Amazing lifelike sculptures by Ron Mueck

I was just using Stumbleupon and stumbled on these images of some spectacularly lifelike models but unfortunately, there was no information on who created them and where the images were taken. Can anyone shed any light?

Update: Many thanks to Steve VH for poitning out that the artists name is Ron Mueck. Thanks Steve.
