I'm two hours north of Melbourne, and most definitely noticed it!
I actually didn't feel it as such. I was outside at the time, first sign of it was a rumbling sound like a a few trucks passing on the highway, then the windows of the shop started to shake quite violently. I turned around and was greeted with some very concerned looking customers. My boss was indoors at the time and said the whole building was shaking. I also noticed the water in our bird baths was swaying from side to side, not shimmering, swaying.
The first earthquake I have experienced. Every customer from then on had their own story to tell. I did laugh at one who remarked at least it gives us something other than Covid to talk about.
