Malcolm Turnbull's post-election ministry is expected to include conservative rising stars and younger women.
But Cabinet Secretary Arthur Sinodinos expects the prime minister will be able to straddle the liberal and conservative elements in his party.
Mr Turnbull will have to replace at least two ministers after Wyatt Roy and Peter Hendy lost their seats.
He may also lose Tourism and International Education Minister Richard Colbeck, who was fifth on the Liberal Senate ticket in Tasmania.
Senator Sinodinos said while ultimately it was up to the prime minister to choose ministers, there was a good stream of younger talent within the party.
"We also have to make sure we continue to develop our younger women ... because it's important to have that group of women who can come through and into cabinet," he told ABC TV on Sunday.
Senator Sinodinos would not be drawn on whether Mr Turnbull should promote his predecessor, saying only that Tony Abbott had played as a team member during the campaign.
Immigration Minister Peter Dutton has been tipped to return as a permanent member of the national security committee as Mr Turnbull seeks to placate the party's right.
"The prime minister is aware that he straddles both the small-l liberal and small-c conservative wings of the party and his job is to bring them together," Senator Sinodinos said.
"He will show that in the period ahead."
Mr Dutton publicly swung behind Mr Turnbull and deputy Liberal leader Julie Bishop on Sunday, saying the primary objective for the government was to provide stability.
"The best way we can do this is to provide support to the current leadership team and all of us across the spectrum of the party must pledge our support to Malcolm Turnbull," he told the Sunday Telegraph.
But he was concerned about the party's ability to move quickly during the campaign in the face of a backlash on superannuation changes and efforts from campaigners like GetUp and the unions.
Liberal senator Cory Bernardi wants to establish a conservative movement to counter GetUp.
He was in a good position to balance considerations of running an organisation that was both within the party and outside it, Senator Sinodinos said.
