Labor leadership hopeful Bill Shorten has paid tribute to his opponent Anthony Albanese for the civility of the pair's contest ahead of a caucus ballot.
Mr Shorten arrived at Parliament House on Thursday afternoon ahead of the caucus meeting at 4pm (AEDT).
"This process has gone a long way towards healing some of the previous divisions in the Labor Party," he told reporters.
"Normally when you lose an election there tends to be a bout of recriminations and a blame game, hopefully in this process we've moved to absorb the lessons from the Australian public."
He praised Mr Albanese for the "civil campaign" he's conducted.
Mr Shorten said he felt encouraged by the positive response he's received from branch members and conversations he's had with parliamentary colleagues.
Asked if MPs would be voting along factional lines, Mr Shorten said he expected MPs to vote according to what they thought was in the best interests of the nation and the party.
He supports the caucus picking the frontbench line up and the party leader allocating portfolios.
"I believe that Labor works best when we invite members of our caucus to have say in the running of our parliamentary team," Mr Shorten said.
"As to who gets chosen for the frontbench, that will be a matter for caucus."
The winner will be known on Sunday after the results of a rank and file ballot are compiled and combined with the caucus vote.
