As many as 72,000 Australians will be at British ballot boxes on Thursday June 23 for the European Union referendum. But what does it mean for Australia?
The "Leave" campaign has been aggressively targeting Commonwealth voters.

But how would Australia benefit from Britain leaving the European Union?
The head of the anti-EU UKIP Party, Nigel Farage, says it would free up Britain's trade with Australia.
"Well, we'll be able to be friends with you again, to have trade deals with you again," he said.
"You know, we turned our backs on you appallingly just over 40 years ago.
"Freed from the European Union, we can make our own trade deal with whomsoever we choose."
UKIP is pressuring British Prime Minister David Cameron to keep his promise and limit annual migration to the tens of thousands.
A total of 373,000 migrants arrived in Britain last year.
Almost half of them came freely, from one of the 27 other EU nations, while the others came from elsewhere and had to qualify.
Even a complete stop to EU migration would fall well short of the government's target.
Despite talk of restoring old friendships, it raises an obvious question: Would it be easier for Australians to live and work in Britain?

Mr Farage does not exactly answer that question.
"It will be fairer, and that's the point," he said.
"We can have a flexible work-permit scheme just like we used to. We used to have lots of young Australians come to this country for a short period of time, and that was quite helpful."
But Australia's former High Commissioner to Britain and ambassador to Italy, Mike Rann, takes a very different view.
"This would be Britain's biggest own goal since the Second World War," he said.
Mr Rann said Australia's economic priority was an EU trade deal.
"If Australians vote to support Brexit, it would be like turkeys asking for an early Christmas, because it is absolutely in Australia's interest to have Britain within the EU so that we can then have access to a free-trade agreement with 500 million people, not with 60 million," he said.
"Our champion inside the EU has been Britain. If they pull out, then we've lost our champion, and we've got problems with some countries that actually are resisting supporting Australia going in."
