My click clacks are generally smaller than that and hold a gradient quite well via heat mat and thermostat - I have tested my click clacks gradient with the view of keeping Stimmies which I have recently put a deposit on and it holds a gradient between 32 - 22c after a bit of fine tuning with air holes and placement of the mat...

...a cooler gradient should be easier, however, I am not familiar with the weather/temps in Adelaide...

...of course a smaller enclosure makes a gradient more difficult but it is certainly possible with some fine tuning before the snake arrives...
