Hello SimonI am British and my wife an Australian citizen. I recently applied for a 309 off-shore visa and got it in just over a month. Admittedly, we have married for over thirty years, but if you can document ten years together convincingly, then I hope that you would stand a fair chance of getting both the 309 and the permanent 100 visa granted together, as we did. I was surprised at the cost, but you only have one life. See the recent post from “Fat Kangaroo”, which suggests to me that applying within in the UK is faster than onshore, since onshore Australian processing offices appear to have their hands full.
Good luck for you - well done. Quick question for you as you have just recently filled out the 309 forms on line -- are the questions online something we need prepare information for or is it just filling out a bunch of questions. I just don't want to pay and then be told I need to complete the application by X date - as my wife and I travel a lot for work and I can image filling out 27 pages [apparently] will take us a month or 3
