Chantelle Doyle, 35, was surfing off Shelly Beach at Port Macquarie, New South Wales, when the attack took place.
Her husband punched the shark until it released its grip and then helped Ms Doyle to the shore.
The area was patrolled by drones, jet-skis and inflatable rescue boats to help spot the shark and assist the NSW Department of Primary Industries on Saturday afternoon.
The shark was sighted by emergency services some time after the attack, but its whereabouts were unknown by Saturday evening.
