He has spent 60 years at the Outram Rodeo taming bulls and horses trained to buck riders off their backs.
He looks after the animals before and after they enter the arena and makes sure they are handled the right way.
"When I first started I was doing the same job as I’m doing now, except I wasn’t the boss," Mr Nichol said.
"I haven’t done it completely wrong yet, so I don’t know what happens when you do it wrong."
The secret to controlling the animals was staying calm and showing authority, he said.
"I read them all the time, I know the little things they will do if things aren’t going right."
Mr Nichol said the bulls were playing the game just as much as the riders at the rodeo.
He noticed some bulls would change their techniques when they were not able to buck a rider.
The culture at the rodeo had changed and it had become a lot more family-oriented and more precautions were taken to look after the animals now, Mr Nichol said.
Thousands of people attended the rodeo yesterday and Outram Rodeo Club president James Adam said it was one of the biggest in recent history.
There were more than 350 contestants taking part in eight different events including rope and tie, steer wrestling and the bull ride.
Mr Adam said the contestants loved the thrill of riding a tough animal and the crowd loved to see the spills because more often than not it was the horse or the bull that won.
The bulls at the rodeo were D&J Bucking Bulls and Mr Adam guaranteed they would be more than a handful for riders to last eight seconds on.
Savannah Halley, of Warwick, Queensland, said the rodeo was a great opportunity for young people to represent their country and potentially have careers in the sport.
She planned to compete in the United States and run a business for training and breaking horses.
