This day is celebrated across Australia as Mother's Day. The tradition of giving gifts on Mother's Day in Australia grew up in the 1920s after the practice had arisen in the USA several decades earlier. In Australia, Mother's Day has become a common occasion for family re-unions - second only to Christmas as a popular date for such an occurrence. It is also a popular practice to wear a white flower in the lapel on this day - particularly a chrysantheMUM.
