Australian women politicians

While sitting around and musing about the performance of Prime Minister Julia Gillard, I got to thinking about the standard of senior women politicians in recent political history, and I've come to the conclusion that it's a pretty embarrassing state of affairs.
I won't add any new polemics about Gillard, other than to repeat that she's not up to the job. But what of the others? Unfortunately the only word that readily comes to mind is failure!
So lets have a look at who else has made a name for themselves in the not too distant past;

• Ros Kelly....of the famous whiteboard incident......enough said
• Carmen Lawrence....the former WA Premier (allegedly) perjured herself on the stand, not to mention having the death of Penny Easton on her conscience for the rest of her life Easton affair
• Bronwyn Bishop...the Minister for "kerosene baths" and other assorted embarrassments
• Julie Bishop...the current Deputy Leader of the Federal Liberal Party, who seemingly can't be sacked from that position regardless of how many times she embarrasses herself, due to her power base in WA
• Joan Kirner...the much ridiculed former Victorian Premier, who's probably better remembered for this performance on The Late Show
• Cheryl Kernot...former Leader of the Democrats, who had delusions of grandeur of becoming PM and switched to the Labor Party, where she humiliated herself on a daily basis.....but at least she had the loving arms of the married Gareth Evans to help sooth the pain
• Anna Bligh...the current QLD Premier....showed some leadership during the floods crisis, which did no more than disguise her other failings. But the polls are now back on track to show an humiliating defeat for Labor at the next election

So have I overlooked anyone? Unfortunately there is just not alot to show for 100 years of the suffrage movement in Australian politics. Other western democracies can seem to produce quality female politicians, so what's wrong with Australia?
