Unterwegs, thanks for confirming the itinerary is doable.

Yes, adding Australia would be great, and will seriously consider it.

I suppose MAD is not so good as a starting point, but where then? I've searched the forum and couldn't find european alternatives that made sense to me; price is pretty much the same all around in europe, except the uk, where's much higher; and MAD is where I live so I'd still have to get to/from the alternative starting point; cheap enough to find a tkt, I know, but what would the benefit be? not arguing, just curious.
