Looking for a new, digital camera? Advise?

For my birthday I have asked my parents for a new camera but don't know which one. I'm looking for a professional digital camera which is good for beginners (I want to start photography for a hobby). I have been looking at websites such as nikon and canon but I don't know where to start.

I will also be going to a camera store soon but I wouldn't mind some suggestions or hints.

Thank you!

Added (1). Hi, sorry for the lack of details I was in a rush,

1 I would like a price under $600 AUS
2 Size doesn't matter
3 I would like to learn to use shutter speeds/apertures
4 Don't particularly mind

First lets clear something up. There are no "professional" cameras for beginners - they don't exist.
Professional cameras in the Canon line for example begin at about $3, 500 and go up from there.
slr cameras begin at $500 and go up from there.

Here's a good place to do research.

Next time you ask this question or add more in additional comments ask for help in a way where someone can sorta pinpoint what you're after.
1 How much ya spending
2 Do you want a tiny camera or size doesn't matter
3 Do you want a very simple camera or one where you can learn to use shutter speeds/apertures
4 Do you want lots of zoom or doesn't matter
