Hello dugles,
Thank you for comment. My occupation is 'Welfare worker' which I'm afraid coming under 'Schedule 2' in WA. As a result, I need to show a job offer in order for me to get back there. I tried to get a job offer, but as you can imagine its not yet been successful. All of them asked for a valid work visa in order to give me a job. That's why I applied for ACT nomination as I do not require to have a job offer. But they denied my application as well because during my stay in WA, I never visited Canberra. Thus they don't find me as a genuine applicant.
I really don't know what to do anymore
