Prime Minister Malcolm Turnbull has urged his MPs to talk up the government's achievements.
Malcolm Turnbull says he's looking forward to Tony Abbott playing a "constructive role" and urged all coalition MPs to do more to talk up the government's achievements.
The prime minister and his predecessor are being urged by senior Liberal figures, including party president Nick Greiner, to meet as early as this weekend to resolve their differences.
Mr Abbott said in an interview this week he had not just a right but a duty to speak out where he thought it was important.
He has recently been vocal on the government's policy and direction, from submarines to climate change, which has fed into speculation about leadership tension.
The former leader will be backing an internal party reform program to be debated at a Liberal convention in Sydney on Sunday, which is at odds with an alternative plan being pushed by party moderates including Mr Turnbull.
The prime minister on Thursday said he looked forward to catching up with Mr Abbott soon.
He added all MPs needed to accept it was a "team business".
"I would rather that all of our members - without singling anyone out - focus on the extraordinary achievements of the government," he said.
Mr Turnbull will address the special party convention on Saturday.
Treasurer Scott Morrison, who will also be attending, declined to buy into which reform plan he would be supporting.
However, he said he was in favour of "democratisation" of the party.
"I don't believe it's my job as a parliamentary member of the Liberal Party to be going around lecturing the organisational wing about how it should conduct its affairs," he told reporters in Melbourne.
"I'm a fierce defender of the organisational wing of the Liberal Party to make decisions on the issues that are within its domain."
Two federal Liberal MPs, Alex Hawke and Julian Leeser, are crunching the numbers on a series of motions which would head off the push led by Mr Abbott for a deeper overhaul of preselection rules.
