There are four species, including two subspecies, of blue-tongued lizards in Australia, and I saw a couple recently.
The shingle-back, stumpy-tail or sleepy lizard (Tiliqua rugosa) lives in the drier areas of our continent, west of the Great Dividing Range that runs down the middle of the eastern states. We dodged them a lot on the roads in South Australia. I handled this tame one at a reptile demo recently.
You can see why they are called ‘stumpy-tailed’ …
A common one locally here in northern NSW is the eastern blue-tongued lizard (Tiliqua scincoides scincoides). The one below is on the floor of an outdoor toilet in Ballina. It likes to eat the snails in the garden, and the many local moggies haven’t bothered it for years. Its defence of opening its mouth wide, sticking its blue tongue right out and hissing loudly has warned off disturbers so far.
