This is an unnamed species of Psychidae which I initially matched to to "undetermined species A" on the Butterfly House site and Cathy then located on Australian Moths Online as "Unplacedtogenus xanthochrysa" - see second image
This is also the female of the Undescribed species however there is a major loss of scales on the wings. It gives the appearance of brown colour and you can see the wing veins clearly. There is also some damage around the head area. Surprising she could still navigate.
