Apart from the Embassy, as suggested, you can also check with a migration agent.

Prior to the revision of the MODL list (if I'm not wrong), SAP was one of the sought after occupations when it came to IT in Australia. What you've stated is the new list (business analyst, etc).

I reckon that it's still in demand, but from my point of view it seems that getting a job over there is easier for migration. You're company may sponsor you. If you want to apply from here, I believe you can apply as a skilled. As for the process, you can get some info from the AU immigration website or speak to an agent. You could set up a non-committal meeting with an agent to discuss the eligibility (they normally don't divulge details though, since it's their bread & butter) and the general outline of things.

7 years of SAP consulting ought to be enough, as long as the experience is recent. You probably have to get the ACS to verify your experience.

As for your parents, it may take a while for you to get them over. Last I checked, there is a long average waiting time unless you pay the fee.

I can PM you some websites for help if you need, but as suggested by the previous guy, Embassy should be able to answer all your questions. Good luck in your search for details.
