Thanks for your reply @Lady Rainicorn , Actually it's mentioned as "Closed" at the ACT occupations list.
wow..I didnt know these. I'm so unlucky,The occupation "Web Developer" which is in the same category as mine was closed too.
Anyway I've noticed "Multimedia Specialist" is listed at the SA nominations list but its only for the Australian Graduates,
I've attached a screenshot here.

Do you have any idea, that they would bring it up to a state nomination list in near future?
Thanks in advance,
Have a great day!
