I suggest you do a search on Rebtel and start using this if you can so that you get (1) Cheap calls to her and (2)Phone call statements that you can use.I dont have phone records cuz we are using prepaid phones there.
That would help if you had held it for some time, not 2 weeks prior to the application being lodged.If we get a bank account with our names on it, is that a strong proof ??
Any joint assets in the Philipines?
Photos are going to be very valuable to you, along with very good relationship statements and stat decs (or the equivalent from the Philipines if there is such a thing).
Has she ever been here? If not maybe try for a tourist visa for her first to build up some of the stuff you are going to need to support the application.
Don't do the medicals until asked to do so. It is DIAC policy, don't annoy them. They could even tell you to re do them. Besides it will not hold up the appliaction, 10 months remember.
