I came to the same point some 20 years ago and joined the RAAF an Air Traffic Controller as AsA were not recruiting at the time.
I enjoyed every minute of it, however, be prepared for a lack of stability due to regular postings with the RAAF.
Because of the skills, experience and qualifications I gained through the RAAF I am now in a senior management position in a large government organisation.
AsA and the RAAF are both good employers and suit different people at different times of their lives. By the sounds of it AsA may suit your circumstances better.
All the best in whatever you do.
