i'm not as familiar with the cowell, cleve, kimba bit, although you definitely won't see any white pointers at kimba. there is some incredible remnant bush that way though. Gawler ranges is pretty special, there is some nice areas in the cleve hills. there is also a back road from south of whyalla to kimba through a place called secret rocks i think. unsealed road with amazing remnant bushland.
i am on the west coast side and i think we are the overlap of eastern browns, western browns, peninsula browns, dugites and king browns. most of the other snakes look brown at 110k's per hour as well.
plenty tiny dragons running around at the moment. i think they are either malle or painted dragons, but they are travelling way too fast. have also seen a few western bluies recently. we have one thorny devil which was roadkill in the freezer ready to go to the museum. they are supposed to be reasonably common, but i've never seen them (alive). did i mention the sleepies, tons of sleepies, try not to run em over! i had some fishermen in the area i work take out about 20 the other morning!
