First, may I acknowledge and warmly welcome the First Nations students participating in the WEX program who are here today in the gallery—particularly those from South Australia! Welcome to all of you, but particularly those from SA!

Senator Ruston, can I say, first in relation to the comments you've referenced, that they are completely unacceptable. I say that today, and I understand that the Prime Minister has made that clear. In relation to Mr Muldoon's employment, Senator Dowling has taken immediate action, as is appropriate.
