The group, Pacific Freedom Forum, has condemned the stabbing of a journalist in Papua and are joining ongoing calls for Indonesian authorities to investigate a series of attacks against news media.
Banjir, who is a reporter for the Jakarta Globe, was attacked in Jayapura last week by two men.
One of Banjir's recent stories had been about a woman detainee forced to give oral sex to three officers and the pack rape of an underage girl by other officers, who locked the 15-year old in a room for a week.
The Freedom Forum's chair, Susuve Laumaea, has spoken out against a climate of impunity.
He says the attack is the sixth on news media in Papua this year.
