Never heli-mustered but did plenty on bikes and horses.
Early mornings, late nights, use the fenceline, always drive to boreholes whenever possible and be prepared to not eat beef for a year once you finished your tour. Use your fellow jackaroo's (cowboy, to non convicts) toothbrush to kill the frogs in the Belgian sized shower, when you're near one in order to keep King Brown (not James), Tigers and Taipan snakes away. And take it from me that a one tonne bull can jump a five bar gate without knicking his testiculaaars as long as you leave it right at the last moment before jumping on the f!!!"*'/??S back. Good luck.
