Delete if it’s not the right place but does anyone know what this spider is? I opened my garage door and it scared me wife. Sorry about the quality, i had to run out of the garage and take the photo zoomed in (it looked around the same size as a huntsman and looked bigger than the normal spiders we get around here)
The photo is indeed not great, but there is enough here to exclude Atrax spp.
First, OP said he is in Victoria, Australia, that excludes all but one species. And the one remaining is quite rare and hardly found near humans. Asking for location is always a good idea, especially when you suggest spiders that have a relatively small or specific range.
The major visual clue would be the eye sections. Atrax, like most mygalomorphs, has a dome-shaped eye section with most of the eyes concentrated on top. But here we see a much more rectangular, bulky section.
A second visual clue would be the spinnerets, which look too short for Atrax.
