TV show for kids shown in early 70's do you remember it. I think it was called adventure island not sure?

Does any body remember the name of this kids show in Australia in the early 70's. It was set in cobblestone streets and there was a flower shop and a witch that lived on a big mountain. the show started with big gates that would open. I also remember a short show that came on before it with a house and the lady would arrive at the house and get the mail and go inside and talk to a cukoo clock or something, vague memories but I loved it. No one seems to remember it but maybe you will......
