Western Australia whose capital is Perth (where I live), is the State with most islands, a total of 3747! It would be hard to visit them all !!!
Just off the coast of Perth are the most known of WA´s islands – Rottnest, Carnac, Garden and Penguin Islands. Apart from Garden Island where public is not allowed I have been lucky to visit the other 3. In this post I will talk about Rottnest and Carnac islands, and the next post will be about Garden Island and the cutest … Penguin island.
