No, of course there are no wardens present. The thing is you do your best within the regs to deliver a humane kill. Might not be that you agree with them but your hunting ethic guides you in your task.
What happens if you were to get caught (Murphy's Law) then all that would most certainly happen would be that your firearms get confiscated and your firearm's licence revoked.
After that you can sit out on your hill and watch the 'roos eat your grass.
Cheers
