ok. Well firstly I don’t think that the survey results you posted along with the question necessarily relate to women MPs. It could just be that Australians prefer a two party system. In nz when MMP was introduced there were also concerns that it would destabilise politics. So possibly more a deeply entrenched belief system and attachment to the past.
however that said Australians have always seemed to me to be a pretty sexist and racist society so maybe your interpretation is right and that underlying those results is a sexist view of politics which is merely an extension of that more general view. Where that problem comes from is I guess a matter of conjecture but I think that modern australia had its foundations in a hierarchical, patriarchal power structure. Founder cultures are incredibly hard to shake off.
