Rebel made her international debut in 2003 in the Australian Team at the Trans Tasman Cup in New Zealand. The following year, the pair were members of the Australian Olympic Eventing team at the Athens Olympic Games on Oaklea Groover.

She saved her horse, Oaklea Groover, from the knackery back in 1999. At that time, Oaklea Groover was a race horse but after suffering blood clots in the empty cavity in his skull, the animal was all set to be put down.

“The owners just rang me up and said we’re going to dog him because he’s not worth anything to us if he can’t race,” Morrow said. “They were at the vets and they rang me and said we’ll just drop him off at the knackery on the way home or you can have him for the price we can get for him there which was $300.”

She said right from the first time she hopped aboard Groover and tried to make him jump a fence, she knew she had something special in her possession. “When I hopped on him then in his natural state without feed and fitness, he was just amazing,” she said. “He’s got a real laid back attitude, an unreal canter.”

In 2004 Rebel was awarded the Anna Savage Award, given to the event rider deemed Best and Fairest during the year.
