I lifted the cover off my push bike today and discovered 15-20 of these insects all along one of my brake cables.
A few were tending to "egg" like structures that were stuck to the cable and stood out (I've since wiped these away).
I've never seen these before and haven't had much luck Googling or reverse image searching.
They have black "ant" like bodies with orange/red dots on their back. The same orange/red is present on the tips of their "feelers".

This was in Queensland, Australia.
