The mother of a "beloved" young man who fatally overdosed at a New South Wales music festival pleaded with politicians to step aside and let the experts determine the policies so that his son and the others who died could to be "the faces of change".
Julie Tam, mother of Joshua Tam, 22, told an inquiry into the death of her son and five other young people at New South Wales music festivals between December 2017 and January 2019 should not be in vain.
Alexandra Ross-King, Diana Nguyen, Joseph Pham, Callum Brosnan and Nathan Tran, aged between 18 and 23, also died after ingesting illicit drugs when it was hot.
Deaths were examined by State Deputy Coroner Harriet Grahame at an investigation that ended today.
"The faces of our children must be the faces of change," said Ms. Tam, describing herself and the other parents as "the massacre left behind."
"We may not be able to bring Josh back to us as we would with any fabric of our being," he said to the question.
"I think I can speak for all six of us parents when I say that I wish a reckless moment of abandonment did not lead to these tragic results, but that you were destined to create an undulation so far and so wide that this changing landscape does not can and should not be ignored. "
While the investigation ended at the court of the Lidcombe coroner, Ms. Tam stated that it was "terrifying to think that summer is coming" and with it "the next assault of festivals".
Grahame will release his findings on November 8th, so his advice will be published before the apex of the summer festival period.
Ms. Tam said in the investigation that no "magic bullet" would save other families from feeling the pain of losing a loved one that way.
However, he suggested having more emergency health professionals in place than not holding festivals when temperatures rose to dangerous levels and departed from the police.
He also called for drug control, saying "he may not have saved Josh … it may have been the missing factor".
"He could have saved another one, that's all it should matter," he said.
"Those who stand in the way of change stand aside … I do not believe that political parties should be involved in decisions like these. Re-election should not influence important reforms."
Ms. Tam was one of a series of parents who made statements of inquiry in her last moments.
Alexandra Ross-King's mother, Callum Brosnan's parents and Joseph Pham's mother also shared their pain.
Jennie Ross-King told the inquiry about the final conversation she shared with her daughter Alex, 19, whose final words for her were "I love you too, mom."
A few hours later, she received a call from a friend of her daughter and while she was going to the hospital, a doctor told her on the phone that her son had gone into cardiac arrest.
Later that day, the doctors told her there was nothing else for her daughter to do.
"I spent an hour and a half later with Alex, watching her sleep as I had on so many occasions," Ross-King said in tears.
"It was the last memory I have of her. Please don't let another parent remember it. "
Lucy Pham, mother of Joseph, 23 years old, said in the investigation how much her family missed her hungry son and how generous he had been to those of his life.
Heidi and Cornelius Brosnan shared a piece of music that their talented son, Callum, 19, had composed in his brief spell on earth and described his parents as a "privilege".
