That, within a context that there are not a lot of GBS observations at nest for any of the cockatoos, even the abundant ones. So this is not surprising for a still relatively rare species. Most of the available breeding data for cockatoos, indeed parrots, from the GBS, are from the post fledging periods, as in data on dependent young. Most of them have nest sites away from people's houses in the woodland around Canberra and the families come close to the suburbs after young have left the nest (and are conspicuous).
 
I would also like to clarify that there is a difference in terminology between "records" (as defined in the GBS Report) which relates to standard terminology of database structure as to what is a record, compared with observations (or as Martin writes: "occurence records". I can be confident that the quote "43 occurence records are listed" refers to 43 observations (a species at a site on a week), not 43 records (a species at a site on a year). As in the first 21 years there were only 8 records, comprising about 25 observations.
