That is interesting. Looking at GBS data, which is of course only consistently available complied for the first 21 years, the spread of observations of breeding is very wide over time of year. Though very little information really. Note that for the first 12 years of GBS there were no established codes for recording of nest building, inspecting hollows, etc. The few records in that time were all from contributors who participated for many years and had their own codes. Nearly all autumn & winter observations are DY (or F) (no doubt young of the previous year). There are very few spring & summer observations of breeding and can be of any stage. There are no records that suggest an actual nesting within the GBS area or come remotely close. Most are just isolated occurrences of something on just one or two weeks at a site. Mostly this sort of nest building, inspecting hollows type behaviour and DY. Though Geoffrey's obs is earlier than others within that earlier period. Here is the relevant bit of GBS Report text.
Gang-gang Cockatoo Callocephalon fimbriatum

Breeding records have also increased, first recorded in Year 5 then most years since then. Most records are of dependent young. These can be at any time of year, though most are from March to July.

The time of year when pairs of gang-gangs can be seen in the early stages of nesting behaviour, but it is unlikely those local hollows will be used. Rather, this is ritual bark-chewing and mock-house-hunting, probably part of a bonding process before they head for the hills to engage in serious nesting. This pair has been at it most days this week on Rocky Knob
