Hi Bryan,
There's loads of Eastern Brown's and Black snakes here, just the other day there was a large Brown took off (as I walked past) in the same place I'm standing taking the photo of that carpet snake, the brown ended up going underneath the CNC Laser cutter, we just have be careful and be sure that the Doors are closed properly or they get in the house, a few have black snakes and pythons have and are not fun to try and catch them inside, It sounds like a DIY project!  lots of funnel web spiders too.
