The lack of food choices is a major downside of the treechange/seachange. Just cannot get good sushi down here and oddly enough good farm produce, better off being in Melbourne for the Farmer's Markets there.

Saying that though I do not think it is that much of a downside so long as we educate our children that there is a different life outside of the country. Just as I would do the same if we were still in Melbourne, make them very aware that there is a life outside of Melbourne.

As for is there an exodus, I am not sure. In the past few years I have come across more people talking about a big move, but I think that is more the finally voicing their dreams.
