A man has had surgery after suffering a collapsed lung in an attack by wild deer in the Royal National Park, south of Sydney.
The 57-year-old man told police he saw two large stags harassing his tame deer about 3.15pm on Friday near his Otford home.
The man tried to scare the stags away, but instead they turned on him with one charging him.
Its antler pierced his chest and abdomen.
Ambulance paramedics treated the man at the scene but called in their helicopter to airlift him to St George Hospital.
He is now in a stable condition following surgery.
