Australian Prime Minister Malcolm Turnbull announced on Monday that his country will team up with New Zealand in a bid to negotiate new trade and immigration deals after Britain's exit from the European Union (EU).
He also ordered review from Treasury officials and diplomats over the implications of the exit, ABC News reported.
Turnbull said in Adelaide that he had been in contact with his New Zealand counterpart John Key, warning the implications of Friday's historic vote were "considerable".
"We have many, many common interests in terms of dealing with that, both from a trade point of view, from a movement of persons point of view," he said.
"There are some big issues in terms of the access of Australians and New Zealanders to Europe and indeed to the UK."
The PM said he wanted to establish a "collaborative, cooperative framework" with New Zealand if he was re-elected in the federal elections scheduled for July 2.
