Mr VASTA (Bonner) (14:56): My question is to the Minister for Education, representing the Minister for Employment. Ms King: Madam Speaker, on a point of order: the Treasurer made a most unparliamentary remark at me. I would ask him to withdraw it. Mr Hockey: I did: I called them hypocrites. I withdraw. The SPEAKER: Quite right; it is unparliamentary. Mr Burke: Point of order, Madam Speaker: if anyone from our side did exactly that, you would have ejected them. You would have done that for any one of us, and you would have been right to do so, Madam Speaker. The SPEAKER: The Manager of Opposition Business is tempting me. The Treasurer has used the word 'hypocrite'. It is unparliamentary and he has withdrawn. The member for Bonner has the call. Mr VASTA: Thank you, Madam Speaker. My question is to the Minister for Education, representing the Minister for Employment. Honourable members interjecting— The SPEAKER: There will be silence! The member for Bonner will begin again. Mr VASTA: My question is to the Minister for Education representing the Minister for Employment. I refer the minister to the Royal Commission into Trade Union Governance and Corruption. Why is it necessary to ensure the highest levels of probity in the union movement in Australia, particularly given their historic links to registered organisations?
