Mr BROUGH (Fisher) (14:33): My question is to the Minister representing the Minister for Employment. I refer the minister to the report in the Herald Sun on 17 March revealing that the building industry whistleblower Andrew Zaf was stabbed outside his home. I also refer him to a separate incident reported in The West Australian in which the CFMEU's Joe McDonald put a worker in a headlock and threatened to hit him. How do these instances underline the importance of the government's plan to protect workers?
