That's all fair enough bigguy, all I was getting at is that when I first wanted to do what I did members here told me I couldn't because of this that and the other clause in my license, because it was important to me I contacted NPW and asked them directly and got a definitive answer and I'm glad I did. Also depending on how the school has organised things and assuming they have been in touch with NPW, then the public liability no longer falls back on the owner of the snake. Because I organised things the way I did and went through the principal of the school etc it came under the school's excursion policy and the department's insurance.
As an aside to all of this, I would be curious how the kid got bitten in the first place? As a means of rsik management I don't allow the kids to handle my snake and I don't let them close enough to the business end to get tagged.
I am not an expert in these matters by a long shot but at the end of the day I encourage people to confirm what they have been told on a forum by contacting the relevent authority, often times there are 'loop holes' for want of a better word that may apply to the individual case at hand.
