Alexandra Henderson, from Dalyup, was found unconscious on Monday morning and rushed by ambulance to Esperance Hospital in WA';s south where she died from her injuries.

She was working at the farm at Dalyup herding the large bull when she was hit into a fence in a paddock.

The family said they were devastated by the sudden loss of their beautiful daughter Alexandra.

"We are consoled by the fact that she is in a happy place at this time of her life," the family said in a statement.

Alexandra was working on a property she loved, with people she cared for and respected and who felt the same about her, they said.

While Alexandra was only young she had worked with animals her whole life, including cattle and was a competent horsewoman, breaking and training horses, they added.

"She was also a compassionate person who cared deeply about her world and the living things she shared it with," the family said.

"We are happy by the fact that we have spent so much time with her, and that we live in a community which has supported us with an outpouring of love and support."

The family thanked paramedics and hospital staff for trying to save Alexandra.
