Speaking on Sky's Speers on Sunday, Labor's shadow employment minister Brendan O'Connor said all the policies the party took to the election it lost should be under review.

But he said voters would not believe what Labor had to say in future if it completely changed its policy agenda.

"It would be incredible for a Labor Party to abandon its policy prescription entirely, because no one would believe what you say if you jettisoned all of your policy pronouncements," Mr O'Connor told Sky.

He said Labor's policies identified structural problems in the economy and the environmental challenges facing the country.

Mr O'Connor says Labor's review of the election, which is due to be released as early as Thursday, should "draw a line in the sand" and allow the party be move forward.

He said the review should be made public.

But he also warned against the party perceiving May's result as a landslide - the coalition only has a one seat majority in parliament.

"The election was close, it was just a shocking result because of the expectation," Mr O'Connor said.

He said the Greens had taken votes away from Labor and the party needed to focus on looking after workers and their families.

Mr O'Connor also pointed to Labor leader Anthony Albanese's speech on Tuesday, in which he said coal still had a manufacturing future in Australia and could be used to build green technologies.

Mr O'Connor said it was not a "binary choice" between renewable energy and coal.

He also said mines which "ticked the regulatory boxes" should be given the green light, something Labor should have been clearer about at the last election.

"We should be using our resources, our traditional industries should be supported," Mr O'Connor said.
