In Adelaide, the organiser of the city's August March for Australia event, Mark Aldridge, was out on the streets once again, but this time joined the counter protest.

He told the ABC it had become clear to him that the March for Australia rally had racist overtones, which he disagreed with.

"The initial rally when I got involved was meant to be about the lack of supply of services for the migration numbers they were bringing in," Mr Aldridge said.

"I tried to send that messaging, it was very quickly assessable that that wasn't the messaging that was meant to be on the day."

The August rally ended after an altercation broke out when a man who identified himself as a member of the National Socialist Network took to the stage to call for an end to immigration.
