It won't make a difference even if she reapplies from the Philippines. IMO, her overall ties are weak.Hi,
I agree with you. I think she should have applied only in the Philippines not in Australia and instead deposit some money to her account instead of having invitation letter from her fiance and having those bank statement..
Also, what were the nature of her visits to the UK, Schengen countries, etc? For work? Or for holidays? And were these visits paid for by the OP or by someone else?
BTW it is bad advice to deposit money in an applicant's account just to prove s/he has the money to afford the visit. The visa officer is smart to do the math to check if the numbers add up.
If she has set a date for the wedding + booked the wedding venue in Australia + sent out the invites + can have friends/relatives prove they have booked plane tickets for her wedding.... then these documents could help for her TRV app
