Labor leader Bill Shorten has promised to be the first opposition in federal election history to release their budget costings more than a week before the poll.
Mr Shorten and Prime Minister Scott Morrison went head to head in an hour-long televised event in Brisbane on Friday night, in front of an audience of 109 undecided voters.
The Opposition Leader was declared the winner of the second leaders' debate by a slim margin, days after he was also declared the winner of the first one in Perth on Monday.
Forty-three audience members said they were more likely to vote for Mr Shorten as opposed to 41 who said they favoured Mr Morrison. Sixteen said they remained undecided following the debate.
Earlier in the night, Mr Shorten was asked about the cost of his policies and how he would afford them and he revealed all the costings will be announced next week.
