Royal Flying Doctor Service spokeswoman Joanne Hill said the 60-year-old woman was attacked Monday at Turquoise Bay, a picturesque tourist spot south of the coastal town of Exmouth.
Hill said the woman would be flown from Exmouth more than 1,200 kilometers (740 miles) to the Western Australia state capital, Perth, for surgery on her right arm.
Hill described her injuries as serious but not life threatening. Hill had no details of the type of shark involved or the circumstances of the attack.
