yes, it is hard to find (potentially) hardy selections of many different southern hemisphere plants in our area. think that in many cases some plants were selected for selling and growing in places like California where in many cases frost was not a big problem in the first place---eucalyptus IMHO is a good example of this. most of the common species in that state are "iffy" up here but there are in fact numerous species that can be tried up here that can resist a fair amount of cold---just not the same species you see "down south". OTOH, even within nominally hardy species there may be selections/provenances that are more tender (or more hardy) than others with resulting happy (or not so happy) results for the gardener.
you are certainly right that we cam grow a surprising amount of plants from Australia, New Zealand and southern South America---assuming we can find sources of suitable plants.
