David,
 
There are two categories of Ospreys in New South Wales at present, those that are breeding and those that are not.  The non-breeding birds would constitute those within their first 2-3 years which are too young to breed and older birds that haven't been able to secure a territory/mate etc.  Whether they comprise separate 'populations' depends upon how you define the term.  One definition is "All individuals of a species living in more or less intimate association with each other" (Dictionary of Geological Terms, Dolphin Books 1962).  Some non-breeding birds would be associating with breeding birds at present but whether you would define that as 'intimate' is debatable.  Inland records are most likely of young non-breeding birds dispersing from natal areas.
