Defintely not any lily or iris, with petals in 5s rather than 3s and 6s. So not Tricoryne. It vaguely looks like Hypericum but the arrangement of the flowers on the stalks is wrong. Unfortunaetly even when I blow them up, I can get little idea of what the stuff in the centres of the flowers looks like. The leaves are small, opposite each other, and reddish. Stems reddish.
I have asked Jackie Miles, who has done fieldwork around Delegate, for her comments.

Would you like a better photo of a flower?
   6 Jan 2019
Yes please, concentrating on getting the ovary(s) and stamens in focus. Also of the reddish stems and leaves. It was quite hard to find them in among all the greenery.

The flowers look wilted and the red in the leaves and stems is also a sign of water stress.

Hi Betty, I've compared it with my Hypericum gramineum photos and it doesn't look right. I don't have any with branched inflorescences like that. An in focus shot of the flower would certainly help! A possibility is Linum trigynum - the shade of yellow looks right, and the branched inflorescence. My photos show alternate leaves on that species and these look like they might be opposite, but it's hard to be sure.

Yes, Linum trigynum looks the best bet so far, except that the leaves on these plants as far as I can see look opposite each othe. https://apps.lucidcentral.org/plants_se_nsw/text/entities/linum_trigynum.htm
Blackflat, could one of your new photos show several leaves and their attachment to the stem please.

The flower here is quite different to Linum trigynum.
Also I've seen plenty of specimens with branched inflorescences. See:

Thanks Michael should I delete this sighting if it’s the same type of plant in the same area. The other image is much better.

Hi Toni
There is no need to delete the second sighting. The Timeline feature has a radius of 100m. Looking at the maps it appears they are some distance from each other. Even tho it is a repeat it is a learning experience.
