While it maybe referred to by many things - to avoid confusion just call it a PMV.
Just get an NOIM in Australia - no big deal most are never the right date and you can change and do any marriage any place with anyone as long as it is a recognized legal marriage by DIBP.
You need to enter Australia on the PMV once granted - then marry (any place) within 9 months of the grant date, not your arrival date in Australia.
The process is long, expensive and lots of evidences (or future/s planned for all 4 relationship categories) need to be supplied.
