An institution at many pubs, restaurants, and cafés in Australia, Australian burger with the lot first made its appearance in the 1940s, when beetroot started to be added to the burger alongside onions, tomatoes, lettuce, and meat.
The inclusion of canned beetroot on a burger was possible due to the fact that there were two canneries that opened during the 1930s and the 1940s. Today, there is still a heated debate about the inclusion of beetroot - some say it is obligatory, while the others claim it's a travesty.
