have you tried considering enrolling in a TAFE program? Program that suits your qualifications, they have lots relative to your field (elect.)
Catch is you need to shell out tuition payment, as i believe you need to pay in cash and this is not applicable thru HECS.
Have a look at the link below:https://tafeqld.edu.au/
once you completed a course (of your liking), you'll received a certificate which will easily enable you find a job.
hope this helps, one day soon, you'll hit the mark and get the job you want.
