Include

I was thinking about starting a herp society awhile back and was contemplating the idea of having an auction twice yearly in the form of selling herps and related products.The society would charge 15% of sales for non members and 10% for members.All fees would then be contributed back into the society for such items as books for a library etc.I would limit 5 items per lot and 5 lots per person. Anyone know if that is legal in NSW? What I mean is I realise reptiles can not be taken from the house they are licencsed under but can you get a permit for this reason above?
