Page 106 of The GBS Report provides the graph (and the text on page 69) of the breeding timing of the Red Wattlebird (and other species), so addresses
the timing issue. But this is only for the first 21 years of the GBS (1981 to 2002). There has been (little or) no attempt to keep the information consistent, available, compiled or up to date since then.
So yes, it certainly is very early but not without precedent. The suggestion of this being to beat the Koels has been put forward often over the last
few years. And appears to be a nice idea to explain what could be happening. There can be lots of factors that can influence timing of breeding (or changes of timing). A comment a few days ago about magpies jumped at the idea of climate change. Note that
Koel had not yet been recorded breeding here within the period of The GBS Report (page 61), even though my text shows that I expected it would happen soon.

Is this “early” fledging of a Wattlebird to beat the arrival of Koels & their effect on successful WB breeding
