Marketinfo says: "The two most important events in all Aussie history were the invention of beer and the invention of the wheel."
Aussies didn't invent beer or the wheel, but we did invent the first concentration camp in history in the Boer War where Aussie-kidnapped Boer women and children (who'd been ethnically cleansed from South Africa) were held in squalor and misery. Some 27,000 died from malnutrition and disease while the mothers, wives and children of the Aussie troops lived in peace.
Aussie troops committed genocide when Britain's Lord Kitchener ordered them to.
In the Australian War Memorial's Colonial Wars section (that I took the Chinese uni student who is staying with us to see the Boxer Rebellion exhibition today) is a letter about the Boer War written by an Aussie Officer in which he called what they did to Boer women and children as a "Beastly Business".
Sadly Aussies are still in the Beastly Business of kidnapping and mistreating women and children in Aussie concentration camps when Lord Rudd or Abbott order it.
