Our countries have a lot in common but I think this is something where we differ (other Aussie's chime in if you feel I'm wrong)....
I hope that people don't take this the wrong way (especially those who run contests), you see us Aussie's are a competitive bunch but well "having a go" or competing is the main thing and more important than winning, we are not a win at all costs society - we can't take ourselves seriously enough for that.
BUT - I think its sad that a friendly hunting competition has degenerated into something where cheating is considered the norm to a point where the winners are subject to a test? Really

There are a few hunting comps here but the winners usually receive hunting products and the proceeds go to charity. I hope we never get to the point here when the winners are immediatley under suspicision. For me, I wouldn't enter a hunting contest knowing that if I won then I'd be subject to a test. If the organisers can take my money to enter then they could take my word for it (and my teams) that what we caught we did so within the rules.
