Reduce Prime Minister's Pay to Reduce Struggle Incentive

Well it looks like Prime Mister Tony Abbott, a man who couln't shut up about the supposed damage caused to Australia by the previous government's leadership struggles is about to go down to a leadership challenge in his own party.  Yes, it is poetic, but it is hardly surprising since despite apparently being obsessed with the issue he never actually did anything to reduce the likelyhood of leadership struggles in Australian politics.  Surely if he was serious, his first initiative in government should have been to reduce the Prime Minister's pay down to that of a backbencher in order to remove one of the incentives to struggle for leadership?
