For years, Bing maps has totally relocated dozens of Sydney landmarks around the city as it indiscriminately treated X street in the CBD as X street in another suburb, Notifying them of the scale of these errors (via feedback, twitter etc) has been a thankless exercise.
Bing also has a gift for identifying the main location of some institutions at minor branch locations. It placed the University of NSW in Manly for several years, and now places it at the location of its small College of Fine Arts, several km from its main campus. At least it's now on the correct side of the Harbour.
Anyway, all you need to do is open Bing maps in a neighbourhood you know well, to find dozens of businesses that you heretofore thought were located elsewhere: beach holiday resorts in suburban streets. It's hilarious.
Much of the data appears to come from the Australian Yellow Pages, which - from following links - seems to be years out of date. Obviously a poor partner for Bing's local offerings.
