Two grey nomads are in hospital after their caravan rolled near Borroloola in the Gulf Country.
Police say seat belts saved the couple, aged in their 60s, from more serious injury but they needed to be flown by CareFlight to Royal Darwin Hospital.
The scene of the accident was attended by medical experts, police and emergency services. No further details about the circumstances surrounding the accident have been released.
In another accident further south, a 63-year-old man was injured after he was struck by a caravan being reversed at Mataranka. He was also flown by CareFlight to Royal Darwin Hospital
