My biggest advice to you is to keep your identity anonymous on here. It will not be too hard to work out who you are judging by your car, your age and previous occupation. When starting out the industry seems vast, in actual fact it is very small and after a few seasons you will know almost one guy in every company in Australia as people move on.
While pprune is a great resource, operators despise it as quite often their businesses are put through the wringer on here, sometimes founded, sometimes unfounded.
Most Pilots in the industry have heard of pprune, many read yet don't contribute and others keep away from it. Only a small percentage of the guys on here who contribute represent the amount of guys who read it.
Don't mention the 'p' word to an employer, don't let them ever work out who you are. Don't mention dates, things that have happened to you, etc etc etc. Always speak in a general round about way.
Sometimes your views/opinions can be misused or taken out of context and used by people who seek to overtake/under cut or have an agenda against you for their own reasons. For as many great people in the industry there is just as many who are not.
Good luck and enjoy your journey. The topend is a wonderful place to be.
