What species?

[Aussie]

G'day all just found this ant on a water tank on my property, looks very interesting.
It was solitary and has a golden back and is about 10-12mm long.
I don't think it is but could it be a queen?
Should add this is Australia, NSW/QLD border east coast area.

Struggling to upload photos but am 99.99% sure she is a Golden Tailed Spiny ant, possibly a queen to.

Can't be, has no propedal spines. I'm not 100% sure but my best guess would be that it's a Campotonus sp. The pictures aren't clear enough so don't quote me on it

Is it just a worker?

A worker: yes. But it is not Polyrachis.
