Hi C22
The last post I made in this forum was January, We left Darwin in April and have happily settled in Cairns.
We are very happy with the decision, whatever the future holds.
I contacted my original London based mara registered migration agent, they confirmed that we could move to another listed regional area, would not be in breach of our visa and that is all that matters.
One thing I have learnt in this whole process is not to get lost in forums for answers or opinions, everyone is different, get profession advised based on your own circumstances.
All the best
