Henrietta Augusta Dugdale was a pioneer Australian who initiated the first women's suffrage society in Australia. Non-conformist, provocative and quick-witted, her campaigning resulted in breakthroughs for women's rights in Australia.

Women's suffrage in Australia was one of the early achievements of Australian democracy. Following the progressive establishment of male suffrage in the Australian colonies from the 1840s to the 1890s, an organised push for women's enfranchisement gathered momentum from the 1880s, and began to be legislated from the 1890s, decades in advance of Europe and North America. South Australian women achieved the right to vote in 1894, and to stand for office in 1895 following the world first Constitutional Amendment Act 1894. This preceded even male suffrage in Tasmania. Western Australia granted women the right to vote from 1899, although with some racial restrictions. In 1902, the newly established Australian Parliament passed the Commonwealth Franchise Act 1902, which set a uniform law enabling women to vote at federal elections and to stand for the federal parliament. By 1908, the remaining Australian states had legislated for women's suffrage for state elections. Grace Benny was elected as the first councillor in 1919, Edith Cowan the first state Parliamentarian in 1921, Dorothy Tangney the first Senator and Enid Lyons the first Member of the House of Representatives in 1943.
