Australian police say the return of some of their officers to Papua New Guinea will lead to the setting up of a joint task force on transnational crime and terrorism.
The Australian police commissioner, Mick Keelty, says the task force will be in addition to other advisory and mentoring duties and could require extra police numbers.
The comment comes after PNG and Australia discussed new plans for about 30 Australian officers to return to PNG.
Under a previous deal, 150 Australian police were in PNG but they left after the PNG's Supreme Court ruled their legal immunities were invalid under the constitution.
PNG has refused Australian moves to change its constitution to exempt Australian police.
