Good on you, you'll enjoy the experience, meet a lot of good people, and have a ton of fun!
I did about 18 months with C coy here in Gladstone in the late '80's, but got out early due to a car accident and pressure from a girlfriend at the time..
We did our pre-recruit course in the barracks there in Rocky, and for our PT's, we had to run down along the Fitzroy and back.
Unfortunately I wasn't a real good runner (still hopeless), and had to piggyback our Sargeant around the course as punishment a couple of times....
Then we did our recruit course up in Townsville at Lavarack Barracks for two weeks, and did our navigation exercises around the back of Mt. Stuart.
At the time I didn't appreciate the opportunity, but looking back now it was a great time.
The live fire exercises at Shoalwater are something else!
