What's the difference between radiology and radiography?

Hello there,

I’m considering radiology or radiography as a career, but I don’t understand the difference.

I was wondering if you guys could help me out. The sort of things I’m interested in are:
-what each of those professions involve
-the sort of salary I would receive
-employment opportunities
-the main differences between the two professions
-do they both require university training?
-advantages/disadvantages

Please note that I live in Australia (near Melbourne). I prefer to live in rural areas, so I’m not sure if I would be able to find a good job with one of these professions.

Thanks in advance!
Julia
