Knickers, the black and white steer, stands out from the herd.
His owner Geoff Pearson said he roamed the paddocks of his feedlot near Lake Preston, about 90 minutes south of Perth, with hundreds of cattle following him.
An enormous steer standing nearly two metres tall and weighing more than a small vehicle eats about 30kg of grass and grain a day to reach his monstrous size.
The 7-year-old Holstein-Friesian is 6 feet 3 inches tall and weighs 3,086 pounds.
Since he is no longer being sent to slaughter, Knickers has found a way to be useful around the farm helping to lead and coach other cattle.
Mr Pearson said: "We have a high turnover of cattle, and he was lucky enough to stay behind".

The world's biggest cow will be saved because its 6-foot-4 frame is too big to fit into a slaughterhouse, a farmer revealed.
He measured about three inches taller than Knickers at a 2010 cattle show in Rome.
While he said it wasn't unusual to a Friesian steer to grow extra-large if castrated young, the hormonal changes could allow the steer's bone growth plates to keep growing if the animal was allowed to live out its life.More news: Hey Siri, OK Google
