Indonesia has lost a significant asset from in its Pacific diplomacy efforts with the recent passing of the West Papuan, Franzalbert Joku.
The prominent Sentani landowner was the international spokesman for the Papua Presidium Council which galvanised momentum in the independence struggle at the turn of the century.
But in his last decade, Mr Joku strongly advocated autonomy for Papua within Indonesia rather than independence. He often represented Indonesia at regional meetings of the Melanesian Spearhead Group and the Pacific Islands Forum.
Mr Joku, who died at the age of 66 late last month in Jayapura, had fled from Indonesian rule in his homeland as a youth with his family in the early 1970s. For around three decades he lived in various parts of Papua New Guinea where Mr Joku worked as a journalist and a PNG government advisor who developed extensive links in the Pacific.
An expert in Indonesian history and politics, Richard Chauvel of the University of Melbourne, says Mr Joku's career in PNG was significant.
"His great utility both in the early 2000s (for the Papua Presidium) and post 2007/8 for the Indonesian government has been his intimate knowledge of Papua New Guinea politics, through his role as a journalist and then as a political advisor or spokesman for (former PNG PM) Julius Chan and other senior PNG politicians," Dr Chauvel said.
"I think it's that knowledge of local PNG politics, and through networks into the Pacific, that made him such a formidable figure, both initially for the Presidium, in the lobbying of the Melanesian Spearhead Group and the Pacific Islands Forum, and then subsequently for doing much the same thing, utilising the same skills and knowledge for the Indonesian government," he explained.
As an effective envoy for Jakarta, Mr Joku had a forthright approach to his diplomacy, as evidenced last year by his instrumental role in pressing the Solomon Islands government to mollify its support for West Papuan self-determination aspirations:
Occupying both extremes of the Papuan political spectrum over time made Franzalbert Joku a polarising figure in the eyes of West Papuans.
"The way he executed those positions was remarkably the same - with great commitment, very articulate, he was obviously a bright guy... you could never accuse him of being nuanced," Dr Chauvel said.
Dr Chauvel first met Franzalbert Joku when he was lobbying for the Presidium, the organisation which energised the independence struggle as democatic space opened up briefly in post-Suharto Indonesia around the time of the Papua People's Congress in 2000 in Jayapura.
"He was just as vigorous and forthright in his advocacy of that position as he later became from 2007/8 onwards when he'd clearly joined the other side," he said.
Indonesia's Foreign Affairs Ministry has a number of officials who have led delegations to MSG and Pacific Forum meetings over the past decade.
"They have acquired some of that background knowledge, but I don't think that they can speak to their counterparts in Vanuatu, Fiji, Solomon Islands and PNG from the same position as Franzalbert could, as a Pacific Islander," Dr Chauvel said.
