Author Larry Writer speaks to John Stanley about his new book The Shipwreck, which is an epic story about one of Australia's greatest maritime disasters, the wreck of the Dunbar.

Larry's book illustrates how late at night on 20 August 1857, after an 81-day voyage from Plymouth, the Dunbar was caught by massive waves and storm-force winds near the cliffs of The Gap at Sydney's South Head and smashed to pieces on the rocks. All but one of the 123 passengers and crew perished.
