Dylan Dunn claimed the HH Sheikha Fatima bint Mubarak Apprentice Jockeys Championship (IFAHR) in Abu Dhabi overnight, making it back-to-back wins for Racing Victoria apprentices.

Following on from Ben Thompson's success in 2015, Dunn was Australia's representative in the all-apprentice race aboard purebred Arabian horses - and he was able to salute aboard the Jean de Roualle-trained Qader in the mile race that was worth a 150,000 dirhams (AUD$54,120).

Dunn led all the way aboard the four-year-old, who cantered to his maiden win by 7.25 lengths from Ameer Al Reef, ridden by German jockey Ester Weissmeier, while third place went the way of Mauritian hoop Kersley Ramsamy aboard Snaffy.

Dunn, 21, was in the United Arab Emirates along with fellow RV apprentice Jordan Childs for the Sheikh Mansoor Festival, and he paid tribute to the Apprentice Jockey Training Program for improving him in the saddle.

"First of all, I have to thank Racing Victoria. Since I've been back in Victoria, they've really helped me with everything I need. You can really tell by the way my riding's come along in the last 12 months, and that's a great credit to them," Dunn said.

"I have to thank my trainers, not only David, Tom and Ben, but the little stables as well, because in actual fact it's all them that come together and can make me a good or bad jockey.

"It's been a fantastic journey - I've learned things, met people... if it wasn't for Sheikh Mansoor and Lara Sawaya, this event wouldn't be going ahead.

"This event was bigger and better than I thought it would be.

"To have so many countries from around the world come together in one place is something special.

"It's been fantastic that Racing Victoria have been able to have the past two world champions."

Dunn said trainer De Roualle should have a bit more luck with Qader in the future, the horse having been placed once from seven starts prior to his breakthrough win.

"He likes to roll along at a leisurely pace, and he started to pick up at the 600m mark," Dunn added.

"It's not like it was an easing time in front, it was a matter of rating my horse as well as I could.

"Once I asked for the trigger, I felt I might have gone too soon because I couldn't hear them coming behind me.

"I think this horse has got plenty of upside out of this."
