485 partner visa support

Hi,

I am planning to apply for 485 visa next month. I recently got married and want to add my wife. She came here with visitor visa (subclass 600) 2 months ago. Her visitor visa says 3 months stay from the date of each arrival with multiple entries till October 2025.
Does she needs to visit another country to show the 3 months clause? Or
Do I just add her to my 485 visa and she can stay with me on bridging visa till I get the 485 visa?

Please help.

Her Visa conditions:
8201 - Maximum 3 months stay.
8558 - maximum 12 months stay in 18 months.
8101 - No work.
