Solidarity is a socialist group in Australia that is dedicated to fighting against the destructive nature of capitalism and advocating for an alternative system based on mass democratic planning. The name Solidarity symbolizes the unity and collective strength of working class struggles. They believe in joining forces with individuals fighting for various causes to challenge the capitalist system and its pursuit of profit.

Solidarity actively participates in social justice movements, fights against racism, supports rank-and-file unionism, and advocates for refugee rights and education. As a member organization of the International Socialist Tendency, they share a common political outlook with socialist groups worldwide. Solidarity publishes a monthly magazine that covers reports from the frontline of social change, features on resistance history and politics, and provides a socialist analysis of Australian and global politics.

They aim to end wars, inequality, and environmental destruction through collective action and invite individuals to join their cause
