The organisation called the Federal Republic of West Papua is urging the Pacific Islands Forum and the Melanesian Spearhead Group to address ongoing abuses in Indonesia's Papua region.
The imprisoned President of the Federal Republic, Forkorus Yaboisembut, and other members of his administration have been in jail since their election at the Third Papuan People's Congress in October 2011.
A spokesman for the administration, Jack Wanggai, says Mr Yaboisembut is expected to be released soon and is already implementing resolutions made by the administraion at the congress.
He says this includes pushing for international engagement over West Papua.
"Many conflict in here, many conflict made from Indonesian government like military or soldier. Every day. That is why South Pacific (Forum) or Melanesian Spearhead Group must make politic statement to help west Papua people."
