A rhinoceros has gored a woman at Mogo Zoo on the NSW South Coast.
A NSW Ambulance spokesman said the woman was being taken to Moruya airport, where she was expected to be airlifted to hospital. It is understood she will be flown to Canberra Hospital.
Paramedics were called about 1pm after reports a 47-year-old woman had been gored by a rhino in the arm.
She was treated for a penetrated wound in her left arm, which was also thought to be fractured.
She was understood to be in a stable condition, and was conscious and alert.
The zoo said both the keeper and the rhino "are OK" and described the incident as “a minor one” which occurred during a "daily routine procedure" with the animal.
"Whilst all safety measures are taken to minimise risk for both animals and keepers, occasionally accidents can occur when dealing with large mega fauna," zoo owner Sally Padey said in a statement.
Mogo Zoo said it would be reviewing its standard operating procedures and an internal investigation was taking place.
Mogo Zoo has two southern white rhinos, which arrived there in early 2015.
Half-brothers Kei and Jabari, both aged 11, weighted about four tonnes each at that point, and were about 1.8 metres tall.
According to the zoo's website, white rhinos are among the heaviest land animals in the world.
"They produce two horns on their snout, made from keratin which can grow up to 1.8 meters in length," the site said.
