The family of an asthma sufferer who died during a rare weather phenomenon in Melbourne are shocked at what happened.
Twenty-year-old law student and life-long asthma sufferer Hope Carnevali was one of three people who died during a mass occurrence of thunderstorm asthma.
She had been waiting more than 30 minutes for an ambulance.
"Knowing if they had got there a little bit earlier that the situation might be different is very hard to deal with," said her aunt Melissa Carnevali.
Eighteen-year-old Omar Moujalled also didn't make it to hospital.
Officials say the weather event put more strain on the health system than a mass casualty terror attack.
Two thousand people experienced breathing difficulties and ambulance Victoria received six times the normal number of calls.
