Thank you for taking time to reply.
I am not sure your permanent residency works like that re retuning every year and then going again. Once your travel part of your PR lapses then you need an RRV. And they are not indefinite nor do they keep handing them out year after year if you don't show any intention to actually reside in Aus. I would need to complete right to return yes. Immi agent says if my wife has family that is enough and I would need to return for at least 1 day (cost $300 for right for return extension)
The leave in April and then have 10 years PR am not sure I understand. By April 2018 I will have accrued enough time in Australia to extend my visa for another 5 years from 2021 when my current Perm visa expires.
TBH none of your options really work for me but that is me. Its not about what I want, its what you and your family want for the future, short and longer term. What option would you create?
You can make all the plans in the world and find they unravel once you've made a move as time moves on. Some for the better of course, if its what you want, but some perhaps not.
Your daughters are getting older and will soon be off living their lives. If you moved to the UK would you be living close by enough to see them often? Is it a part of the UK you would like to live and work for a number of years? We could live close. We would meet atleast once a month or more.
If you remain in Aus does it have to be Sydney or Perth? Its a vast country and if you are happy in Aus and wanted to you could explore other options in terms of somewhere cheaper to live with decent job prospects. Doesn't have to be based near a big city. The eastern coast is more densely populated and I would hope there could be other options along there somewhere or another city. Preference is Perth due to family and cost but Jobs are fewer.
Also can you even move to the UK currently based on the UK partner visa rules and regs and the costs etc involved in this? It requires a fair amount of money or a job secured. The visa isn't anything like the Aus partner visa and is much more constrictive to many who want to take their partners to the UK. Many simply cannot return with their partners and so have to remain living elsewhere in the world. My wife is UK and Australian citizen .
Thanks again for your thoughts
