Just before 10am on Friday, Audrey Blair and her friends, one of them still carrying his blanket, were ordered out of Brisbane's central square.

It was nothing new for the handful of homeless young people, part of a dozen-strong group aged between 12 and 20, and used to police telling them to move on.

Police move a group of homeless young people on from King George Square in Brisbane.

The one thing different about Friday was the justification. Half a dozen police, some of many brought in from throughout Queensland told them they had to make way for the Duchess of Cornwall, Ms Blair said.

“It's like they're trying to make everything look perfect,” she said.
