My goodness no "canners" in Gawler? You really should get out more!
"The history of home canning dates back to early Mediterranean civilizations who dried figs in the sun and the ancient Egyptians who doused fresh herbs with olive oil. Home canning as we know it today came along in France in the early 19th century, when Nicolas Appert invented a way to safely store food by vacuum-sealing it in jars1. Home canning in the United States made a pronounced appearance during World War I, maintained a steady following through the Great Depression, peaked during World War II, suffered a substantial decline after the war, and has been regaining popularity since the 1970’s"
