The Democratic Socialist Perspective was an Australian Marxistpolitical group, which operated as the largest component of a broad-left socialist formation, the Socialist Alliance. In 2010, the DSP voted to merge into the Socialist Alliance.
In 2001, the DSP, along with several other socialist parties including the International Socialist Organisation, formed the Socialist Alliance, initially an electoral vehicle. In 2002 the DSP championed the idea of turning Socialist Alliance into more of a party formation, although at first it had to withdraw this proposal as the ISO's opposition threatened to destroy the alliance. In 2003 the DSP became the first Socialist Alliance affiliate to become an internal tendency within the Alliance, changing its name to the Democratic Socialist Perspective, in line with its view that SA should become a "Multi-Tendency Socialist Party", a view that the May 2003 National Conference of the Socialist Alliance subsequently adopted. Each of these changes of name and tactics has been accompanied, like in many far-left groups, with a turnover of members. While the SWP and DSP recruited many activists from the radical student movement of the 1970s and from various social movements since, it failed to retain most of them for long as the sixties and seventies radicalisation wave has receded. Nonetheless, the DSP has retained a core membership drawn from each upsurge of political struggle, some of whom are founding members of the party back in 1972. The SWP, and then DSP, was led by Jim Percy as National Secretary from 1972 until his death in 1992. The Socialist Alliance had been created in alliance with other forces in the hopes of using joint electoral work amongst Australian socialists to increase trust and collaboration between socialists, and in the process making socialist organisation a more attractive option to the left. But although it contested the 2001 federal election and the 2004 federal election, as well as several state elections, it has failed to attract significant support. The Socialist Alliance has had two electoral successes, electing Sam Wainwright to Fremantle City Council in 2009 and Sue Bolton to Moreland City Council in 2012. A debate broke out in the DSP in 2005 about its Socialist Alliance orientation but the minority viewpoint that opposed continuing with the Alliance orientation was soundly defeated at the DSP's January 2008 congress. This caused a split, after the opposition was expelled subsequently forming a new organisation the same year, the Revolutionary Socialist Party. In October 2009, the DSP National Committee proposed that the organisation merge itself into the Socialist Alliance. At the DSP National Congress in January 2010, the membership voted to go ahead with the merger.
