You could try constuction.
Other options though might be to do a little time at TAFE and have a shot at a basic government job, like centrelink (with a cert 3). If you like tafe maybe you could do an 18 month diploma (harder though- But easy to get into than an apprenticeship or trade) and then the sky is almost the limit and it opens up options like the Fire Brigade, Police and work in private firms.
Another option, which ive even contemplated as a fall back is have a shot a State Transit Authoirty driving a bus, you dont even need a MR permit just a drivers licence
