Here we have the 12 apostles recognised around the world as a great tourist attraction! These limestone stacks, up to 50 mts (160 ft) were formed over thousands of years of erosion along our coastline. They were formerly known as the Sow & piglets, but a user friendly new name was given in the 1960's as tourism started booming! I've found a photo of mine when we visited in 1970 (not knowing then I would move down here!) Here you can see the front stack which fell in 2005.
Thanks for sharing this opportunity to study the differences time has created. The others don't look greatly changed, but it's a shame the front form fell.
