Since its inception in 1983, the Agreement has undergone three reviews, the first review was undertaken in 1993, the second one in 2003 and the third was undertaken in 2013, after which Indonesia has formally ratified the 2013 revised Agreement whilst PNG is yet to do so.
This agreement is now up for review but before that takes place, PNG must ratify the agreement and thereafter have it subjected for review by both the two contracting parties.
