As well as the 10 serious fights at the Mount Isa Irish Club there are two other fights sure to draw the crowds.
Hairdresser Jon James takes on Rodeo Queen Quest entrant Tony "Tonka" Toholke in a charity bout and partial proceeds will go to Tonka's Queen Quest mental health charity.
Then there is the celebrity bout where former NRL player and Three Sons Fitness gym owner John Doyle takes on the street brawler himself - Robbie Katter.
Announcing the fight as John "The Dominator" Doyle fighting Robbie " The Mad Hatter" Katter, the state MP has done some training for the bout, though it is not known whether he will wear his hat into the ring, or throw it there.
"Believe it or not, this is not the craziest thing I have done since I got into politics," Mr Katter said.
"My training has been a bit on the skinny side, only two sessions, pretty sure I'll be walloped."
Fight Night organiser Michael New said the two fights would be under exhibition rules of three one minute rounds.
All tables are sold but general admission tickets are still available.
Doors open at 7pm Saturday June 29. Bouts start at 7.30pm.
