It was a near miss which drew gasps from the crowd, as Mr Jamison narrowly avoided a head-butt from the half-tonne beast.
The bull fighters might not have the attention of the children, like the clowns, or capture the crowd's imagination, like the riders, but every rodeo rider knows they are the unsung heroes.
Former open bull competitor Chris Nicolson said during his rodeo days, Mr Jamison had his back.
"When you are a bull rider and you have got good bull fighters, it's your peace of mind.''
Mr Jamison (23), who was joined by Henry Pinfold to bull-fight at Outram, said he had done it for nine years.
"When you're out there, your adrenaline's there. The whole time your heart is pounding."
Mr Jamison works safely as an engineer, but during yesterday's proceedings he and Mr Pinfold took their fair share of bumps and bruises. With the adrenaline still pumping though, the pair said, the pain would not kick in until today.
"We normally walk away pretty happy. But tomorrow, after I drive home, the body will be a bit tight."
Outram Rodeo Club president James Adam said between 2000 and 3000 people attended the rodeo and stuck around for all the action despite a brief shower.
A St John spokesman said a woman (40) was taken to hospital with suspected concussion after a fall.
