Hi Anthony, I’m sorry to hear about your dad’s poor health - your post resonates so strongly with me as my parents are emigrating on an 804 visa that takes 30 years to process will not give them PR and as such I can see the same happening to us in the next 10/15 years. I’m sorry to hijack your terrible situation, but it might help my case to have them pay 100k for the 864 so that they have PR in 5 years and cannot be sent back - and so may I ask what visa is you dad currently on? There is an excellent immigration agent in Brisbane - Joey Barnard, 0488115557 she specialises in parent visas and perhaps she can help you with your dads case
