The Loved Ones (2009) is an ozploitation masterpiece that doesn't seem to get mentioned much here.

Ozploitation/awkward teen sex comedy featuring two of the most hilariously demented (and HELLA problematic) villians of recent memory.

Is it torture-porny? Sure. It's honestly gnarly af, so definitely not for everyone. But to me this can stand shoulder to shoulder with Wolf Creek in the ozploitation pantheon.
