Name the city that has the same name in two countries given both country names.
Example: United States [Vancouver] Canada
Some countries may share more than one pair of same name cities, however if that is the case, the answer will be the most obvious one, like in the case of Greece and the U.S. which share multiple city names.
There are a lot of similar cities between Australia and the UK, I chose Newcastle since it is a relatively large and well known city in both countries.
