She performed well against more fancied senior riders to guide Kitchwa to second place in her first Super Series event two weeks ago in Pukekohe.
That effort now needs to be backed up in pre-Christmas events at Woodhill Sands, Pukete and the Christmas Classic at Taupo, she says.
"It's a calculated risk to enter these events but, if you think you are ready, then you are ready," she said.
Georgia has long been recognised for her natural riding talents.
"It is an adrenalin rush in the ring and I get incredibly nervous beforehand but, when I'm in the ring, it's all go," she said.
Her mother has provided much of the motivation as well as tuition on some of the finer points.
"She has never had a lot of lessons; when she is in the ring I leave her to it," Jeanie Wiltshire said. "She watches other riders and reads all she can on how to improve and just figures it out herself.
"There's no spoon-feeding."
Jeanie Wiltshire says her daughter has taken on the responsibilities needed to be a top equestrienne.
Georgia is schooled by correspondence which allows her to train and maintain three horses five hours a day. She has also worked part-time at a Rotorua cafe to help fund her ambitions.
Expenses such as buying feed, lessons, and entering and travelling to events all require funding - more than $10,000 per horse per year.
"It is a commitment which keeps her feet on the ground, away from becoming a mall-rat and going to parties," said her mother. "We are fully supportive of her but once it becomes a chore and is not enjoyable is when it is time to stop."
Georgia is hoping to spend three months in Europe next year to learn more about showjumping and is open to any funding opportunities to help fulfil her long-term goals.
