My Dad is a radiographer and they constantly have Sydney Uni students doing their clinical blocks at his work. Although there is not a high demand for radiographers at the moment because of the graduate over-supply, chances are you may get lucky and be employed by them (Dad's work recently hired two of their former students upon graduation). Having said this, it is important to make and leave a positive impression. It isn't only your willingness to learn and cooperation with staff. As you're working with people, it is also important to demonstrate your 'people skills' and also develop a flair for reassuring and calming patients (like any health care professional). It is much like the legal industry, although there is a current over-supply, if you leave a positive impression with your employers/colleagues (especially with your clinical supervisor) get excellent grades, and demonstrate great communication skills, you should be reasonably okay
