My second 'once in a lifetime' sight from our recent western australian trip was Shell Beach, Shark Bay.

I've dreamt of visiting this beach made entirely of shells since I was a child. It’s apparently one of only two such shell beaches in the world. It didn't disappoint.

Not only is this one very pretty beach, I was pleasantly surprised to find the Feral Proof Fence of Project Eden runs through it. 

The fence excludes feral animals such as foxes and feral cats, making the Peron Peninsula a safe haven for numerous threatened species, including the Bilby, which are being re-introduced back into the site. 

I'll be back soon to share my third and final 'once in a lifetime' sight from our trip (check out the first here if you missed it).
