You are right CollegeGirl, I don't want to expose the problem in the immigration office, but until now I made a mistake, I don't think that I will be deported, and the mid semester break or the visa was designed to catch people that want to work in this "mini vacations" to pay the expenses of studying here in Australia.
Although, I want to know what would happen to me? A visa is not like a bus ticket, there are so much to consider for any action and I want to be ready for the worst... I don't know....
