Architect of Labor election win to reveal victory path

The mastermind behind Labor's decisive election victory will lay out how the party secured one of biggest wins in history.

In an address to the National Press Club on Wednesday, Labor's national secretary and campaign director Paul Erickson will say the government's economic narrative and ability to adapt was crucial to its expanded majority.

Labor boosted its ranks to have at least 93 seats in the next parliament, one of its largest majorities in history, with Mr Erickson credited as the architect behind the result.

"The conventional wisdom undervalued Labor's capacity to use our record as the foundation for our second term policy offer," he will say in the speech.

"Over three years, Labor's record and Peter Dutton's opposition built up an advantage for Labor as the best party to provide cost-of-living relief."

The speech as comes as Prime Minister Anthony Albanese arrived back in Canberra on Wednesday after a successful overseas trip to Indonesia, the Vatican and Singapore, where he met with the Pope and other world leaders including Ukrainian President Volodomyr Zelenskiy.

Mr Erickson said the key to the election success was using Labor's first term in office to sow the seeds of long-term reform and cost-of-living help.

He said it stood in contrast with the promises of former opposition leader Peter Dutton, who ended up losing his seat in the election.

"When it came to the campaign, Peter Dutton said that Australians would have to wait until after the election to find out where a Dutton government would cut," he will say.

"Instead of campaigning on the details of his plan, he left a vacuum."

Many commentators had written off Labor's chances of forming a majority at the start of the year when the coalition were ahead in the polls.

However, Mr Erickson said Mr Albanese and Labor were able to adapt to challenging conditions, such as the imposition of tariffs by US President Donald Trump or the impact of Tropical Cyclone Alfred.

"The contrast was as clear as night and day. The prime minister offered authentic, measured and firm leadership, and Peter Dutton never missed an opportunity to miss an opportunity," he will say.

"While the prime minister was telling a positive story about who we are and where we're going, Peter Dutton was gloomy about the country, downcast about the future, and most animated when magnifying the problems facing Australia."
