Fantastic @Anna1403 and all those who are doing the same thing. I've just started hosting (The Summer House with bush backyard at Bawley - Bawley Point, Australia) and I'm very keen to see all these great sustainability ideas. Our place is already somewhat off-grid, with seep system sewer (off-grid absorption) and all water via roof harvest to tank.
We have furnished the house with recycled furniture and use a wonderfully sustainable toilet paper by "who gives a crap".
We plant from a list of original native plants, since we are in a pristine area and seriously owe it to the land and the original inhabitants of the Murramarang Aboriginal Area.
Next will be solar, a battery and tips on local sustainability.
Cheers Martin & MaryEllen
