Socialist Alternative (Australia)

Socialist Alternative (SA, SAlt, or SocAlt) is a socialist political organisation in Australia. Its members have organised numerous campaigns and protests around economic justice, LGBT rights, climate change, racism and refugee rights. The organisation also intervenes in the trade union and student union movements. It has branches and student clubs in most major Australian cities and publishes the fortnightly newspaper Red Flag. Members of Socialist Alternative are sometimes referred to as Trotskyists.

Socialist Alternative organises the annual Marxism Conference in Melbourne, a public event featuring discussions on radical history, revolutionary theory, and anti-capitalist politics.

In 2018, Socialist Alternative helped to establish the Victorian Socialists, an electoral project to win federal, state, and local council positions for socialist candidates in the state of Victoria.
