The were only about 100 at counter protest. There is no way, none whatsoever that there were 15,000 at the Adelaide rally. The cops are having a laugh, or deliberately overestimated crowd size to boost the number of people at the main march because they support it, or did not factor in the distance between protestors because they were all spread out so as not to hit each other with all the Australian flags they were carrying (there were so many big flags they all had to give each other wide berths).

There were a lot of protestors at the main march, just nowhere near 15,000.
