BLUE TONGUE SKINKS

I have to do a final project for my Geographic Information Systems class and one option I was considering was ranges of the various Tiliqua species. Does anyone know of any websites that have spatial data files or surveys of reptile populations in Australia? I'm feeling that I'll be better likely to get information for the Australian species, though any data for the Indonesian species would be welcome as well.

I've started looking at several websites, in particular http://asdd.ga.gov.au/ and http://www.environment.gov.au/

So far nothing specific on Tiliqua, but I'm hoping to hit on something that has some data pertaining to the subject.

The data is only for New South Wales but might be a good starting point.

Thanks! After searching around, I think I might have to go on a state/territory basis and hope they might have more in depth information on their various websites. This is a good start for NSW.
