Air Force Cadet Tegan Thomas has followed up being named 622 Squadron's cadet of the year in 2018 by becoming Murray Bridge's young citizen of the year.
She undertook an international air cadet exchange to Canada in the past year, and also represented South Australia in a national cadets rifle competition.
Locally, she has been involved in teaching and training 15 younger cadets.
She would no doubt be a leader to watch in the future, council chief executive officer Michael Sedgman said.
She thanked the Murray Bridge council for the honour, and her fellow cadets, Air Force Cadets staff, her friends and family for their support.
The three other nominees in the category were Michael Reardon, Aidyn Loveday and Jess Hattam.
