Australia's incumbent Prime Minister says we may not know the outcome of tomorrow's federal election, if polls are anything to go by. 
ABC political reporter Brett Worthington told Heather du Plessis Allan Scott Morrison still hopes he'll again defy the polls.  
“Both sides of politics are suggesting that Labor is in front but Scott Morrison has been coming home like a steam train which is his typical leadership style, so he is hoping that can get him over the line.” 
Worthington says by tomorrow, half of Australians will have already voted.
