Aboriginal activists stage royal protest

About 30 Aboriginal activists are staging a protest at South Bank, where the Duke and Duchess of Cambridge are due to arrive soon.

The protesters are gathered at the park precinct, where the couple is due to attend a civic reception before a brief public walk later this afternoon.

"Always was, always will be Aboriginal land," the protesters chanted.

One held a yellow placard that read: "Give back what is ours."

Police told AAP a small number of Aboriginal protesters had been moved on at South Bank.

One activist was ushered away after going behind barricades meant to keep the royal route along Grey Street clear, outside the South Brisbane train station.

No arrests have been made.
