So i have just turned 20 this year and im not happy with the direction my life has taken. I didnt attend year 9 much and dropped out of year 10 to get a job and help pay bills. I want to get my highschool/HSE grad certificate because a different course i want to study needs me to give them said document. Im not really sure on how to go about doing this but I've heard it is possible for adults to get a equivalent of the HS graduation in some way or another. A point in the right direction would be extremely appreciated! (I live in south brisbane if this helps at all)

Not trying to look for a source so to say but more of do i even bother looking in brisbane anymore? Had a few trips a year and a bit ago and have come back to Brisbane permanently but my last guy isnt around anymore and I've had horrible luck finding any. Just looking for confirmation im not wasting time looking in an area if it will be no use. Pm if useful info
