Australian Prime Minister Anthony Albanese has come out on top in the first debate of the election.  

Of the 100 undecided voters polled after the debate, 44 chose Albanese, 35 chose his opponent Peter Dutton, and 21 were undecided.  

Australian correspondent Steve Price told Mike Hosking a personal tragedy struck Dutton shortly before it started.  

He says Dutton received news his father had had a heart attack an hour before the debate started.
