Ms Harvey said people must be promoted on merit, not on the basis of a required number, after the Federal Labor Party announced it would aim for half of parliamentary seats to be filled by women within a decade at its National Conference last month.
"We should encourage and support more women to consider a political career and crucial to this are mentors who can guide women through their political career," Ms Harvey said.
"Resolutions at State and Federal level are being made that will affect all Australians and to have a fair representation of our diverse groups is important to ensure positive outcomes."

READ NOWFederal Labor deputy leader Tanya Plibersek announced last month the party had committed to the 50 per cent quota.
"Women are half the population and they should make up half of our parliament too," she said.
Ms Harvey said she had never felt as though there were barriers in her political life due to her gender.
"In my various parliamentary roles, I discuss with young women I meet that pursuing a political career is a challenging and rewarding one," she said.
Liberal Party state director Ben Morton echoed Ms Harvey's comments last week.
"Interestingly, the last three pre-selections in the Liberal Party in WA have resulted in the selection of women, not men, and all on merit."
