A survey conducted by the IPSOS Mackay, covering 1047 people, found 19 percent of women strongly agreed, and 43 percent somewhat agreed with the proposition that "generally, men and women are not treated equally in Australia".
Ten percent of men strongly supported the proposition, while 37 percent agreed "somewhat" with the question, The Age reports.
Queensland Premier Anna Bligh and Governor-General Quentin Bryce rated relatively highly when respondents were asked which Australian women "best represent Australian values".
Fourteen percent of Australians believed Bligh best embodied national values, slightly trailing swimming champion Dawn Fraser with 15 per cent.
Bryce ran third with 9.7 percent votes, while seven per cent of people said solo teenage sailor Jessica Watson best represented the nation's values. Prime Minister Julia Gillard was at fifth place with 7.6 per cent votes.
