When Mechelle Turvey's 15-year-old son Cassius died following an attack on the way home from school, she could have succumbed to the sense of rage expressed by many at rallies and vigils across the nation.

Instead, she called for calm and unity, determined that her son’s legacy would be a positive one. She has taken a job with the WA police and was named WA of the Year in recognition of her community work.
