A couple possibilities (I'm not yet fully decided). May do at least part of the time what the OP (Louie) did. At least part of the time will be staying with a friend in Adelaide (so, even though not explicitly heavily subsidized housing costs, the housing costs will be shared/divided) so depending what work was available there nearby at the time, that would affect things. Possibly some of the time doing harvest work/grape vine training/etc. (the grape vine training thing was actually suggested by my friend).

But I had to submit the visa application right away because in october I hit the age cutoff.
