Dunn has won twice as much prizemoney as any other bull rider in this season's Australian Professional Rodeo Association circuit, but will face tough opposition on the Easter weekend.
He will face a field including standings runner-up Sam Champ, of Meldale, near Caboolture, and the Mara brothers.
Originally from Cloncurry in western Queensland, Troy and Jason Mara have also lived in the central Queensland area and have been two of the top riders in the APRA for the past decade.
Former Western Australian rider Gerard Oversby will compete in the bull ride and bareback bronc ride after placing in bareback at this year's Warwick Rodeo.
Wyreema cowboy Ben Palmer is one of the bull riders on the way up and is a likely prizemoney winner in the bull ride at the Easter rodeos. Wagga Wagga rider Sean Lynch will make the trip from southern NSW contest all three bull rides in Queensland over the Easter weekend.
In timed events, Moree, NSW, cowgirl Wendy Caban is the most successful competitor in the past seven seasons in the APRA. Caban will travel to Queensland for the three Easter rodeos. She is a title winner at all-round level, as well as in the barrel race and breakaway roping, and is equal favourite for any event she contests.
The Easter action in Queensland will start with a Friday bull ride at Roma.
All eight championship events will be held at the Emerald M Group Sunflower Festival Rodeo on Easter Saturday and the Roma Rodeo on Easter Sunday.
Riders are going into the last month of the APRA season with some needing prizemoney to qualify for the Warwick Rodeo Australian Championships on October 22-25 when the top-15 in each event will compete for the titles.
