A large crowd gathered at the Perth Cultural Centre for a Black Lives Matter rally on Saturday afternoon.
The protesters plan to march through the City Mall to Forrest Chase.
The rally follows similar protests in other Australian cities and throughout the United States following a series of shootings there in which white police officers shot black men.
Organisers of the Perth rally said they had organised today's march "in solidarity with the Black Lives Matter movement and denouncing institutionalised racism, discrimination, deaths within our judicial system and racial profiling in our own country".
