Home Affairs Minister Peter Dutton has ruled out signing a global pact on migration, insisting he won't allow the United Nations to undermine Australia's borders.
More than 190 countries have agreed to the pact, which seeks to promote safe and orderly migration and reduce human trafficking, but Australia will not be joining them.
When asked if Australia would sign the document, Mr Dutton replied: "No."
"We're not going to sign a document that surrenders our sovereignty," Mr Dutton told 2GB radio on Thursday.
"We're serious about keeping our borders secure. We're not going to allow the UN or anybody else to disrupt the hard work that's taken place."
Mr Dutton suggested some European countries were losing their identities after being flooded by millions of undocumented immigrants.
"In generations to come that will have a huge impact on those societies," the minister said, adding the threat to Australia posed by people smugglers had not gone away.
"We're not going to give up those hard-fought gains."
