As an Adult and on license the good old Eastern Blueys, can't kill em with a stick. When I was a kid back in the 70's and early 80's we use to catch and keep for a while all sorts, Blueys, she oak skinks was a common one,water dragons, water skinks, Diamond Pythons and when mum didn't know baby red bellies. Keep em for a week or 2 and then take them back and find something else
