Louisa Lawson became actively involved in the burgeoning women's suffrage movement in New South Wales. She recognized the importance of gaining the right to vote as a means of achieving broader social and political reforms.

Louisa Lawson founded The Dawn Club in 1889. It was an organisation for women to discuss political, social and literary ideas. It became a place to push for suffrage.

Louisa Lawson played a key role in establishing the Womanhood Suffrage League of New South Wales, serving as an inaugural member and a prominent figure in the organization. The League advocated for women's enfranchisement through lobbying, public speaking, and petitioning.

Louisa Lawson frequently spoke at public meetings and rallies in support of women's suffrage. She articulated the arguments for equal rights with passion and clarity, challenging prevailing social attitudes and prejudices.

After years of campaigning and lobbying, women in New South Wales finally achieved the right to vote in state elections. This victory was a culmination of the efforts of numerous activists, including Louisa Lawson, and marked a significant milestone in the fight for gender equality.
