Since its inception the OPM has attempted diplomatic dialogue, conducted Morning Star flag-raising ceremonies, and undertaken militant actions as part of the Papua conflict. Supporters routinely display the Morning Star flag and other symbols of Papuan unity, such as the national anthem "Hai Tanahku Papua" and a national coat of arms, which had been adopted in the period 1961 until Indonesian administration began in May 1963 under the New York Agreement. The militant movement is considered as a separatist organisation in Indonesia, and agitating for independence for the provinces has incurred charges of treason.
