Staff Profiles

Kobe Oliver

Owner / Manager

I started gymnastics at the age of 4, competing all the way up to level 7. At the age of 12 I began coaching along side my training. This lead to me to the goal of one day opening a gym. In 2017 I reached that goal and opened Gravity Gym with my business partner Leah. Our aim was to open an all inclusive gym where everyone could develop their skills and love for gymnastics. After only 9 months of being open, Gravity Gym was nominated for ‘Best Medium Gym of the Year’ award which was an outstanding achievement for the gym.

Gemma Still

Gemma started her gymnastics career in kindergym at 2yrs of age, she continued on to be a successful gymnast and acrobat, competing at a National and State level as well as many achievements at Country Championships, Club Championships and many Regional competitions. With approximately 17 years training in Women’s Gymnastics and Acrobatic Gymnastics.
Gemma began teaching pre-levels and recreational classes during her HSC, until the beginning of last year when I started a hair dressing apprenticeship. She has 2 years of full time coaching experience, teaching surfing to ages 4-50yrs. As soon as Gravity Gymnastics opened she jumped at the chance for a career change to something she is so passionate about. Gemma has completed a full time Traineeship at Gravity Gymnastics and has been a fantastic asset to our coaching team. She has now moved into an Assistant Mangers Position.
