Hundreds of Manus Island detainees say they've run out of food and are relying on rainwater collected in wheelie bins to survive.
The refugees are defying orders to move to another facility, saying they'd rather starve than risk their safety outside the compound.
"It's still torture for us here," says one detainee, in a desperate message to the world.
"All of them need freedom. We're not criminals."
"We are powerless," says asylum seeker Abdul Aziz Adam. "We don't have arms; we don't have weapons. We don't have anything."
Detainees have been told to relocate, but no one wants to, saying the alternative accommodation is unfinished, less secure and that they'll face violence from locals.
"We wish to stay and we wish to die in this place," says Mr Adam. "We do not want to leave."
Power has been cut. Showers and toilets are no longer functioning. Rainwater collected in bins is all they have left.
"This water - we just put a little bit of sugar and salt and we drink this water," says Mr Adam. "We can stay maybe for a month without food. We don't have any food."
"I haven't eaten since yesterday and drinking water is severely limited," says detainee and civil engineer Farhard Rahmati.
"To be honest, I'm just trying to survive - that's it."
Last year, Australia rejected New Zealand's offer to take 150 Manus refugees, claiming the offer could incentivise people smugglers.
Amnesty International wants New Zealand to negotiate directly with local authorities.
"It would be very helpful if countries - New Zealand and others - extended their offers to the Papua New Guinean government," says Amnesty International Pacific researcher Kate Schuetze.
"Politicians in New Zealand, they know about this situation, but no one says anything," says Mr Rahmati.
Any talks or deals between Papua New Guinea and politicians look unlikely.
"It remains our intention to deal directly with the Australian government," says Immigration Minister Iain Lee-Galloway.
The offer to take 150 refugees still stands.
