Reading the replies all interesting - leaving you possibly more confused than before.
It is only the mid point of the tourist flying, the longer you are around and the operators KNOW your around should put you in a better place than those who rock up at the beginning of the season.
Seems wherever you chose to end up getting paid employment won't be a problem, whilst things may be flat now you never know when someone's going to chuck it in/move on (or be moved on) and this can happen at anytime of the year.
Although the tourist season dries up in the wet that is (in a small way) compensated by flights to communities/stations due cut roads etc, have to look at what sort of fix of flying each operator has.
If you need $$ and not too worried about getting out in the big bad world I'd pick a town/area (opinions of "best" places will vary quite a bit), settle in and see what comes along.
Along the way certainly clean up the paperwork/studies etc as much as possible or is useful.
I think Roj is correct regards sitting home down south waiting for a job up north - most unlikely.
Personally would be wary of Darwin and suggest a better chance in KNX/BME/ASP or similar places, maybe something in central/west Queensland.
Good luck.
