Going by previous sightings it is Cryptandra sp. floriferous.

The PlantNET Cryptandra key still treats Cryptandra sp. floriferous as a variety of Cryptandra amara. One of the ways they distinguish this variety (var floribunda) is by it having terete revolute leaves, it is a bit hard to tell from these images but I think these leaves look more elliptic to obovate and recurved rather than revolute. Do you have a good close up of the leaves?

It is definitely Cryptandra sp. Floriferous the flowers are the key. C.amara flowers later and has longer bells hence C.amara var longiflora (old name).

Do you have a contemporary key to this part of the Cryptandra genus? The PlantNET key relies on leaf characters to separate Cryptandra sp. Floriferous from other Cryptandra amara varieties. In this key the flower lengths overlap Cryptandra sp. Floriferous 2-3 mm, Cryptandra amara var amara 2-4 mm, and Cryptandra amara var longiflora 4-6 mm. However, it seems these varieties of Cryptandra amara are no longer recognised as warrantng recognition as distinct entities. Guessing lengths from photos without a scale is difficult. There is a lot of variation in flower length as well as leaf length and shape for images of Cryptandra amara on Canberra Nature Map so there maybe some confusion among the identities of species photographed.

PlantNet says Cryptandra amara var. floribunda Maiden & Betche; THIS VARIETY WILL BE A NEW SPECIES, CURRENTLY CALLED BY THE UNPUBLISHED NAME Cryptandra sp. Floriferous (W.R.Barker 4131) W.R.Barker. I think I will call them all C. amara and leave it to the experts, if I can work out what features to photograph (wind and camera permitting).

If you look closely you will see there is a completely different shape of the bell between C.sp.floriferous and C.amara they flower at different times C. amara flowers later in spring. They are completely distinct from each other.
