Several hundred people rallied outside the department of immigration in Sydney on April 29.
They were part of nation-wide #BringThemHere actions, demanding the federal Coalition government bring the 850 asylum seekers and refugees currently in Manus Island Detention Centre to Australia.
Earlier in the week, the PNG Supreme Court had ruled that the detention centre was in breach of its constitution.
Aboriginal activist and Socialist Alliance Senate candidate Ken Canning said: "The way this government is treating these people, a lot of them will die — and that is murder."
The rally then marched to Deputy Leader of the Opposition Tanya Plibersek's office. While in government, the Labor Party opened the Manus Island Detention Centre, and continues to support the policy of offshore detention.
