What was Charles Perkins' role in the 'Freedom Rides' event? Why? What was the significance of Freedom Rides for Australia in post war...

Charles Perkins was the first indigenous Australian,
Aboriginal to graduate from University in Australia.  He was a noted soccer player and
was activist.  He spent his life working for rights for Aboriginal peoples.  There is an
extensive biography along with video on the website href="http://www.australianbiography.gov.au/subjects/perkins/">http://www.australianbiography.gov.au/subjects/perkins/. 
He has said so many important things it is hard to choose a specific quote that does
justice to the events of his life.

Inspired by the Freedom
Rides that were occurring in the United States in an attempt to force the integration of
interstate buses and bus terminals, Charles Perkins  and a group called the Student
Action for Aboriginals (SAFA) led a group of students from Sydney University for a bus
tour through rural New South Wales.  The objective was to expose racism against the
Aboriginals and draw attention to their poor living conditions.  They experienced
similar violence as did the protesters in the United States.  Their actions ultimately
led to a change in the laws regarding the treatment of the Aboriginals two years later
in 1967.
