According to wikipedia, "n right hand traffic countries, revolving doors typically revolve counter-clockwise (as seen from above), allowing people to enter and exit only on the right side of the door. In left hand traffic countries such as Australia and New Zealand, revolving doors revolve clockwise, but door rotations are mixed in England."
Another interesting choice that pedestrians must make is which way to go through a revolving door. In North America and continental Europe, people keep to the right when they pass through revolving doors, and the door rotates counter-clockwise as viewed from above. Alex Boster reports that in Australia and New Zealand, the situation is reversed and people keep to the left. As a tourist, "the second biggest danger to life and limb... was not to get smacked in the face by a revolving door." Joe DeRose writes that in Atlanta (USA), there is a restaurant (the Tavern at Phipps) which has a "large antique revolving door at one of the entrances. A prominent sign on the door reminds people to enter to the left, and explains that the door was originally installed in London in 1908." Practice in the UK varies; you enter some doors on the right, and others on the left!
Here you can see a clockwise door in Australia.
