It was HYOOJ!!
I grew up at Moore River and the joint was thick with them, they seemed to particularly like Agave stands. We used to have be careful playing chasey in the bush, was terrifying when you ran into a web. Have seen them eating sparrows too.
What about this evil looking fecker?
I've only ever seen two of these horrible things, one was on the track between Wedge and Lano, I thought it was a Funnelweb and captured it and took it to the museum for ID. And the other was in my sisters shower at Two Rocks, arched up in attack mode coming at my foot. Scared the piss out of me!
Nope Mouse Spider Pup, very closely related to Funnelwebs and just as toxic. Very widespread across Oz but also very reclusive, the female never leaves her burrow and the male only travels to get laid after which he ends up dead. Funnelweb anti-venom is effective should you ever have a run in with one.
They're part of the mygalomorph family which contains just about every nasty, evil looking spider on the planet, Tarantulas, Funnelwebs etc 360 million years of evolution all rolled into one nasty creature that can bite through shoes, fingernails etc
got a feeling I've seen one over at Nth part of Garden Island quite a few years back near the old banana plantation & the Well - and this beast wasn't small either!!! remember the Uncle telling us it was a Wolfie which was why I asked Mick .... geez though fingernails bugger that 
Didn't squash it , the Uncle grabbed a stick & flicked it into the scrub
I didn't know there was a banana plantation on GI, could've been a Northern Funnelweb too if the nanas were imported from QLD and it hitched a ride.
Wolf Spiders tend to be a more mottled colour than Mousies ala this
Usually not as stocky too, although I've run into some serious beasts turning over logs looking for bait when trout fishing down your way. They're not aggro like Mousies either, those phuckers are the Honey Badger of the arachnid world.
I think originally there was a shack or old home near the well which was gone when we were there .... just the nanas & well - whoever lived there planted a small patch nanas - this is going back years ago Mick too!!
The old man & Uncle used to go for crays round the corner , from memory it looked like your first little "friend" ..... or is that fiend 
cheers ... oh and I may not be all that far from you either atm
