Voting is neck and neck in the Colonial First State Sports Boost with Victorian gymnast Madelaine Leydin sitting in second place as she competes to win $10,000.

Maddi was selected to be a part of the program prior to the 2013 Australian Gymnastics Championships where she won her first Senior All Around national title.

"When I was selected to be a part of the Colonial First State Sports Boost my family and friends were thrilled for me. My family is really supportive and they are really happy and proud that I am part of it," said Leydin.

If she was to win the major prize, Gymnastics Australia would also be awarded $15,000.

"It would help with finances such as buying leotards, physio and massage. It would also help Gymnastics Australia who have helped me a lot and supported me throughout my career. It will help them help others, particularly younger athletes," said Leydin.
