The final week of election campaigning in Australia has begun, with Brexit at the forefront of discussions.

Voting will begin on Saturday and as both sides wind up their campaigns the polls are leaning slightly to Labour.

Prime Minister Malcolm Turnbull is vowing to prioritise talks with New Zealand on maximising opportunities - if his coalition is re-elected.

But Donna Demaio told Rachel Smalley opposition leader Bill Shorten is using Brexit to highlight his opponent's weaknesses.

"So there's still a lot of disunity in the wake of what happened with Tony Abbott, the former leader. He's saying that he's a weak man, and he says it's a major lesson of the Brexit outcome in the UK is you need to elect a government which can deliver stability and unity."
