Career stories
"It was the best choice I've made for my career 12 years ago."

I always knew that I wanted a career that challenges me physically and mentally, something that does not bind me to a desk. Plus the love I have had for uniforms, I was completely drawn to the RSAF after having a chat with my career advisor. And it was the best choice I have made for my career 12 years ago.
The RSAF empowers me and has encouraged me to try out different roles within the ADSS vocation, things that I would never get the opportunities to otherwise. Some of them might be challenging, but I know I will always have support, every step of the way.
