A whole truckload of nopes

This one looks like a Allothereua maculata. It's found in Australia and is a predator of insects and other arthropods, but is generally considered harmless although it does indicate dampness and a lack of ventilation in the house. If you're sane and so don't live in Australia and get the Scutigera coleoptrata version it also eats other insects and spiders and is harmless.

Why Australia, why?

It may have not been this exact insect but it look a lot like it
