Labor frontbenchers are looking at what lead to the party's shock election loss, with one saying they need to examine why people were open to a scare campaign.
A Labor frontbencher says her party scared people at the federal election but also needs to look at why voters were open to fear campaigns around its policies.
Catherine King says the party has to accept responsibility for its loss at the May 18 election and it should take its time with the post-mortem.
"We scared people, basically, I think," she told ABC radio on Friday.
"And particularly we scared people in our working class and lower-income areas and we have to understand what that was and ... why we weren't getting our message through."
But she also said scare campaigns like those run against Labor only worked when there was a receptive audience.
Bill Shorten, who led the party to defeat when all the polls pointed to a Labor win, has blamed "corporate leviathans, a financial behemoth ... telling lies, spreading fear" for the loss.
New Labor leader Anthony Albanese agrees "vested interests" had a hand in the election loss.
"There is no doubt that vested interests did play a role," he told Nine's Today program.
"But we also have to accept our responsibility that some of the policies that we put forward clearly didn't connect with enough people."
Liberal frontbencher Simon Birmingham said Mr Shorten was "delusional" and cautioned Mr Albanese against adding the ex-leader to his shadow cabinet - something the caucus has already decided will happen.
"You might forgive a bit of bitterness but he doesn't seem to understand or have heard any of the messages," Senator Birmingham told Today.
He pointed to the Liberal Party's own negative experience in having former leaders - like Tony Abbott - in the parliament, saying "things are smoother, perhaps when you don't have some of those".
Mr Shorten on Friday used Twitter to reject as "just wrong" claims made in The Sydney Morning Herald and The Age that he still harboured leadership ambitions.
"I have and will work hard every day to keep our party united and make the case for Labor under Albo's leadership at the next election," he said.
But senior Liberal Mathias Cormann thinks that's rubbish.
"Do you think that a fish stuck on land wants to get back into water," he told Sky News.
"I think that everyone in the parliament knows that if there was an opportunity for Bill Shorten to get the leadership back he would go for it.
"I don't even think that is particularly remarkable."
Mr Albanese is preparing to allocate portfolios for his shadow ministry, which is expected to be announced over the weekend.
