I have seen weatherboard houses with starterboards as the first weatherboard on the bottom. I don't mean the top baseboard, it is actually a different board with a rebate in the top for the first regular weatherboard to start on. They look to be about 150 x 35mm and made of dressed treated pine.

Anyone know where I can get these in Melbourne Eastern suburbs? The places that I have seen with weatherboards don't know what I am talking about, but I have seen them on a few weatherboard houses now, new renovations and old.
