When right-wing agitator Francis De Groot upstaged the 1932 opening of the Sydney Harbour Bridge and sliced through the ceremonial ribbon, the antique sword he wielded cemented its place as an Australian national treasure. Part of a monarchist militia called the New Guard, Irish-born De Groot was protesting about a perceived communist push led by working-class hero and nationalist NSW Premier Jack Lang. The ribbon was retied and cut by Lang, but the story didn't end there. A lengthy court battle followed, which resulted in De Groot being found guilty and fined £5 for trespassing. He immediately counter-sued for wrongful arrest and was awarded compensation. The legal battle established that De Groot, not Lang, had legally opened the bridge, which is now included in the National Heritage List. His sword is held by a private collector.
