Matiko, Unfortunately since 1 July (today) the Marketing Specialist in ACT has turned to CLOSED instead of Limited. Lots of individuals such as my wife, got their pre-approval for limited category last week before the doors were closed. You shall wait now till the new CSOL list gets updated in August. If you still wish to try, ofcourse you should prepare a list of 6 to 10 jobs that matches your skill set and preferably your industry as well and send a request for verification as there is no added cost to it. If you get rejection, you can keep trying to revise and request.
Good Luck....
