One is OK - but that is potential half of a breeding pair. They have not really got away in Australia yet - but we have to return them to sympathetic vets etc. as soon as possibe. If they get away it could be devastating to hole-nesting birds.

Ringnecks are believed to have been kept in Australia since the late 
19th Century.  The first ones were undoubtedly wild caught and probably 
wild caught imports continued to arrive until importation of exotic 
birds was stopped in the 1950's.   From that time the birds available 
have been aviary bred.
Ringnecks are the most commonly kept exotic parrot, with current captive 
population thought to be well over 500,000 throughout Australia.   The 
majority bred these days are colour mutations rather than the wild green 
colour.  They can be a long lived bird - the oldest authenticated I have 
heard about died at 68 years, and he was still breeding at 67.
It is reassuring that in spite of these very large numbers, and the 
regular escape of birds over many decades, they have never established a 
viable breeding population as they have in Europe.   The reasons are 
probably firstly that Europe continued to allow wild caught imports well 
into the 1990's, and that the wild populations were derived from escaped 
wild caught birds - domesticated birds have very poor survival skills in 
the wild.  And secondly in Europe there are no real competitors for nest 
hollows,  in Australia there are plenty of parrots that will out compete 
a Ringneck for a nest site -  A Rainbow Lorikeet will always win in an 
argument with a Ringneck.
So, while any escaped ones should be removed form the wild, the chances 
of them becoming a pest as in Europe is negligible
