Mr Dutton added that the Green's proposal is not viable because people smugglers would exploit the opportunity and that would result in an uptick of boat arrivals.
"We know, as the UN has told us, that there are some 58 million people who are displaced and would seek to come to a country like Australia, so the thought that you can somehow turn the tap on and off and that the people smugglers would be happy with the profit out of 50,000 but not out of 60 or 600,000 is complete nonsense...they would be here in the hundreds of thousands."
Mr Dutton also took aim at Opposition Leader Bill Shorten, saying under a Labor government terrorists would enter the country in the guise of asylum seekers.
"He doesn't have the metal to stand up to his own backbench let alone people smugglers and terrorists that would seek to do us harm and cross our borders," he said.
Peta Credlin, Sky News commentator and former chief of staff to the previous Prime MInister Tony Abbott, said it was important the Australian public was on board with government's immigration policy to avoid a 'feral outbreak' like Pauline Hanson's One Nation.
'You want Australians to support the level of intake because if you don't you get a feral outbreak like Hanson and you must not have that happen again,' she said.
