Crane in Dorothea 

Go down the ramp, then turn right off the platform and drop in down to 20 - 25mtrs, follow the road with the cliff on your right, round the corner and down to 35mtr, that's the jib. Back up the road, and round the corner, when the cliff is on your left, at 8mtrs is the tracked part. or something like that!

Not really, it's just a big hole in the ground full of water, so it's popular with scuba divers.

Im probalbly going to sound like the idiot here but is there a story behind Dorothea?

Nice vid dude, it was a much better dive when it was all at 35mtrs though. Check my vids out? Did em on me stills camera.lol.
