Point of order: I draw your attention to standing order 193(3), which states:

A senator shall not use offensive words against either House of Parliament or of a House of a state or territory parliament, or any member of such House, or against a judicial officer, and all imputations of improper motives and all personal reflections on those Houses, members or officers shall be considered highly disorderly.

I suggest that some of what Senator Henderson is saying right now contravenes that standing order.
