A New South Wales mother has pleaded for a second chance for an exemption to cross the NSW-Queensland border after her 18-month son has fallen fatally ill. 

The mother was referred to Queensland Children's Hospital for a paediatric endoscopy but denied by Queensland Health Authorities.

The mother was also fully vaccinated, arguing, "It's an eight hour drive to Newcastle, while Brisbane is only two hours away, it just makes sense to go to Brisbane”.
