Hi Saxon. Welcome aboard.
As SniperCap has already mentioned, decide on what species you'd like first, research the species and ask questions if you're not sure. then get your license sorted out. then organize an enclosure and get it setup and temp tested before purchasing. Getting the python is the easy bit- a suitable enclosure seems to be quite a problem for a few people.
On the plus side, living in Qld means you won't have to go overboard with heating.
