the only options for the first year with a Non-O is the banked 800k or an Embassy affidavit (65k monthly can be done from year two onwards). The combination method is very rare these days.
If the OP entered on a Non-O 4-Nov his extension does not start until those 90 days have finished then that day becomes day 1 of the first 90 day report as he is starting the 12 month extension which was received 24-Dec.
You cannot get a Non-O in person in Canberra so it's either an in country conversion or visit a neighbouring country if the eVisa approval times for Australia are too tight for your flight date.
