A cattle saleyard of the town in North Queensland bought the 440 kg deformed cow at USD 400 on Tuesday, media reports said.
It has a normal head just like any other cow, but on top is another face, which has one eye, a single tooth and two working nostrils.
Saleyard posted pictures of the animal on its Facebook page describing him as in great condition, ABC news said.
Yard chair Gerry Collins said in his 50 years in the industry he had seen extra legs and tails, but never an extra face.
