VAD is a process where a person receives assistance from a health practitioner to end their life.
Ms Doyle first received a cancer diagnosis in 2009, with the condition returning in 2017. At that point, according to Mr Fitzpatrick, it had spread to her lungs and to her bones, rendering her with a terminal diagnosis.
When VAD became available in NSW in November 2023, Ms Doyle applied to receive it, eventually becoming successful.
On May 29, surrounded by her family at her home in Fassifern, Ms Doyle passed.
"She certainly didn't want to go to hospital. She didn't want to be in a home. She wanted to die at home, in her own way, at her own time," Mr Fitzpatrick said.
