Racism can take many forms, such as jokes or comments that cause offence or hurt, sometimes unintentionally; name-calling or verbal abuse; harassment or intimidation, or commentary in the media or online that inflames hostility towards certain groups.
At its most serious, racism can result in acts of physical abuse and violence.
Racism can directly or indirectly exclude people from accessing services or participating in employment, education, sport and social activities.
It can also occur at a systemic or institutional level through policies, conditions or practices that disadvantage certain groups.
It often manifests through unconscious bias or prejudice.
