A member of parliament in Papua New Guinea says a permanent processing facility for asylum seekers on Manus Island could take up to two years to build.
Manus Island MP Ronnie Knight says a more realistic option would be to extend the temporary facility, which he says could be done in a couple of days.
Mr Knight also says he doubts Australia's plan for those that get refugee status to be eventually settled in PNG will work.
He says obtaining citizenship in PNG is probably more stringent than in Australia.
Mr Knight says there are certain conditions the asylum seekers will not be able to meet.
He says instead they might be transferred to third countries in the region that maybe owe PNG some favours.
