A player by the name of "Lentebriesje" has embarked on one of the most extravagant virtual construction projects to date — recreating Earth in Minecraft. He's approached it one continent at a time and here's his/her interpretation of our very own Australia.
Like a lot of players that have attempted similarly epic efforts, Lentebriesje isn't building it by hand, rather he's using a tool called Worldpainter and importing maps from the National Oceanic and Atmospheric Administration. There's also the matter of scale — it's a 1:1500 recreation, as a full-scale one would probably kill something.
With most of the data handled, it's a matter of cleaning up the messy bits, with the end result visible at a closer perspective in the images below.
PS. And here's a list of co-ordinates if you're keen to see what your home city looks like (probably a lot more angular and barren than you remember).
