The deputies of the coalition are moving away from the quotas to boost female representation in their federal party, leaving the door open to get there by other means.
Liberal MP Trent Zimmerman argues that the coalition needs more structures, mentors and training to get more women involved in politics.
"While I do not support the quotas, it is worthwhile for the party to set goals so that we can measure our success," he told ABC on Saturday.
"And that becomes a measure of performance, a KPI (key performance indicator), against which we can be judged."
He said that the objectives were aimed at locking a certain proportion of male and female deputies, while the quotas gave a "boost" to the candidates during the preselection.
Only one in five federal deputies within the coalition are women, compared with almost half in the opposition ranks.
"I do not think we're in the right place until we have parity," government leader Greg Hunt told Nine News.
Julie Bishop calls intimidation in the Liberal Party.
"That's 50 percent, plus or minus five percent in any direction over time because these things come and go."
The Nationals parliamentarian and government minister Darren Chester acknowledged that their party needed to encourage more women to participate in politics.
"I'm not a big fan of quotas, but I think we have to look more actively to recruit women to be safer," he told ABC.
"I think that parliament is better when there is more diversity, and there is a challenge on our side for that to happen."
But the quotas were the answer for Labor deputy Linda Burney, recognizing that she was a beneficiary of that policy.
"One of the reasons why the Labor Party is almost 50 percent is exactly because of the affirmative action policies," he said.
"Something deliberate like quotas or affirmative action is the answer, in my opinion, to bring some equity in terms of numbers."
