Thank you Marilyn Hewish for identifying this species for us

General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
This is figured in Moths of Victoria part 5 as Nisista sp. (3)
Maryilyn said "It's tricky because the transverse lines are almost invisible .... I recognised it by the pale grey colour, thoracic crest which goes a long way forward, and the pattern of lines along the outer part of the forewing"
The black blotches on it's forewings are more obvious to the naked eye.
The sharply pointed, forward facing, "mane" can be receded by the moth at will. Possibly a defense mechanism to make it appear more aggressive or larger?
Gender can be differentiated by their antennae, with females being thread-like (filiform) & males being bipectinate.
Don Herbison-Evans has enlightened us that the wonderful mane these animals have is called a "Thoracic Crest", thanks Don
