The National Anthem of Papua New Guinea (PNG) was composed by Thomas Shacklady, a decorated Superintendent in the Marines from the United Kingdom who served during World War II. As the bandmaster of the Royal Papua New Guinea Constabulary Band from 1964 to 1982, Shacklady not only led the band to international acclaim with tours across Australia, New Zealand, the United States, Southeast Asia, other Pacific Islands, and a notable performance at the 1970 Edinburgh Tattoo in Scotland, but he also played a significant role in PNG’s cultural history.

In early 1975, Shacklady won a competition to create PNG’s National Anthem, crafting both the lyrics and music for “O Arise All You Sons of This Land.” This piece was adopted just a week before Independence Day in 1975, quickly symbolising national unity and pride. The anthem is recognised under Section 3 of the PNG Constitution as a national symbol, alongside the Flag, Emblem, Seal, and Motto, and it continues to inspire patriotism and unity across the country.

The anthem is intended to be played or sung at all official and other appropriate occasions. However, any disrespectful reprinting, reproducing, playing, or singing of the National Anthem, which could be considered insulting or derogatory to the Independent State of PNG, is an offence punishable by a fine not exceeding K1000.00.

Shacklady was honoured as a Member of the British Empire (MBE) for his invaluable contributions in 1977. His enduring legacy continues to echo in the hearts of Papua New Guineans every time the anthem plays, celebrating the freedom and unity of their country.
