Thank you Tony Daley for confirming the id of this species for us

General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
~3.5mm long. They look much larger, but that's because nose to wing tip they are ~6.5mm long, and have a 14mm legspan.
Like all long legged flies, these are also metallic, but it's not nearly so obvious as most.
It's difficult to know with such small insects what is a real colour and what is a camera artifact as they just look like a little blur with the naked eyes (with with mine anyway

Similar to our other water floating fly, which is a different family.
This one has a line of white hair through the bottom of it's eyes and two white stripes on it's back that are made up of *very* short white hair.
Notice how green S9 is compared to those photographed outside - possibly camera artifacts?
