Victoria's new women's minister says it would be naive to think equal gender representation could be achieved in Parliament because women are generally ''nurturers'' and politics is demanding.

As the Liberal Party conducts a review designed to get more women preselected, Liberal MP Heidi Victoria has also declared she does not support affirmative action quotas - a system that has helped the proportion of Labor women to rise from 14.5 per cent to around 38 per cent within two decades.

In an interview with Fairfax Media, Ms Victoria said it was important to encourage women to get involved in politics, but added that achieving gender equality was probably unrealistic.

''By our nature, obviously women are the nurturers in more circumstances than not, so for us to say that there's going to be equality in Parliament is perhaps naive. Not every woman wants to be in that situation,'' said the Bayswater MP, who balances her job with being a single mother.
