Talks on Manus Is may take 'months'

Australian officials have held "constructive" talks with their Papua New Guinea counterparts about the future of the Manus Island immigration detention centre.

The centre's future was cast into doubt by a PNG Supreme Court ruling it was illegal, and Immigration Minister Peter Dutton said on Monday it could take months to resolve the matter.

"We will have what I think will be detailed and long-run discussions with PNG to help them in relation to this particular issue," he told reporters in Brisbane.
