Body blocking and use of red flags to shut down peaceful appeal to China's Premier

Body blocking and use of red flags to shut down peaceful appeal to China's Premier to stop persecution of Falun Gong and stop forced organ harvesting in China on Saturday June 15,2024 at Continental Hotel North Terrace Adelaide.
The pro-CCP Chinese students and Chinese Australians has trampled on the basic rights of Falun Gong practitioners to peacefully protest and infringed on the freedom of speech and expression.
Is this legal on Australian soil? How can these people be so outrageous and why are there no consequences from the authorities on their rogue behaviour?
