A WELL-KNOWN Aboriginal activist has been arrested by police in Sydney for staging a protest against King Charles’s visit to Australia.

Wayne ‘Coco’ Wharton stood opposite crowds hoping to catch a glimpse of King Charles and Camilla during their visit to the Sydney Opera House on Tuesday afternoon.

However, before the royal couple arrived Wharton began shouting anti-monarchy slogans.

“He is the king of thieves and the king of liars,” he said.

"He's not my king. You have the blood on your hands of invasion. You are a nation of thieves!”

Shouts of "God Save the King” could be heard amongst the crowd gathered to see King Charles in reply to Wharton’s protest.

After appearing to agree to leave the scene peacefully, Wharton changed his mind after a police officer touched him.

He was then arrested for allegedly refusing a police order to leave the area.

It marks the second day of protests on King Charles’s first visit to Australia since his coronation.

On Monday, Senator Lidia Thorpe interrupted his speech in Australia’s Parliament House in Canberra to accuse him of “genocide”.

While on Tuesday morning a statue of Queen Victoria in Sydney was vandalised with red paint.
