This is the best summary I could come up with:

Prime Minister Anthony Albanese has condemned the actions of protesters outside a major No campaign event in Adelaide, calling for a respectful debate.

About 20 protesters gathered outside the Adelaide Convention Centre on Monday night holding signs reading "fight racism" and "no pride in genocide" while chanting "always was, always will be, Aboriginal land".

South Australian Liberal Senator Alex Antic posted a video to social media platform X (formerly Twitter) which appeared to show him being heckled by the crowd.

At least one person could be heard yelling abusive phrases as Senator Antic walked past, including the word "racist".

"I've never persuaded anyone by calling them names, so it's crazy stuff, and I certainly don't think it reflects where the majority of Australians are at in the course of this debate."

Coalition Senator Jacinta Nampijinpa Price told about 1,000 attendees of the event that Indigenous supporters of the No campaign were being singled out for their stance against the Voice.
