>If you have seen/heard the videos (the one I watched was posted on X/Twitter on the 10th October 2023), it is quite obvious that the protestors shouted "gas the Jews" multiple times and it is absolutely extraordinary that anyone would claim otherwise.

The point is that those videos were almost certainly doctored to add that audio, almost certainly by the entity that claims responsibility for promoting the video, the AJA. That chant would have been a crime in Australia, so it became a police matter, and after investigating the video they found it didn't contain evidence of that crime. There were anti-Semitic chants at that rally (which were immediately and fully condemned by the organisers of the rally, who are good people, not anti-Semitic in the slightest, and who work with Jewish people constantly in their anti-Zionist activism), but there is no evidence that the specific chant the AJA alleged and provided likely falsified footage for was one of them.
