Aboriginal tent embassy marks 40 years

It is 224 years since the face of Australia changed forever with the arrival of the First Fleet.

It is 40 years, as of Australia Day, since, as some see it, the descendants of the Indigenous people who inhabited the land for tens of thousands of years truly started fighting back.

This week in Canberra, the men and women who made that stand - and their cause - are back in the spotlight.

Ron Sutton has the story behind the most unusual embassy the nation's capital has ever seen.
