Opposition Leader Bill Shorten has warned Australians against voting for a "weak" Malcolm Turnbull or a "divided" Liberal Party, as he attempts to capitalise on Britain's vote to leave the European Union.

The United Kingdom's decision to split from the EU has rocked the Australian election campaign, just a week from polling day.

Prime Minister Turnbull said the uncertainty caused by Brexit meant Australian voters should retain his "stable" Government.

But Mr Shorten said there were dangerous parallels between outgoing British leader David Cameron and Mr Turnbull.

"[Malcolm Turnbull] is a weak man beholden to the right wing of his party. The disunity that that represents in the Liberal Party is not a risk worth taking for the Australian people," Mr Shorten said.

"What we saw there was David Cameron hostage to the right wing of his political party, compromising his own beliefs, providing weak leadership. Sounds familiar, doesn't it?

"David Cameron didn't want the referendum about leaving Europe, but he was forced to do it by the right wing of his party."

Mr Turnbull did not bite back at the Opposition Leader's remarks, saying he was focused on Australia's economy.

"[Mr Shorten] is reduced now to personal attacks," Mr Turnbull said.

"This is a day and a time when Australians expect their leaders to focus on the economy, focus on their jobs, focus on their future.

"If Mr Shorten wants to engage in personal attacks then he can do so, but I won't be trading them with him."

Mr Turnbull on Friday moved to ease concerns, saying Australia's economy was well-placed to deal with the uncertainty.

"Australians, I recognise, will be concerned by the uncertainty and instability in global markets, falls in currencies, including the Australian dollar and in equity markets," Mr Turnbull said.

"It is important to remember that the Australian economy is strong and resilient, and has weathered global shocks before and weathered them well."

Uncertainty to continue: Turnbull

The Government and Opposition have received briefings from the Reserve Bank and Treasury, and Treasurer Scott Morrison said on Saturday he had spoken with bank CEOs.

Mr Turnbull said Australia's economy was fundamentally "very strong", but uncertainty caused by Brexit would continue for some time.

"Now more than ever Australia needs stable, strong economic leadership," he said.

"We have a clear plan, we are the only parties that have a clear economic plan and we are seeking the opportunity to carry that out over the next three years."

He said work would continue towards securing a free trade deal between Australia and the European Union and a deal would be reached with the UK.

"Because we have very strong relations with all of the countries of the EU and, in particular, the very strong support of Germany and France," he said.

"I have no doubt that we will be able to negotiate satisfactory trade arrangements with a separated Britain, absolutely no doubt about that whatsoever."

Brexit a 'victory for isolationism'

Meanwhile, Greens senator Sarah Hanson-Young attributed Britain's exit from the European Union to racism.

"The demonisation of people seeking asylum from the pro-Brexit campaign has been and was shameful, and what it shows is that the victory of the Brexit campaign is a victory for isolationism," she said.

"This was a vote based on nationalism and racism.

"While the Liberal Party has ultra-conservative elements in their ranks, we are at risk of that fear being peddled [in Australia]."
