Ok these are from 2006 NSW records but give you a general idea and trend. The most popular kept pythons in order are Diamond Python, Carpet Python (subspecies unknown), Children's Python, Spotted Python, Eastern Capet Python. So yer generally speaking the Carpet Pythons are the most kept in NSW during 2006. I would suspect that Central Carpet Pythons and Stimson Pythons would of since made it in that top 5 somewhere. The most desired well that could most be all the pythons but probably the most expensive ones.
