The new year rings in a change in Australia's national anthem. No longer will it refer to Australia as "young and free." In an effort to pay homage to the country's long indigenous history, the words have been changed to "one and free." When Prime Minister Scott Morrison made the announcement on Thursday, it came as a welcome surprise. "It recognizes the distance we have traveled as a nation. It recognizes that our national story is drawn from more than 300 national ancestries and language groups and we are the most successful multicultural nation on earth," he told BBC News.
