The United Liberation Movement for West Papua (ULMWP) has declared it will now base itself in the region after years of partial exile.
At a conference in Port Vila late last month - coinciding with the Melanesian Spearhead Group Leaders' Summit - UK-based Benny Wenda stood down as president.
Menase Tabuni is now president.
More than 50 representatives from West Papua and all over the world attended the summit in Vanuatu. It was only the second summit since ULMWP was formed in 2014.
The movement has an office in Vanuatu, a representative to the EU and some senior officials based in West Papua.
Tabuni will now lead the ULMWP from within West Papua, thereby, it said, maintaining its presence and solidarity with the Papuan people on the ground.
"I am honoured to be appointed as the new ULMWP President and I will do everything I can to continue our legitimate struggle for independence, Tabuni told Jubi TV.
"We must do this from within West Papua as well as campaigning in the international community.
"I will remain in Papua with the people while continuing to fight for human rights and my own determination."
Octovianus Mote is the new Vice President, Markus Haluk its Secretary, Benny Wenda for Foreign Affairs, Buchtar Tabuni is Chair of the Legislative Council and Apollos Sroyer as Chair of the Judicial Council.
The ULMWP is the umbrella organisation representing the main pro-independence organisations in West Papua, including the West Papua National Coalition for Liberation (WPNCL), the Federal Republic of West Papua (NFRPB) and the West Papua National Parliament (PNWP).
"ULMWP also wants to clarify that there is no 'Interim Government' and ULMWP is a representative body for all Papuans," Tabuni said.
Markus Haluk said the movement welcomed the decision of the MSG leaders to encourage Indonesia to allow the visit of the UN Human Rights Commissioner to West Papua, together with the Pacific Delegation.
The ULMWP, he said, continues to demand access for international media to be able to visit West Papua and report freely.
"Indonesia cannot call itself a democratic country if Indonesia continues to hide its largest province from the world," Tabuni said.
ULMWP also expressed its "deepest gratitude" to the Vanuatu government for hosting the MSG Summit and the ULMWP group, and also to the people of Vanuatu for their continued support.
At the MSG meeting in Port Vila, the leaders of five Melanesian countries and territories avoided a definitive update on the status of the ULMWP's application for full membership.
