A woman suffered multiple injuries after using her body as a shield to protect her 4-month-old daughter from a hailstorm.

Fiona Simpson, 23, was driving to her home in Kingaroy, Australia with her daughter and her 78-year-old grandmother when the hailstorm hit.

Some hailstones were the size of a tennis ball. Upon impacting the car, the rear window was shattered. Fiona stopped the car, jumped into the back seat and acted as a protective shield for the child.

"It was scary, but I had no time to be scared. It all happened very quickly,"

Once the storm passed, Mrs Simpson drove her badly damaged car to a nearby house and called for help while waiting for an ambulance.

Ms Simpson said once paramedics arrived she went into shock and her whole body felt "numb".

Despite the terrible ordeal, her mother said she wouldn't hesitate to do the same thing again.
