Thanks for all your replies. Been mulling the situation.
I note the advice and will seek it, once I have committed to making application.
Can I ask for any advice on the following - if I am lucky enough to get the RRV, there will be times I will need to return to the UK, not often maybe once a year. Is it feasible/possible to leave Australia once an RRV is granted ? I think reality is I would only get a 12 month RRV at best. I just don't want to be in Australia and not able to leave to sort out important financial affairs, it would impact me severely.
Really appreciate any thoughts.
