Amongst the chaos, an ABC cameraman was pushed by a man who then appeared to attack his gear. A woman, Camie, 30, was violently shoved by pro-Chinese demonstrator, who subsequently had his hair pulled by protesters on the other side and was forced back into his group. Camie, who was stunned but otherwise unhurt, said she was protesting in solidarity for the people of her home city. "I'm from Hong Kong. It started (the rallies) because of the extradition bill but now we don't have democracy. We have come to save our city," she said. Police appeared to be caught unaware by the scale of the protest and only intervened when pro-Chinese demonstrators surged towards the pro-Hong Kong side. By this time, scuffles had been breaking out for about 40 minutes.

This shut down flare-ups of aggression, save for a small fight near the La Trobe St intersection. Police moved in quickly and took one man away.

The number of pro-Chinese protesters surged throughout the evening and eventually outnumbered, and out-voiced, the pro-Hong Kong side. By 9pm, several hundred protesters, mostly supporting China, had also gathered on the west side of Swanston St. On the library side, they sang their national anthem, chanted in Mandarin and English for “one China” and let the protesters know they were “rubbish” and that “China is great”. They were reluctant to give names or speak on the record, however one said he was there because “I’m from China and Hong Kong is part of China. One China.”

Under the gaze of the statue of Sir Redmond Barry, Hong Kong protesters gathered on the north side of the library lawn, singing and chanting “free Hong Kong”. A pro-China demonstrator yelled out “if you don’t like it, leave the country.” Another yelled back “we’re in Australia." After more than two hours of tension, many of the Hong Kong protesters started to leave, but pro-China protesters remained in large numbers, chanting. By 9.30, police had begun pushing the groups further apart until most began to disperse.
