Her son Darren said she was lucky to be alive after being attacked by the male kangaroo - which he estimated as up to 2m tall and weighing 100kg.
"The kangaroo has just jumped up and launched straight at her. He hit her once and she just dropped and rolled. My dog heard her screaming and bolted down and chased him off.
"If it wasn't for the dog she'd probably be dead."
"Her face has been ripped apart, her hand has been mauled, and she's got scratches all over her back and concussion.
"There would be a couple of hundred kangaroos within a hundred metres of the house, and last night she was just walking down the paddock to check on the horses before it was dark," he said.
"A lot of kangaroos have just bolted, but the males don't care, they just stay laying down, they're not scared."
