Where else would you find National Party senator Barnaby Joyce, former NSW ALP treasurer Michael Costa, and Professor AJ Brown, a constitutional lawyer who, in his own words "might vote Green" all arguing on the same side of an issue? At an IQ2 debate.
The proposition they all agreed upon? That State Governments should be abolished. Perhaps a controversial position to take, especially for a former senior state government politician. Arguing against this unlikely alliance were two experts on Constitutional law, Professor Anne Twomey and Professor Greg Craven, and Former Premier of Western Australia, Professor Geoff Gallop.
