Organised by the Hunter Thoroughbreds Association, the championships were scheduled for this weekend at the Broomfield ground outside Gundy.

In a statement, Equestrian Australia named the girl as Olivia Inglis.

The organisation said she was riding the family horse in the event’s competition about 9:20am when the accident happened.

Ms Inglis was treated by staff on the course and medical crew from the Westpac rescue helicopter.

“The Scone Horse Trials committee and Equestrian Australia offer their heartfelt condolences to Charlotte and Arthur Inglis and their family for their tragic loss,” the statement reads.

“They request their privacy be respected at this time.”

The Inglis family are well known in the world of horse racing and breeding, operating the leading bloodstock company which carries their name.

Equestrian Australia said counselling services had been arranged for event attendees.

Eventing is a discipline which involves dressage, cross country and show jumping.
