Not strongly marked, there are several similar looking species. Agriophara dyscapna? https://biocache.ala.org.au/occurrences/7a872fa8-f8e9-46e3-80b4-7b171e911aab
Maybe, but this moth has much narrower wings than that moth and does not hold its wings tent like. This looks a bit like a Stathmopodid but does not match any. Despite a prolonged search of Gelechioidea I have not found an alternative suggestion.
Some specimens of M. automima lack the dark brown marking at the base of the forewing behing the thotax, See here:- https://lepidoptera.butterflyhouse.com.au/chez/automima.html
Yes, the black tips to the palpi are apparently diagnostic for Ardozyga porphyroloma. The ALA is consistent with the AFD which ecognises A. porphyroloma as a species but not Epimimimastis porphyroloma.
