Take aprint of all the 4 forms and attach all the relevant work papers and other copies and attach a DD of AUD 300. Send the papers to NSW office address. It takes about 10-11 weeks for processing and once you nominated by NSW, you will get an invitation by DIAC for visa 190.
I submitted all the forms and documents in November 2012 and m waiting for the outcome. Hopefully i should get the approval by next week.
