Dream Trips of the Future - Western Australia

I have been inside for so long, I've run out of house porn! So on to "Future Trip Dreams". I think someday I would like to take a nice long (like 2 or 3 week) trip to Western Australia. 

I think I would start in Perth for a few days to see the city and enjoy it. Get my land legs back. 

Take a day cruise on the swam river up to some wineries.

Take a day trip to Rottnest Island to see the Quokkas.

Then on to Exmouth Peninsula for some amazing snorkeling or diving on Ningaloo Reef with the Whale Sharks.
