Claire Austin's final act was running for her life. She never made it to safety.

Claire Austin ran for her life. She was so determined to live that she ran through a glass door in a desperate attempt to flee an alleged domestic violence incident.

She. Ran. Through. A. Glass. Door.

What was on the other side of the glass door was better than whatever she was facing. The desperation is beyond devastating.

It left the 38-year-old with such catastrophic injuries she spent three days fighting for life in hospital before her death on Tuesday.

It's left us asking the same question we hear time and time again: When will enough be enough?

Claire was a "beautiful human in every sense of the word". She was someone who uplifted others. Someone who people naturally gravitated towards. Someone who many felt lucky to call a friend.

The loss is devastating.

Police were called to Claire's unit in Randwick on Saturday morning after a neighbour reported hearing an argument.

When they arrived, they were met with a confronting scene. Claire had suffered a severely lacerated arm.

The Sydney Morning Herald reports Claire cut an artery in her arm when she tried to force her way through a sliding door in her top-floor unit to escape an alleged domestic violence incident.

Paramedics rushed her to St Vincent's Hospital in a critical condition.

Following the incident at Randwick, police applied for an apprehended violence order on behalf of Austin, The Herald reports.

The application was due to be heard in Waverley Local Court on Wednesday.

Claire never made it.

The marketing executive, who was born in the UK but has lived in Australia for 10 years, had spent three days on life support before she died on Tuesday.

A 44-year-old man known to Claire was arrested at the scene, police said.

He was taken to Maroubra Police Station for questioning and was later released without charge. No arrests have been made at this time.

NSW Premier Chris Minns described the tragedy as "disturbing".

"I feel so terribly sorry for that woman and her family," he said. "I can just imagine how devastated they are today. It's another example of somebody dying, allegedly at the hands of domestic violence.

"I want the public to be assured that there's a task force that's been set up by NSW Police. They're taking it incredibly seriously and the focus will be justice for that woman and her family."

NSW Police Minister Yasmin Catley also expressed her condolences.

"Here we see another death at an alleged domestic violence incident, another one too many," she said. "We've seen too many of these, as we know."

Claire's employer Misfits Media Company confirmed the tragic news, saying it was mourning one of its own.

Her previous employer from The Do Collective, Ben Walker paid tribute to Claire remembering her as a "beautiful human in every sense of the word".

"With kindness in her heart and a generous spirit, she had a warmth that we all gravitated to," Walker told Misfits Media Company's B&T. Her compassion for others was evident in the way she worked and lived.

"To those who knew her, Claire wasn't just a colleague at The Do Collective, she was a friend. Her presence uplifted the team and her endless determination made a lasting impact on every client she touched.

"She will be deeply missed, but her legacy of kindness and warmth will live on in all of us who had the privilege of knowing her."
