MacAuley joined the WSPU by 1907, engaging herself as an organiser and planningactivities in multiple locations across England. This entailed living a nomadic lifestyle for a few years. She was the WSPU organiser for Canterbury and South Kent from 1910-1912. During this time she lived in "Trevarra", a boarding house used by WSPU organisers and escaped "mice". In 1913 MacAuley was arrested alongside Annie Kenney in London.
