The family of Aishwarya Aswath have commemorated her life as a West Australian coroner prepares to examine what led to the girl's death.
Sunday marked one year since seven-year-old Aishwarya died of sepsis after presenting to the Perth Children's Hospital emergency department.
Her parents, siblings and other loved ones and community members gathered at the family's Perth home to mark the anniversary.
Aishwarya was taken to PCH on Easter Saturday last year with a fever and triaged by a nurse - who did not check her vital signs - in the second-least urgent category.
Within 20 minutes of arriving, her hands were cold, her eyes were discoloured and her respiratory rate and heart rate were significantly elevated.
But a review by the Child and Adolescent Health Service found the severity of her condition wasn't recognised until an hour and 17 minutes later, despite Aishwarya's parents having raised concerns on five separate occasions.
She was pronounced dead within two hours of entering a resuscitation bay, having succumbed to an infection related to group A streptococcus.
An inquest into her death will begin on August 24 and continue for eight days, the WA coroner's court confirmed this week.
Family advocate Suresh Rajan on Sunday read a statement on behalf of Aishwarya's grieving parents, Aswath Chavittupara and Prasitha Sasidharan.
"Aishwarya's tragic death must not be in vain," they said.
"The last one year has been the darkest and most torturous days of our lives. Because of the loss of our daughter, we will suffer for the rest of our lives.
"We want justice. We're relieved that the inquest dates are now set and we're looking forward to finding some answers as to what happened that night."
An independent report last year found staff at PCH had been "exhausted and demoralised" in the lead-up to Aishwarya's death.
The Australian Commission on Safety and Quality in Health Care described the emergency department's triage and waiting areas as vulnerable and "suboptimally staffed", a finding the McGowan government sought to downplay.
Aishwarya's parents said the health system needed to change.
"The key element here is integrity," they said.
"A denial and defensive approach will only make it worse and the suffering of innocent people will continue."
