There is a potential problem with Max's solution if one suburb name is a part
of a subsequent suburb name, or if a suburb name happens to also be a street
name. The problem arises because Max's algorithm does not check that the
position of the match is at the end of the string.

Of course, even with this solution, one could still have suburb name
combinations that would return unwanted results, if the repeated word were at
the end of the suburb name, and occurred first in order.
