Here is a preliminary study which indicates an interesting trend of return migration to rural areas.  The study draws on ABS 2011 statistics of in- and -out migration, cross-indexed against demographic groups.  It seems to show that there has been a net return migration among younger people, in their 20s, drawn by more affordable property, a desire for a community base in which to raise families, and the values which can go with rural communities.  The effect is strongest in the regional areas nearest to Sydney and Melbourne, but can be traced quite widely, especially into rural NSW.
