She was wearing a personal alarm which automatically called triple-0, with call-takers reporting the woman was crying in pain.

Despite the distress call, paramedics didn’t arrive until after 7.30am. Tragically, they were too late.

Triple-0 has confirmed its operator notified Ambulance Victoria instantly after receiving the alert.

Ambulance Victoria says its paramedics were busier than usual overnight, causing delays across the network.

But the organisation has admitted it triaged the case as code three, meaning non-urgent.

Ambulance Victoria CEO Jordan Emery said a review would be conducted.

“Whilst a code three response is not an unusual allocation for patients who experience falls, we really need to undertake that review process and understand if that coding took place correctly,” he said.

The personal alarm company is also under fire after allegations it failed to notify the woman’s emergency contacts.

Neighbour Jill Sheridan said she was on the woman’s emergency contact list but received no notification.

“We’re on the list for if she does fall or anything like that. I don’t know whether I’m first on the list or what, but yes, there was nothing on our phones,” she said.

Police have referred the case to the coroner.
