'“No-Platforming” has increased in prominence within Australia in recent years. Furthermore, it has moved from university campuses to more mainstream sectors of the Australian public sphere. The “no-platforming” of an audience member on an ABC current affairs programme in March 2022 is evidence of this. By focussing on the arguments for and against no-platforming, as well as this incident, this article seeks to show their wider significance for no-platforming in Australia, and the implications of this for freedom of speech within the Australian public sphere.'
