Food preservation has been a major challenge throughout Australia's history. In Victoria James Harrison invented a process of refrigeration that could make artificial ice on a commercial scale. In New South Wales, Thomas Mort and Eugene Nicolle, adapted and improved on Harrison's technology to build the world's first freezer works to produce artificially frozen food . In Western Australian Arthur McCormick came up with the Coolgardie food safe that ran on evaporative cooling, and in South Australia Tom Angove invented the wine cask.
