Proportional Representation Society of Australia

[1] The Society regularly reviews and makes submissions on electoral reform within Australia with a focus on implementing proportional representation through the single transferable vote.

Catherine Helen Spence's 1861 booklet,[2] A Plea for Pure Democracy, and her other writings and activism encouraged the 1895 formation of a proportional representation group called the 'Effective Voting League of South Australia'.

A statue in Light Square in Adelaide, unveiled on 10 March 1986 by Queen Elizabeth II, commemorates Miss Spence.

In some places, even outside Australia, PR-STV (and its single-winner version, instant-runoff voting) was referred to as Hare-Spence in honour of her work.

PRSA Inc. also provides services in counting votes or fully conducting elections[12] for corporate and community organizations in Australia including economical computations of results by email.
