Senator Sterle, you seek of me a knowledge of the intricacies of Western Australian upper house politics that, I am afraid, I do not possess. Suffice it to say, in the lower house, where it matters, where governments are formed, the Liberal Party and the National Party will be preferencing one another in every seat. In relation to the recondite science of preferences in the upper house, it is a matter for the state executives of the respective parties to make their own determinations.
