I'm not 100% sold on your focus, but I'd suggest finding a nice bit of the sky with no nebulas or anything of interest and take an exposure with nothing but the stars.


I'm seeing that the trailing isn't all in one direction which makes me think that it's not guiding/alignment , rather backspacing. An image with nothing but stars will help figure it out. Given you're in Melbourne we should have a clear night by 2030 ........


Edit, I've added a picture to give you an idea of how incorrect back focus can affect the image.
