The author seems to be pulling things out of context in bad faith. It is unlawful, though not a criminal offense, in Australia to publicly say things likely to offend people of a different race, based on their racial group, provided the statements are not meant "(a) in the performance, exhibition or distribution of an artistic work; or (b) in the course of any statement, publication, discussion or debate made or held for any genuine academic, artistic or scientific purpose or any other genuine purpose in the public interest; or (c) in making or publishing: (i) a fair and accurate report of any event or matter of public interest; or (ii) a fair comment on any event or matter of public interest if the comment is an expression of a genuine belief held by the person making the comment." (as explained in 18D).
