Hi Maximus,
It is illegal to keep any exotic reptiles unless you had them before the Amnesty, which i have been told was in 1996. Or you could get a zoo licence, but then you have to pay lots of money on both insurance and the licence, and you have to have a certain amount of people visit your collection each year for it to be a zoo. So the answer is probably no, unless you are rich, and want to have people coming to see your collection everyday. it is also illegal to sell or trade any exotics that were declared before the amnesty. But you could still get one illegaly (if you want to risk your whole collection and suffer a huge fine).
Cheers
PS
Why would you want an exotic python Australian pythons are THE best in the world, just take a look at American price lists and have a look at how much they pay for Coastal carpets.
