Smuggled in under cover of darkness, we just recorded explosive new footage from inside the Manus detention centre.

Six hundred men were sick, starving and thirsty. Just to sleep, they dragged their mattresses out of crammed steel sheds to escape the searing heat. They were living without power, water or medicine. And for all that, they feared even more where they could be taken next.

The GetUp Human Rights Directors, Matthew Phillips and Shen Narayanasamy, are human rights experts with refugee crisis experience in places like South Sudan — what they witnessed was the worst they'd ever seen.

Our Government's fences and walls, their gag rules and media blackouts, were designed to hide these appalling conditions from the Australian people — to prevent the tide of public outrage that could sweep down this abusive regime.

This heart-wrenching footage has the power to shame our parliament into action — The Daily Telegraph and other News Corp tabloids ran these images as front page stories calling the conditions horrific.

That's why the most important thing to do now is to see what we have seen — and share it with everyone you know.

Since this footage was released late last year, the men have been forcibly moved to new detention centres closer to Lorengau. They still face locals who are angry at the Australian and PNG governments for abandoning 600 men in their community, facilities that are incomplete and for many, their fifth year imprisoned on Manus Island.

Can you help shame our Parliament into action by sharing this explosive footage from inside the Manus Island detention camp?
