Maybe a pycnogonids? Only noticed after looking at photos, so this is the best there is
This observation is for the early instar of the caterpillar in predator mode as it is seen on the right. Preying on Psyllids (Acizzia sp) on Acacia pycnantha.
This is the 6th of these we've found, @ ~4.5mm.
Just reviewed all our finds and posting this to highlight the differences with K. tepperi.

Double Striped Grass Moth (Hednota bivittella)
Very large specimen. Considered to be ~30mm wingspan, this one is ~42mm wingspan.
Based on body I'd suggest a female.
This specimen appears to match S. heterogyna and matches the diagnostic features described in MoV. Part 7
