness. The constitutional framework crafted advised on providing representation to the various cultural groups while ensuring a stable governance structure. On the day of independence, prestigious ceremonies were conducted at public venues, including the Parliament House, symbolizing the transition from colonial rule to self-determination, with the new flag raised and the national anthem sung.
