Hi
Thanks for your replies, we won't have any stopover en route. Problem is If I need to get new UK passports that will take until end of January 2020, then I will have to fill out the form to change their current visa details to their new UK passports. I am wondering if Australia immigration London will be able to change their new passport details with thier PR visa. Does anybody know if it's a quick or slow process for Australia immigration in london ?
Thanks
