Zulu the very link you used before, the bioatlas, has a number of records for the white lipped pythons from the QLD museum, most originating from PNG or Indonesia. There is one entry with no locality given which may or may not be one of the two "Australian" specimens they are purported to have. According to the "data quality tests" for most WLP's in Australian collections (notably the one specimen within the qld museum that has not originated from Indonesia or PNG) a lot are missing significant values i.e. date of collection, missing geodetic datum, decimal co-ordinates not supplied, missing name of person who identified the specimen/observation plus a whole raft of others. I think that strengthens Jamie's point about collection data. No-one is taking shots at Cogger, but his information is still only as good as the data available within the museums collection which as Jamie has stated can at times be quite old and potentially highly inaccurate.
