Fifty-nine-year-old Janet Till was taken to Fitzroy Crossing Hospital last Wednesday morning with a fever. She was discharged later that afternoon. By Thursday morning, she had died.

It started as a typical weekday morning for Ms Till in her Kurnangki home — a small community about five kilometres outside the town of Fitzroy Crossing, in WA's Kimberley region

The Gooniyandi and Walmajarri woman had been playing with her niece Rose Shaw's children that morning.

Ms Shaw, 34, said a NDIS support worker noticed Ms Till wasn't feeling well at around 10.30am.

Ms Till told her niece, "I'm not feeling good", and was shivering under a blanket.

She had suffered a stroke a couple of years ago, which left her paralysed on the right side and in a wheelchair. Her medical needs meant she had been a frequent visitor to Fitzroy Crossing Hospital.

At 11am, Ms Shaw called an ambulance, which took her aunt to the hospital for treatment.

Ms Shaw said she was stunned when paramedics drove her aunt back to the Kurnangki home at about 4pm that afternoon.

"I thought they was going to keep her, because of how she was shivering," she said.

Instead, paramedics gave Ms Shaw antibiotics to give to her aunt but offered no diagnosis or explanation for the medication.

"They never told me what fever she had, or what was going on," Ms Shaw said.

"They gave me some antibiotics. They said that she needed to take the antibiotics.

"They had one for evening and one for morning. It's just half a tablet."

That evening Ms Till ate dinner with her family and spent time with Ms Shaw's children.

Her maternal instincts were widely known in Kurnangki, with Ms Shaw saying she "raised lots of children".

Ms Till went to bed after being given her evening dose of antibiotics.

Around 6am the next morning, Ms Shaw was outside the kitchen, as her cousin Christine was cooking breakfast.

When family members went to wake Ms Till, she was unresponsive.

"She was cold," Ms Shaw said.

She immediately called an ambulance. Paramedics told her to perform CPR, but it was too late.

In the wake of the tragedy, Ms Shaw is questioning the medical care her aunt received at Fitzroy Crossing Hospital.

"They should have done their job properly," she said.

She said Ms Till had been kept in hospital longer on previous visits when unwell.

A WA Country Health Service (WACHS) spokesperson, which oversees Fitzroy Crossing Hospital, offered condolences but did not outline what medical treatment Ms Till received prior to her death.

"The loss of a local community member is felt deeply, and we extend our sincere condolences to family and loved ones at this difficult time," the spokesperson told National Indigenous Times.

The agency said it is launching a review into Ms Till's death, which occurred in under 24 hours after her discharge from Fitzroy Crossing hospital.

"To gain a detailed understanding of the circumstances, WA Country Health Service has commenced a clinical review of the care provided to the patient, who sadly passed away. While this process is undertaken, and out of respect to the family, it is inappropriate to comment further at this time," they said.

WA Minister for Health Meredith Hammat expressed condolences for the loss.

"My thoughts are with family, friends and the wider community as they grieve their sudden and tragic loss," Ms Hammat said.

"I'm advised a clinical review is already underway, so we can ensure family receives the answers they need as soon as possible."

Minister for the Kimberley Stephen Dawson said his "sincere condolences go out to family and friends along with the Fitzroy Crossing community".

"I have been advised from the WA Country Health Service that a clinical review is underway to assist the family in receiving answers on what took place," Mr Dawson said.

Reflecting on her aunt's life, Ms Shaw struggled to capture the full scope of her impact on the community.

"She was everything," she said.
