I am using a OAG
I called my explore scientific thing a flattener - my mistake - it is a coma corrector
I use a CEM70 and my tracking is usually very good - during the night in question I was at 0.5"
last night, I setup to take samples to show in this thread, but my images were back to normal (for now at least)... so it's a mystery

Interestingly, I tried to get some imaging done on the 28th in Melbourne, as you are, and I had what I would consider identical elongated stars as your images on my C8/AM5. All across the field of view. I thought it might be collimation and check with a Tri-Bahtinov mask and collimation was good. Clouds came over around 11pm so I gave up and never saved any images.
Something atmospheric?
