I don´t know that much about Australian scene beside some of the major and most influencial acts (like SPK), but I would like to suggest the Fanaticism tapes, perhaps the most interesting death industrial (and the closest thing to the Nekrophile stuff) recently released which I´ve listened to. Here a link to their bandcamp:
https://fanaticism.bandcamp.com/When seeing the title of this thread pop up tonight, I immediately thought that I should mention Fanaticism. Quality stuff, with a minimal and effective aesthetic. Dark and mysterious atmosphere all around, from the sounds and visual presentation, to the label simply emerging and anonymously releasing a hearty amount of C60's (I love em long) over the course of two years, and then vanishing once their work was done.
Thanks to your post, I was happy to take a look at their Bandcamp and find that a previously unreleased piece ('Kreuzigungsmesse') was posted last Christmas. Glory to the new born king!
If anyone has copies of the 'On Wretchedness and Sin' and/or 'Ordensstaat / Imperiale Theologie' tapes for sale or trade, please do get in touch with me.
