Your best bet is to just approach places that you would be interested in working at, and tell them you're keen and it nothing is available, follow up every now and again to let them know you're still interested. I did this with a regional airline, and they got back to me, offering me a part-time night shift position cleaning
VB aircraft and loading freight onto Metros. At the moment, I'm really enjoying the job and the environment I'm working in. Great to get close and personal with the aeroplanes and meet people in the industry. I'm currently looking for a full-time job, and will keep this as a second job as I progress through my flight training.
Cheers
