Health chiefs have launched an investigation into the hospital at the centre of negligence accusations after the Daily Mail revealed an elderly couple died within two days of being denied medical treatment. 

Margaret Wing, 64, and Steven Jackson, 76, died of Influenza A on November 16 after a worker at Inverell Hospital, in northern NSW, allegedly told them there were no available doctors.

The couple had fallen ill and, as their health deteriorated, Ms Wing called the hospital on Friday, November 14 seeking help. 

She was allegedly told they could not be seen until after the weekend.

Tragically, they were both then found unresponsive at their home on Sunday evening.

The couple's daughter, Mandy Wing, blames the hospital for their deaths, but her initial complaint went unanswered. 

Now Daily Mail can reveal that the circumstances surrounding her parents' death are being reviewed by officials in the wake of the tragedy and the Daily Mail's coverage.

But Ms Wing says that while she is glad action is being taken, nothing will make up for her loss.

Ms Wing claimed she made multiple complaints but has yet to hear from the hospital

'They said they are putting policies in place,' she said. 'Great for the future but unfortunately not for my parents.' 

Ms Wing maintains she believes her parents' deaths were preventable. 

'If my mum or dad got to see a doctor, one of them, or maybe both of them, would still be alive.'

Ms Wing added that 'we live in Australia and this sort of thing just shouldn't happen'.

The young mother said her parents initially became unwell with what seemed like a small sniffle, but after being unable to secure a doctor's appointment in town, their symptoms rapidly worsened.

'It turned into the flu and they were really unwell,' she said. 

'I have never seen my dad so weak like that, so they decided to pack a bag and mum called the hospital.

'She asked if she could see a doctor and when one would be available, and she was told she would have to wait until Monday because there was no doctor available.'

Ms Wing said both she and her mother (pictured with a grandchild) had called the hospital 

Concerned there had been a misunderstanding, Ms Wing said she rang the hospital herself.

'I spoke to the nurse who answered the phone with "hello, emergency", and I stressed how sick they were. Mum was wobbly on her feet and I knew they needed medical help.
