Former Labor leader Bill Shorten says if he had his time again, he would take fewer messages to the election and better emphasise the jobs available in renewable energy.
Getting out ahead of the public release of a review of Labor's election campaign, Mr Shorten released a statement on Twitter saying the report should generate much debate and discussion within the party.
"There are many players on a team but as captain of that team I accept full responsibility for the policies taken to the election," he said.
"And while the review has not considered or reviewed the merit of those policies it is important that the party does.
"Were the universe to grant re-runs, I would campaign with fewer messages, more greatly emphasis the jobs opportunities in renewable energies, and take a different position on franking credits."
The review did examine the "relentless and unprecedented multi-million-dollar political attacks on me" by Clive Palmer and the Liberals that "successfully tarnished my public standing", he said.
"This is an important lesson for any future leader to confront."
Mr Shorten again indicated he intends to stick around politics, with the 52-year-old saying he was committed to continuing to contribute to public life "for the next 20 years".
