An Australian court probing the death of Stacey Warnecke has heard emergency care was delayed because her "birth keeper" would only call an ambulance if she consented.

In the months before her son, Axel, was born, Stacey Warnecke expressed a deep fear of birth trauma and was adamant she wanted to have her baby on her own terms.

The inquest into the death of a 30-year-old Victorian mum Stacey Warnecke has been told she died from blood loss after she opted for a “free birth”.
