Home Affairs Minister Peter Dutton has argued refugees brought to Australia for medical treatment would soon become citizens, against what he believes are the wishes of the community.
This latest warning follows his sensational claims that refugees medically evacuated from Manus Island and Nauru would take up hospital beds and public housing usually reserved for Australians.
The federal government has declared only asylum seekers with serious medical emergencies will continue coming to the Australian mainland for treatment.
All others, including women, will be put in detention on Christmas Island.
Mr Dutton has told radio station 2-G-B, the Medivac bill comes at a great cost.
