Senator DI NATALE (Victoria—Leader of the Australian Greens) (11:59): I seek leave to make a short statement. The PRESIDENT: Leave is granted for one minute. Senator DI NATALE: I commend Senator O'Sullivan for his support of childhood immunisation—it is indeed one of the most effective ways of preventing childhood diseases, and it is something that I have spoken about in this chamber many times. There is no stronger supporter of childhood immunisations in the Australian parliament than me and the Australian Greens. What I object to is that this motion condemns an entire branch of the Greens for the statements of several individuals. It is true that there are several individuals within the Townsville Greens—as there are within every party—who have concerns about immunisation; but we do not put motions to condemn an entire political organisation. We do have people on the fringes in our party, but the difference between our party and the Liberal Party is that you have them in the parliament. Look at Cory Bernardi—a case in point. Question agreed to.
