Canberra’s tightly knit Fijian community is in mourning after a Boxing Day road tragedy robbed a Chisholm family of their grandparents and left a 14-year-old boy in hospital.

Just before 7am on Boxing Day, a Nissan Patrol 4WD carrying seven members of the family  left the Hume Highway north of Holbrook and rolled.

The grandparents, both aged 70, died at the scene.

They were Fijian citizens who had flown to Australia to spend Christmas with their family,

Their 14-year-old grandson was airlifted to Canberra Hospital where he was in a critical condition with head injuries. Another relative was flown to the Royal Melbourne Hospital with spinal injuries.

The woman, 67, was  in a serious but stable condition on Wednesday  night.

The driver of the car, a 44-year-old-man, was believed to be the son of the dead couple and father of the critically injured boy.

He escaped with minor injuries along with his wife, 45, and sister-in-law, 40, who were all taken to Albury Base Hospital where they were treated for shock.

The family, who were well known to many members of Canberra’s Fijian community, were believed to be travelling to Melbourne.

 Members of the community said on Wednesday that they were shocked by the tragedy.

Police still do not know why the vehicle left the road. Holbrook is about a three-hour drive from Canberra.

Inspector Tony Moodie, from Albury Police, said the ‘‘tragic accident’’, served as a reminder for drivers to be alert.

Three other people were killed on NSW   roads on Boxing Day, taking the national holiday road toll to 16.

The Ambulance Service of NSW described it as a ‘‘horror day on the road’’ and urged drivers to slow down.
