My memories of the last hung parliament was a a government having to make a case for all legislation to the cross-benchers and getting a hell of a lot of legislation through, despite the noisy interference of the Opposition who said no to everything.

Sure Gillard went back on a election promise, as a negotiation with the Greens.

But Abbott as PM went back on plenty of election promises off his own bat and under no pressure from anyone bar the ACL, IPA and the Australian Business Council - groups not elected to Parliament by the people, as the Greens were.

Not sure what Slipper and Thomson have to do with it being a hung parliament. except that the opposition were trying to influence the numbers in the Parliament against the will of the people.

David,

Gillard gave an iron clad guarantee that there would be no carbon tax and did exactly the opposite 3 weeks later. She also did not keep a single promise, and spent 3 years legislating an essentially green's agenda.

The Thomson saga was initiated by Fairfax which is a labor supporter, and made worse by Gillard's fierce defence, and the Slipper saga was started by Gillard's duplicity.
