That is great to know. It is consistent also with the text of my Canberra book 
as below (relevant bits in bold). Even with few breeding records I commented on 
that. Extract from page 72-73.
New Holland Honeyeater Phylidonyris novaehollandiae

This species shows the least regular pattern of all the honeyeaters but that 
may be related to sampling problems. It has its greatest population density in 
coastal heaths where it can be superabundant. It is very active, sociable and 
noisy and unlikely to be missed. Locally populations are found at the 
Australian National Botanic Gardens, where diverse plantings of Grevillea and 
other natives provide constant food sources. It also occurs along the 
Murrumbidgee River Corridor and other sites, where there are large stands of 
suitable shrubs. This species can survive as individuals for some time and even 
breed as isolated pairs in the suburbs and there are many such records. 
However, it is the occurrence of large groups that contribute the greater part 
to the measured abundance. In our region it appears to show two patterns that 
are superimposed. It has the winter peak and summer minimum of most small 
honeyeaters but on top of that it has a marked late summer to autumn peak as 
well. There is even the impression from some sites where they are recorded 
regularly that there is a gap in their occurrence between the winter and summer 
peaks. This results in the odd arrangement of lows during spring and autumn 
having similar mid-range abundance to summer. Abundance has varied widely. It 
is reasonable to believe there is some real effect in this as the populations 
of these birds naturally fluctuate according to nectar availability. 
Interpreting GBS data is complicated by the changing distributions of both the 
sites surveyed and the locations of colonies of this species affecting numbers 
observed, for this species apparently rather more than most. The summer peak 
was greatest in those years that had one or several sites at the Australian 
National University (Acton) that is near to the Australian National Botanic 
Gardens and so is influenced by that large population.

All three breeding records include activities with young in the nest and 
dependent young. The duration 5 to 7 weeks is consistent but the timing of 
these events is diverse. In late November to December in Year 4 and late 
February to mid April in Year 5 at Site 105 and mid August to mid September in 
Year 16 at Site 152.
