Protesters will gather at US embassies and consulates around the world to protest the extradition of WikiLeaks co-founder Julian Assange.
Australian-born Assange was arrested on Thursday after Ecuador withdrew his asylum and he is now in British custody.
He is facing an extradition request from the United States on charges of conspiring to break into a Pentagon computer system.
Protesters in Melbourne will gather at the US consulate on St Kilda Road on Sunday.
Activists are also expected to gather at consular offices and embassies in Sydney, Auckland, Wellington, Dublin and Toronto.
