It can differ from Uni to Uni so you might want to check. I know UTAS (who aren’t taking non-standards as of this year unfortunately), just look at your last three full time equivalent semesters. JMP might just look at your last two full time equivalent semesters (I think - based on @lbog’s entry to that program). For an incomplete degree, WSU will use whatever is currently higher, your ATAR or your GPA.
Some universities have 85%+ = HD = 7.00 (rather than 80%+) so that would also be something to double check.
And yes, you can definitely use an incomplete degree for Bond, UNSW, JCU, WSU, and JMP. A complete degree is needed for GAMSAT unis and Curtin.
