There is TAFE but if your on 457 it's international fees, you don't pay for public schools in qld, my son was in his final year in uk and we come over jan he started year 11 here, they do year 11 and 12 for their op which gives them a score to go to uni etc they can also do an apprentiship through school one day a week starting year 11 all free, my eldest started school mid march, he graduated in November from public school no problem with a high op, good luck x
