Assisted by motorcar, the New Guard developed a strategy where they would regularly disrupt left-wing workers' meetings and New guard members spent much of the summer of 1932 driving around doing so. During December 1931, Captain Francis de Groot organised around 1,000 New Guardsmen to attack leftist meetings. On 11 December 1931, three policemen were injured in a fight between New Guardsmen and communists in Darlinghurst. On 13 February 1932, 700 New Guardsmen practised military drills in Belmore and a number of journalists who attempted to document the drills were assaulted. A few days later, 13 members of the New Guard were arrested after violently disrupting a political meeting in Coffs Harbour. Violent attacks on leftist meetings continued for weeks as part of a 'general mobilisation'.
