The Northern Territory is home to the Geyhra arnhemica and the Gehyra chimera, found in rocky ranges towards the Top End.
Gehyra gemina occurs widely through the northern deserts of Western Australia and Northern Territory, with the Geyhra chimera and Geyhra calcitectus found mainly in the Kimberley region.
North-west Queensland has the Gehyra lauta, better known as the "ghost gecko" for its pale appearance, and it can also be seen in bushland in the north-eastern Northern Territory.
If you find a gecko a long way away from people in the bush, Dr Paul Oliver said the probability is that it's a native gecko.
