Corporal Natasha Wilson grew up in Kyneton, Victoria, and joined the ADF as a combat systems operator with Navy before a career change beckoned.

That change shows the flexibility and cohesion of the ADF, as Corporal Wilson became an Air Force physical training instructor at RAAF Base Tindal in the Northern Territory. 

"This has been the most enjoyable chapter in my 20-year career with the ADF," Corporal Wilson said.

"Physical training instructors have a job to do keeping personnel fit to ensure they are ready and able to perform their roles to get our aircraft airborne."

A member of No. 17 Squadron for the past three years, Corporal Wilson is one of a close-knit and professional team at RAAF Base Tindal, just outside Katherine, 300km south of Darwin.

"The posting to Tindal has allowed me to enjoy a unique lifestyle while being able to apply the scientific approach we take to getting our members to the best fitness level possible and to look after them for longer," Corporal Wilson said.

"Today we constantly monitor and update our programs in line with the latest research and trends from scientific assessment of fitness training.

"It is amazing just how far technology has progressed in our first century and just how much it has changed since the Air Force was formed."
