Compare also with Backhousia subargentea (synonym: Choricarpia subargentea) .
Has stamens tomentose .

Also growing in the botanic gardens there .

Whereas Backhousia leptopetala has stamens glabrous (hairless) .

In these photographs so far i could not quite make out whether these stamens have hairs on them or not .

More possible candidate species especially in this Myrtaceae botanical family and a few more botanical families i suggest as candidates such as Cunoniaceae eg. Callicoma serratifolia .
To check .

Nice pictures, Dianne - I can't see the hair spots on the thorax found on M. macularis.

I guess from experience memories this possible candidate species ... :

Thank you Rosemary Purdie ( @RWPurdie ) for the experienced clear-thinking comment above just now, bringing me to look at this sighting just now .

Please carefully check out the flowers of :
*Backhousia leptopetala* (synonym: *Choricarpia leptopetala* ) – NatureMapr species page : Backhousia leptopetala .
Eg. @plants sighting : Backhousia leptopetala (Brush Turpentine) in Stanwell Park .

And let's check the botanic gardens plantings in the field and
in the gardens inventory if this species or a related species has been planted and grows as a tree here above this spot ?

My guess is that the photo is of about seven 'spent' flowers that have fallen from a tree, the base of each flower (we're looking at them side-on) showing 2-3 yellowish sepals and bundles of purplish-brown stamens that have been caught up with each other to the form the single 'mass'. The anthers are very small but visible in a couple of the photos.
