Morrison won't amend 'medevac' legislation

Prime Minister Scott Morrison says the government won't seek to amend the so-called "medevac" bill when parliament resumes next month.

Labor, the Greens and crossbenchers teamed up in the last sitting to secure the passage of laws which make it easier for asylum seekers on Manus Island and Nauru to get medical treatment.

The government said the passage of the bill forced it to reopen the Christmas Island detention facility at a cost of more than $1 billion.

Labor has questioned why the facility needs to be reopened, given it has very limited medical facilities, and asked why amendments were not brought to parliament if the government had such major concerns.

Mr Morrison told reporters in Sydney on Monday there was no form of the medevac bill which the government would support.

"The only thing I would seek to do is repeal it in its entirety and the Australian people will have the opportunity to talk about that at the next election," he said.
