"He gouged out the back of my leg, I know now if I hadn't turned around, I would probably have been disembowelled."
Dina said the kangaroo then jumped and pounded on her. She said she lay on the ground playing dead until the attack ended.
"I thought, 'This is happening. Just wait until it's over'," Dina said.
She needed surgery for wounds on her leg and 25 stitches on her face.
She said she didn't blame the kangaroo for attacking her.
"I could sense his panic, I really felt for him the poor thing," she said.
Wildlife experts say the best thing to do is try to calmly back away from aggressive kangaroos, which are capable of disembowelling humans and other animals.
Dina is expected to make a full recovery from her injuries.
