Oooooooh a Redback! and a big one too, there were loads of redbacks at the house in Ararat one actually landed beside my hand when i was fixing a door frame, quite disturbing having a deadly spider land beside you but you get used to it pretty quickly, I would be more cautious of a whitetail looks kind of the same but you guessed it, it has a white dot not a red one if they bite you the bite never heals ever! and we seen a lot of those too!
