What if... started digging a hole in Penrith Library and went all the way through the planet's core to the oposite side of the globe. Where would you end up?

A while ago, when we visited the Greenwich Prime Meridian Line, I asked Graeme where you would end up if you dug a hole all the way through Earth, starting at Penrith. We agreed somewhere in the middle of the Atlantic Ocean, probably in the middle of nowhere. This was pretty much right, but to prove the point, Graeme sent me this link to the site of a guy who has used google maps to answer this exact question...

OK, so it doesn't look that impressive at this level, but trust me, its cool. I KNOW I dug the hole from Penrith Library because I zoomed right in on it. As you can see from the picture below, I took this screenshot at the second level of zoom, rather than right in so you can see other things around the library.

It wasn't too hard really - I worked out roughly where Sydney would be, went west, hit the river and followed it til I found the Lakes and from there you can examine all of Penrith. Go play with it if you have some time. I'm off to find the opposite side of the world to where I'm sitting right now.
