Anti-racist protesters have gathered in Melbourne's CBD ahead of a rally by anti-immigration activists.
The group of about 100 anti-racist protesters gathered on the steps of Parliament in Spring Street and chanted "racists are not welcome here".
The protesters have gathered ahead of a planned march by an anti-immigration group, which organisers claim will celebrate the Australian flag.
The intersection of Bourke Street and Spring Street has been closed.
Hundreds of police are expected to attend the rallies amid fears of violent clashes.
