That is an interesting point.Hi Carllai84. I will just give you my contribution to this. When I got a request for more information last month (January 2018) i was surprised that the CO needed more evidence for my case. I used a lawyer to apply in 2016 and they said I had provided sufficient evidence at that time. The request for information looked a copy paste of the initial evidence for the application.- nature of relationship, financial aspect, social aspect..etc. NOTE that I had submitted all these in 2016. So this time i provided an updated and active joint bank statement, my car rego and insurance showing my current address, more recent photos, previous wedding invitations, updated whatsapp communication, I did an Australian stat Dec, partner and his mum did an Australian format stat dec, i wrote a personal statement, i submitted 2 form 888 from different people who didn't submit in the first go, our updated timeshare paid off, future travel plans..etc We gave them more information to prove that our relationship is still genuine and on going. So I would suggest you dig up all the strong evidence you have since you applied and submit to them. It has been 3 weeks since i submitted the evidence and i have now been asked to go for my medical assessment.
So just give them what they want and good luck!
They may be asking for more recent evidence, to prove the relationship is still ongoing, but not wording the question correctly...
Maybe they need feedback on that one..
