Winner of most Australian Open women’s titles?

Question

Margaret Court is the clear winner here. The Australian won 11 titles in total, seven before the Open Era began in 1969, and four from 1969 onwards. In the Open era, Court’s four titles are equalled by Evonne Goolagong Cawley, Steffi Graf, Monica Seles and Serena Williams – who as the only current player among the group could take the Open Era record as early as 2010.
