I'm excited to share that we finally, after 17 months, received our visa on 6 September.
I'm South African, husband is Australian
Applied: 30 March 2018 (PC and medical included - applied ourselves)
RFI: 12 July 2019 (new PC's for me and husband, new medical and form 4009)
Documents submitted 15 July 2019
PC submitted 6 September - Visa granted 1 hour after PC was submitted.
First entry by 6 September 2020
I've been granted permanent residency - My husband and I were in a relationship for 3 years before applying and have since gotten married and had a baby, who has Aus citizenship by descent.
Although it's taken a long time, my husband and I were lucky enough to have been together the whole time, he has been working in SA on a temporary resident visa. Now it's time for us to plan this move back to Aus.
Good luck everyone and thanks for all the assistance. This forum really helped us to get my visa application together.
