I thought it might be helpful to create a resources page for you. I'll add to it as I find things that I think might be useful, and welcome any suggestions. Enjoy!
Seek - http://www.seek.com.au/
Here you can browse jobs advertised, look at company profiles, and set up job mails to notify you when a position that suits you is advertised.
Hays Salary Survey - http://www.hays.com.au/salary/
Not just a salary survey, this will also provide you with market trends in your field, skills in demand, and the forecast for the next 12 months. Probably the most comprehensive salary information available online, it is broken down into position, level and location. Well worth a look.
Linked In - http://www.linkedin.com/
I can't emphasize enough how essential this one is. If you are not on Linked In, you are are missing out accessing probably the widest group of recruiters and hiring managers online. Linked In allows you to upload your resume, highlight key skills achievements, an get online recommendations from people you have worked with. I guarantee you any (good) recruiter who interviews will review your profile on Linked In. If you don't have a profile, but one of the other candidates does, who do you think has the advantage?

The Inside Scoop on your Potential Employer - www.glassdoor.com
This site describes itself as a "free inside look at companies". Reviews are written by current and former employees who comment on things from salary and perks to culture and management style. A great way to answer the question "What are they REALLY like to work for?". Keep in mind disgruntled past employees may use this as an avenue to vent their unhappiness, and try to get a balanced view.
