Brisbane Ant Queen id help

[zestylemon07]

was hoping you guys could help me figure out the genus and if possible the species
here is the info i have for u guys
1. Location of collection: Park area although i see these ants basically everywhere in my suburbs
2. Date of collection: 28 Dec 1026
3. Habitat of collection: footpath next to a grassy park
4. Length (from head to gaster): approx 10mm ( workers that i've seen are typically 1-2 mm )
5. Color, hue, pattern and texture: the body is black, the antenaee are light brown and the legs are lighter brown (getting lighter in colour as u go down the leg)
6. Distinguishing characteristics: the section between the abdomen and the body
7. Distinguishing behavior: very quiet ants, not agitated easily.
8. Nest description: often found in the cracks of sidewalks or just off to the side of sidewalks

We need better pictures of the queen. Also, how can you be sure those workers are the same species or genus?

Despite this, I think it might be from the Dolichiderinae subfamily.

i had seen this species leave the nest for their nuptial flight so i walked down the street a bit (less than 100m) and caught several of this species. so they are most likely the same species i cannot be 1000% sure but was a reasonable assumption

You cannot see it from the photographs, but I guarantee that if we had an image of the tip of the gaster, we would find no acidopore, which is the defining characteristic of the Formicinae subfamily that Camponotus belongs to.
