At least five protesters have crashed Chinese ambassador Xiao Qian's speech at a Sydney university.
Minutes into an address at the Australia-China Relations Institute at the University of Technology Sydney, Mr Xiao was interrupted by protesters on Friday.
They shouted about the large scale detention of the Uyghurs, a minority ethnic group in China's northwestern province of Xinjiang.
"You're a disgrace," a protester shouted.
"What about freedom of expression."
Anti-Chinese Communist Party activist Drew Pavlou was removed from the event, after holding up a sign which read "Free Tibet".
The university cut the online feed of the address several times during the interruptions.
