Congratulations WTBF,
You'll find the experience both the most challenging and potentially the most rewarding of your life. Not only will the ADF provide you with excellent training and a great job with interesting and diverse career prospects, but if you choose to take advantage of opportunites on civvy street afterwards, your military credentials should make you very employable elsewhere.
As an ex-Army chap myself, I look back on my time in the ADF with great satisfaction and I have made some of the best friends I am ever likely to have. Looking back now I realise the thing that made the whole adventure so special was that it was so hard. Adapting to Army life and muddling my way through pilots course was a challenge I am not likely to repeat (and I'm not sure I want to). But shared experiences with others in trying circumstances binds people together like nothing else!
I'm sure you've had (and will continue to recieve) much advice. For what it's worth, work like you've never worked before, take advantage of all the opportunities offered to you and then if you decide to leave, do it before you become jaded by the whole experience - it'll ensure your memories are predominately good ones!
Again, congratulations and good luck with your course. Feel free to PM me if you wish to discuss anything about the course, aircraft types etc.
