I think likely a juvenile of Hypoblemum scutulatum (or Maratus scutulatum), same as a few others from the same area I'll be posting. Posting separately just in case they aren't the same, also because I got great photos of each. ;-) Hornsby area, Sydney.
Just going through this collection of your sightings @KorinneM ! They are indeed the same species, and can be put under one sighting next time if it so suits, as accurate abundance data can be valuable too. Love your enthusiasm and the photos are superb! :)
@YumiCallaway it wasn't a species that I'd encountered juveniles of before, so wanted to be on teh safe side. I am giggling slightly looking back at my 'younger' self with wanting to post also because I was happy with teh photos. Thanks for IDing!
