I believe that Coffs Harbour Zoo was a member of ARAZPA, and so I'm sure that the dispersal of the animals will be handled according to their normal procedures, but as far as I know, they don't have capuchins (did you mean tamarins, Nigel?). The only primate species they have are cotton-top tamarins.
The species coordinator will recommend suitable institutions for the tamarins to go to, after talking with the appropriate curators and/or directors.
