Supporters of the Black Lives Matter movement in the Peel region turned out to the Mandurah Foreshore to peaceful protest on Saturday.
Police were on standby as more than 60 people, including children and parents, gathered to stand in solidarity with those of colour.
Protests were also held in Albany and Bunbury, meanwhile, millions of supporters flocked to cities across Australia.
The rallies come in response to Black Lives Matter protests in the US after a white police officer allegedly killed unarmed black man George Floyd by kneeling on his neck during an arrest last month.
Mandurah’s demonstration organiser Amanda Broad said the group was protesting over the inequality and mistreatment of Indigenous Australians.
“We’re protesting against injustice for not just Indigenous people but for people of colour,” she said.
“Mandurah’s a big place for people of colour and I think its really important to try and get everyone out here.
“Just because we’ve got different colour skin doesn’t mean we are not the same.
“I don’t think it’s just for the US, over there, it’s for all the indigenous down here as well.”
Ms Broad said she was concerned about what was going on with law enforcement officers in the United Stated.
“I think it’s absolutely disgusting, I seen this morning that a disabled man in America was shot with rubber bullets and he did nothing wrong,” she said.
“I think police are using to much force for people of colour, they don’t use that much force with us, white fellas.
“Everyone needs to start treating people with colour with the same respect that us white people get.”
Vision of George Floyd’s violent arrest was posted online and has since sparked outrage across the world.
As the movement gains momentum, hundreds of videos have surfaced of police brutality and racial profiling by officers in the US.
The officers involved in Mr Floyd’s death have all been charged but that isn’t enough to stop the people of America, they demand equality.
