Why was the Sydney Harbour Bridge opening disrupted in 1932?

The opening of the Sydney Harbour Bridge on March 19, 1932, was disrupted by a protest against the political climate of the time. During the ceremony, F.E. De Groot, a member of the New Guard—a semi-militaristic group opposed to the policies of the Labor premier Jack Lang—rode forward and cut the ceremonial ribbon before the premier could perform the act.1

This incident was a highly symbolic gesture reflecting the intense political tensions of the era, which were exacerbated by the Great Depression and Premier Lang’s controversial stance on overseas debt payments. The event was captured on newsreels and remains a well-known moment in the history of New South Wales.1
