A tip from mine would be to stop moving around so much. Need to be Johnny on the spot. Pick a location and stick to it. ie Darwin or Broome.
When I started out, 3 people were hired in a 12 month period and 2 of those had the job before they arrived into town due family connection. Keep at it, one day you'll reflect on the journey and realise it was well worth it and that flying a piston single around was the best job you ever had.
