Without a decent photo of the bracts under the flower head and of the leaves it is impossible to say whether this is Pimelea trevaudi (leaves 1.5-3.5 cm long, 4-6 mm wide, 8-10 bracts) or Pimelea ligustrina (leaves 1.5-5 cm long, 7-18 mm wide, 6-8 bracts). It is definitely not Pimelea linifolia.

I've added some cropped images with a close up of the bracts and more of the leaves. I think in most images the bracts number at least 8 and the pattern of colouration seemed correct for Pimelea trevaudi. However, I discarded this identification because the PlantNET descriptions for both Pimelea trevaudi and Pimelea ligustrina had leaves for these species with secondary and intramarginal veins prominent below and I could not convince myself that I could see these on the mature leaves, they seemed only visible on new current season leaves with the light shinning through. I wasn't happy with Pimelea linifolia but I couldn't see where else to go.

I use Flora of ACT whenever possible for identification. The descriptions in it are usually based on local material. This is Pimelea treyvaudii. There are the correct number of bracts, which have a long point at the top. This is a common species at lower elevations in the ACT. I would not worry too much about the fine detail of descriptions in PlantNET, which are very rarely based on ACT material. Local botanists nearly always deposit their specimens here, not in Sydney.
