Peter Dutton’s cuts to support payments for people seeking asylum are cruel, punitive and unfair, Greens Immigration Spokesperson Nick McKim says.

“This is a deeply unfair decision which could force people into poverty, homelessness and exploitative jobs,” Senator McKim said.

“It is a continuation of Dutton’s determination to punish migrants and undermine multiculturalism.”

“Many people affected by these cuts are studying, and all of them are trying to rebuild their lives.”

Immigration Minister Peter Dutton must immediately intervene so a pregnant woman on Nauru suffering serious health problems can receive medical assistance, Greens Immigration spokesperson Nick McKim says.

"I have today written to Mr Dutton seeking his urgent intervention in this case," Senator McKim said.

"Medical specialists have demanded that she be immediately brought to Australia to receive the care she so desperately needs."

"It is really sad that we need to ask the Immigration Minister to show basic humanity to people who are in his care."
