These two spiders were found in the Northern Territory in Australia in July (winter time). Both arachnids were shot during the night (I suspect them to be nocturnal), and both were found close to the ground. They do not build webs I think (way too big).
The upper spider is quite big, pretty much hand-sized, and about as big as a bird-eating spider. I think the guy with us told us it was a species of wolf spider (if I recall correctly - I'm unsure). The bottom hairy spider with its nice camouflage is somewhat smaller (if I recall correctly), but still well sized.
I have been searching for their names, but the amount of spider species is overwhelming and Australians tend to focus online resources on the poisonous ones. I'm fairly sure these two are harmless.
