BITS Saints pair Uma Brennan and Ryan Shanks and Gladstone Mudcrabs' Trey Dummett join 12 other boys and girls in the elite pathway.
Capricornia AFL regional manager Scott Smithwick said the trio deserve the recognition.
"Uma's a little jet and she's got fantastic skills and she's got pace to burn she's proved that she can play against the bigger bodies as well," Smithwick said.
"That's the exciting prospect just because of her pace and her skill and she finished runner-up best and fairest in our local competition and she can certainly play."
Trey has enjoyed a solid season with the Muddies A-grade and has shown great signs as a strong-marking forward.
But Smithwick said the strapping player plays in defence in representative level.
"At a higher level he's more of a defensive player and he plays centre-half-back and full-back," Smithwick said.
"He makes pretty good decisions in congestion which is good for a big fella and he distributes the ball well to the running players."
Smithwick described Ryan as another quality midfielder who never stops running.
"He's got the heart of a lion that kids and he just runs and runs and runs," he said.
"he uses the ball really well and I'm very excited having him in the academy.
"I have been watching him for three or four years and looking forward to making him a bit cleaner on the deck."
The trio will train in Gladstone and Rockhampton ahead of the U18 championships which will be held early next year.
