The 63-year-old Moree woman was a passenger in a prime mover when it rolled at the intersection of Irrigation Way and Whitton-Darlington Point Road on Tuesday last week.

While the 53-year-old man who was behind the wheel of the truck at the time escaped the crash, the woman was taken to Canberra Hospital by air.

She remained in a critical condition, placed in an induced coma, and died in the hospital just before 1.30pm on Anzac Day.

The driver of the truck has undergone mandatory testing, and Murrumbidgee Police District officers are investigating just what led to the fatal crash.

Anyone with information in relation to this incident is urged to contact Crime Stoppers by calling 1800 333 000 or via the online reporting page. 

A report will be prepared for the coroner.
