According to Ms Know-it-all aka The Lizard Queen aka @Hermann daughter, this is a Land Mullet, Egernia major. This has been confirmed by Prof Google who reckons that it is the largest of the Skink family of lizards. This fellow was probably about 450mm long.
We came across him up at Springbrook National Park and as is my normal practice, I quickly took a couple of shots before trying to get a better POV. He was too smart for that and quickly disappeared into thick undergrowth before I could climb down the rocks to him. So this was the best of the two quickies.
