Seems this thread has some info for you.
I don't know about other options, but it is always good to work on Work Visa if you have full time permanent position.
For residence, if you have your job on absolute skill shortage list or long term skills shortage list, you can apply. If you have an offer, you need just 100 points.
of course, please do an initial check in points indicator and for details go through opsmanual for your uni and year of pass out to claim the points.
Regards,
Raju
