Mr TURNBULL (Wentworth—Prime Minister) (14:14): Mr Speaker, if even John Setka doesn't trust the Leader of the Opposition—and he pays for the campaign of the Labor Party; he's the principal funder, the controlling shareholder and the primary financier of the Labor Party—why would any Australian voter or Australian worker trust the Leader of the Opposition? How could you trust the Leader of the Opposition, with his rolled-gold guarantees? It was not so long ago that there were a few more faces sitting opposite, Mr Speaker. They were apparently rolled-gold guaranteed to be eligible to sit here. Well, they've all had to resign. The fact is that the Leader of the Opposition cannot be trusted on one promise at all. This is a man who seeks to be Prime Minister; who stood at this dispatch box and said, 'Lower company taxes deliver more investment, greater productivity, more jobs and higher wages.' Great stuff! Did he believe it then? Who knows? Does he believe what he's saying now? Who knows? John Setka doesn't know—nobody knows. He cannot be trusted— The SPEAKER: The Prime Minister will resume his seat. The Leader of the Opposition on a point of order. Mr Shorten: On direct relevance. Why won't the Prime Minister answer the question on why he won't support Labor's almost double income tax cuts compared to his own? The SPEAKER: The Prime Minister has concluded his answer.
