Don't a lot of Swiss people speak pretty good English? I imagine there's a good amount of tourism there too. Even if you're travelling somewhere where little English is spoken, overcoming language barriers can be an interesting experience in and of itself (assuming it's not an emergency). I don't think I really have one ideal place I'd like to visit. I find all sorts of cultures and languages and histories interesting. I'd be happy to travel anywhere where (1) there's a lot of interesting stuff to photograph, (2) there are no giant bugs or really hot weather, and (3) I have a decent chance of not dying.
I've been to Switzerland, and all over many countries in western Europe, and plenty of people speak English, especially at the places that matter like train stations, hotels/hostels. Everything else, even if there is a language barrier, is a fun experience. Buying things isn't that difficult, ordering food on a menu can be an adventure but entirely possible, and I found it to be not bad at all. The only place we had a really extreme language barrier that we encountered was out in Normandy region of France. NO ONE spoke English, not at our hotel, not at the train station in Caen, and not at any of the bars or restaurants, and we still had a blast there, and despite the language barrier, everyone was still extremely friendly and constantly smiling.

Australia is not the place for you, my friend
