Ted O'Brien said the Liberal Party needs to expand to better reflect modern Australia, promising to recruit more women and young people to help develop policies and represent parliament.

As the coalition’s long road to losing the March 3 election under Peter Dutton, new deputy leader and his leader Sussan Ley faced a call for formal quotas to help women occupy the winning seats and reset a major policy to better align with voter concerns.

Fairfax MP and nuclear power defense lawyer told Australia that he would contribute to the policy debate on energy supply, but stopped saying whether the Dutton era plans to build seven reactors should remain policy for the next election, around 2028.

"I absolutely believe we need to see a larger Liberal Party that reflects modern Australia and represents modern Australia, which includes more women, not only running for parliament throughout the party, but running throughout the party," O'Brien said.

“I feel sad that we have 28 female candidates, 28 women who participated in this election as unelected liberals.”

When asked about Dutton tagging ABC and Guardian Australia with “hate media” a few days before the election, O'Brien promised to take a different approach.

“I don’t believe in bias in any media.

“I think we need to talk to all Australians because the Liberals represent all Australians and different media sometimes talk to different parts of Australia.”

After Anthony Albanese violated expectations and significantly increased Labour's representation to at least 93 seats, the alliance looks to be reduced to less than 45 seats.

Ley and national leader David Littleproud have begun negotiations on a new alliance agreement, but she is working to name the front desk or take a view on policy details.

Angus Taylor, who voted 29-25 in the Shadow Treasury, said she wanted to meet with voters “where are they” and that the Liberals need to provide it to Australians.

O'Brien was first elected to parliament in 2016 - working in his family's flour mill and bakeries including throughout Asia and has been serving as a consultant. He and his wife have three children, including a 20-month-old child. He founded youth-centered nonprofit innovation and was former chairman of the Australian Republican movement.

He said he will bring a constructive and communicative leadership style.

“We lost the election, we have already conveyed a big message that the Liberals are entering the reconstruction phase and I think Susan will do a great job as our leader.

“I have characters to play in it, trying to help the team work together and bring us all together as we move forward.”

Senior party figures, including former minister Simon Birmingham and Senators Maria Kovacic and Linda Reynolds, called on the coalition to adopt formal gender quotas to promote female representation.

Labor took a similar move in 1994 and now has gender parity in the caucus and Albanys' second cabinet.

But O'Brien said he would not provide any view on any mechanism to expand diversity.

“The first step in this process is that we are going to listen to the Australian community and look at the data and evidence so that we feel very humble about it,” he said.

A formal review of liberal losses is expected, which may be led by the party elders.

Apart from the debate on nuclear energy, some national congressmen hope that the opposition will abandon its support for Purification by 2050.

O'Brien said he looks forward to talking to voters in new roles across the country.

"I believe in old school politics. I believe in street corners, town halls, footstep clubs, so when you're old school like you, you don't know who's going to rock and chat with you."
