The International Day of the Unborn Child will be marked around the world this Sunday, March 25, the Feast of the Annunciation.
In Sydney a march through the city streets is expected to attract more than 3,000 people.
Paul Hanrahan, the campaign director of 40 Days for Life in Sydney, told Cradio why this day is so important, how it all started, and why every Catholic in Sydney should be there.
