Yes resembles Ipoini. Might be Ipoella fidelis, said by Fletcher to be common, see Fletcher, M.J. (2009 and updates).

Hi Christine I noticed there's been a discussion of the ant in this picture as being of possible interest here Notoncus gilberti (Smooth Epaulet Ant) on 2 Nov 2018
Hi Ryu, thanks, I saw it too. I am quite confused about the identification of ants. I will try to find any other photos on my camera to see if I accidentally got any clearer ones of the ants, and will put a second sighting for the ant.. probably tomorrow.
