It would be in Australia's best interest for the UK to remain in the European Union, Foreign Minister Julie Bishop believes.
Britons go to the polls on Thursday to vote for a "Brexit" or a "Bremain".
Ms Bishop expects considerable economic volatility if the UK votes to leave the bloc, but acknowledges it is a decision for the British people.
Australia and Britain had a deep economic, strategic and historic relationship with important intelligence and security ties, she said.
"To have a like-minded partner within the European Union would be in Australia's interest," Ms Bishop told a Lowy Institute lunch on Monday.
The EU was a top trading bloc for Australia, so increased instability within the organisation could have some fallout here, she said.
