Former treasurer Wayne Swan says he'll keep his seat, but has refused to say who should lead the Labor party in opposition.
Mr Swan says Labor's policies saved Labor from further losses, particularly in Queensland.
When asked about the Labor leadership going forward, he said he wasn't about to talk about internal matters when that's what had cost the party so dearly at this election.
"We've been punished for those divisions," he told the Seven Network.
He said Labor must conduct a mature election post-mortem.
"In this election campaign and in the last few years there has been too much concentration on divisions and not enough on the policy way forward," he said.
Mr Swan wouldn't be drawn on whether the party was right to dispose of Julia Gillard.
"I'm not going to get involved in that sort of debate. We've had too much of that over the last three years and we have to move on.
"We've got to be mature in our analysis of what went right and what went wrong."
