The family of an elderly couple who both died after being turned away from their local hospital have accused medical staff of negligence, claiming the pair would still be alive if they had been properly treated.

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 heartbroken daughter, Mandy Wing, is now demanding answers and she has blamed the hospital for their deaths.

'I'm upset and really angry because it could have been prevented,' Ms Wing told the Daily Mail.

'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.'

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.

'The nurse was a bit rude really. Maybe they were understaffed, maybe she was trying her best, but that's no excuse. They have a duty of care and I was just told there was no doctor available.'

Ms Wing said it was not until after her parents died that she was informed they could have received assistance if have presented to the emergency department themselves, or called triple zero.
