Deputy Prime Minister Michael McCormack has thrown his support behind overhauling Nationals rules to guard against leadership coups.
Mr McCormack believes the Nationals should follow the lead of the Liberals to protect federal leaders who are involved in winning elections.
"I think for the sake of stability, yes. I think for the sake of consistency it would be something that would be very good," he told AAP on Monday.
In December, Prime Minister Scott Morrison made it harder for his party to dump leaders who win elections.
Under the updated rules, the support of two-thirds of the federal Liberal party room is needed to make a change - a near impossible threshold to reach.
"The revolving door of prime ministers has to stop. It does," Mr McCormack said.
"I'm glad the Liberals have put in place a mechanism. I just think people are crying out for stability."
If the coalition wins on May 18 and the Nationals change party rules, it would guarantee Mr McCormack, who has faced leadership speculation during his 14 months in the job, the leadership for the next term.
The deputy prime minister, who is a former newspaper editor and journalist, said the media at times irresponsibly reported on leadership stories.
"Sometimes when there is a little bit of speculation helped by the media throwing fuel on to what is just a little bit of a flicker of a flame, it can develop into a wild bushfire overnight," he said.
"It might just be one person or one aggrieved staffer who can start something off like this and then it becomes a major issue that is distracting from the overall message."
Mr McCormack said people in the "real world" were busy paying bills, looking after their children or enjoying retirement.
"They just think Canberra is a complete circus - it's not."
He said while he understood they were good for boosting reader numbers and ratings, leadership stories could overshadow Australia's democratic system.
During his second crack as prime minister, Kevin Rudd changed Labor rules so leadership contenders have to gain a majority of votes in the caucus and in a grassroots party ballot.
"Wouldn't it be good to see a prime minister get elected and serve out their term?" Mr McCormack said.
